The largest end uses for hydrochloric acid are steel pickling, oil well acidizing, food manufacturing, producing calciumchloride, and ore processing. Hydrochloric acid is a corrosive liquid, and it must be stored and handled with this hazard in mind.

Hydrochloric Acid Uses - Steel Pickling

Steel pickling is the process by which iron oxides and scale are removed from the surface of steel by converting the oxides to soluble compounds. Hydrochloric acid is used primarily for continuous pickling operations in which hot-rolled strip steel is passed through a countercurrent flow of acid solution.

Hydrochloric Acid Uses - Oil Well Acidizing

Hydrochloric acid is used both to remove rust, scale and undesirable carbonate deposits in oil wells to encourage the flow of crude oil or gas to the well. An acid solution is injected into the formation, which dissolves a portion of  the rock and creates a large pore structure in the formation, increasing its effective permeability and the flow of oil.

Hydrochloric Acid Uses - Food

A major use of hydrochloric acid by the food industry is for the production of cornsyrup such as high-fructose cornsyrup (HFCS). Hydrochloric acid is also used in other food processing applications, including the production of hydrolyzed vegetable protein and soy sauce.

learn more about Glacial Acetic Acid Structure

Because of acetic acid solidifies just below room temperature at 16.7буC (about 62буF); acetic acid can be concentrated by dripping the impure compound over a "stalactite" of glacial acetic acid; the pure acetic acid crystallizes, while impurities run off in the liquid; so that the water-free acetic acid is sometimes called glacial acetic acid.

Glacial Acetic Acid Chemical Formula is C2H4O2: Acetic Acid has two carbon (C) atoms, four hydrogen (H) atoms and two oxygen (O) atoms. Because Acetic Acid has a carbon in its chemical formula, it is an organic compound. Acetic Acid chemical formula can be written multiple ways, as shown here: C2H4O2; CH3COOH; CH3CO2H.

Glacial Acetic Acid Usage:

Glacial acetic acid is frequently used as a solvent for recrystallisation to purify organic compounds, as a solvent in the production of terephthalic acid (TPA), the raw material for polyethylene terephthalate (PET). Glacial acetic acid is a much weaker base than water, so the amide behaves as a strong base in the weakly alkaline substances, that Glacial acetic acid is used in analytical chemistry for the estimation of weakly alkaline substances such as organic amides.

Characteristics Of Methyl Isobutyl Ketone

Methyl isobutyl ketone is regarded as a solvent. It is usually used for spray paint, nitrocellulose, camphor, oils, natural and synthetic rubber. Its vapor and air form explosive mixtures. It is easy to cause burning or explosion when meet fire or high energy. Oxidant will react with methyl isobutyl ketone.

Since the vapor is more heavier than air, it could spread far on the lower level. With high heating, the internal pressure in the container would be increased and even exit dangerous of broken or explosion. Some plastics, resin and rubber could dissolved in methyl isobutyl ketone.

Methyl isobutyl ketone is often store in a cold and ventilated warehouse. It must be keep far away from fire and heat source. The temperature of warehouse could not upon 30℃. Certainly the container should also be seal up and without any sunlight.

After you using the methyl isobutyl ketone, you should pay more attention. At first, taking off contaminated clothing and wash with flow water. Related staff should get some knowledge about personal protection. If the methyl isobutyl ketone has been gotten into eyes. You must open the upper and lower eyelids immediately. At the same time, using flow water to clean about fifteen minutes. If it is very serious, you must take to hospital in time.

Water Treatment By Sodium Hydroxide

Sodium hydroxide is well known to everyone. It is also called caustic soda. But little people know about that could be regarded as a good tool for processing the water. Sodium hydroxide has strong alkaline and is easy to soluble in water. In water treatment factory, sodium hydroxide can reduce the hardness of water by neutralization reaction. In fact, it is also a regeneration agent for regeneration of ion exchange resin in the industrial field.

Generally speaking, caustic soda is exist as a kind of liquid. So people can measure how many consumption we have used very conveniently. At the same time, sodium hydroxide could adjust the pH value of water, neutralization the waste water and even elimination of heavy metal ions in water by precipitation.

Maybe little people know the sodium hydroxide is used for making paper. The original material for making paper is straw or wood. These materials have a lot of lignin,  gum and other non cellulose except many cellulose. Before making paper, we should separate unnecessary impurity with mechanical method. And then using the fiber to make paper. However this fiber of paper pulp is very short and paper will be in bad quality and easy to broken. At this time, you may try to use the sodium hydroxide to help. Cooking the original with sodium hydroxide solution. Then people would be very curious. Since the sodium hydroxide without any damage capability for cellulose component and could decomposition of non cellulose gum.

How To Eat Safe Vegetables

There is no doubt that fresh vegetables is most popular in our daily life. But little people known nitrite content is very little in the fresh vegetables. The content of nitrite will reach a peak after the vegetables have been stored about one to three days at room temperature. It will also reach a peak after vegetables have been stored about three to five days at cold storage conditions. So you should eat the fresh vegetables as soon as possible, especially for green leafy vegetables.

Many people think overnight food may produce carcinogenic nitrite. In fact, it is not correct. Because the nitrite is not carcinogenic, but the nitrosamine is carcinogenic. However it is not means that the overnight food is without any problem. Nitrite content in the overnight food is more higher than in the dishes which just doing. Nitrite can converted into nitrosamines in human body. So you had better eat overnight food as less as possible.

Since the nitrosamines carcinogen, we need to pay attention to eat more food which could inhibit the formation of nitrosamines. For example, the garlic can inhibit the nitrate reducing bacteria in the stomach and reduce the content of nitrite in the stomach. Besides we also suggest that you can drink tea in day time. Tea polyphenols in tea can also prevent the formation of nitrosamine.

Acetone In Our Life

Acetone can be used for preparing the organic glass monomer, bisphenol A, two acetone alcohol, glycol, methyl isobutyl ketone, methyl isobutyl carbinol, isophorone, isophorone, chloroform, iodoform and other important organic chemical raw materials. Acetone is regarded as an excellent solvent in the aspects of paint, acetate fiber spinning process and refining industry dewaxing.

Acetone is always with stimulation. In other words, acetone is a hazardous substances. We should pay more attention while using acetone. At first, you must wear a pair of rubber glove and antistatic clothing. If it is exceed the standard concentration in air, people must wear filtration mask or half mask. What’s more, people could not smoke in working site. Certainly you had better avoid to contact with the acetone again and again, and even for a long time.

Many people think it is difficult to make the water separate with the acetone. In fact, it could be come true. Now there is a permeable membrane that can separate them under room temperature completely. Of course, some people like to use salting out to achieve the goal. Acetone solubility in the saturated brine is smaller than in pure water. But it seems that waste of salt.

Use Epichlorohydrin More Carefully

Epichlorohydrin is an important kind of raw materials in organic synthesis and intermediates. It is applied to producing epoxy resin. And it also could be regarded as diluent for epoxy resin. In fact, making glycerol, nitroglycerin, glass steel, methacrylic acid glyceride, epichlorohydrin rubber, glycidyl derivatives, surface active agent and electrical insulation products all need epichlorohydrin.

Epichlorohydrin steam has a strong irritant to the respiratory tract. It will damage your lung, liver and kidney if you have been inhalation the epichlorohydrin steam for many times or long time. Certainly if there are epichlorohydrin with high concentration, it may make your central nervous system restrain and even lead to death. Don’t let the epichlorohydrin liquid contact with skin directly. That will burn your skin. During a long time, people inhalation of a small amount without any known. That is easy to cause neurasthenic syndrome and peripheral neuropathy.

If the epichlorohydrin has been leaked, you should evacuate the workers in contaminated area as soon as possible. And then bringing them to safety area. Don’t allow irrelevant personnel into the contaminated area. At the same time, cut off the fire source. What’s more, you can not contact with the leakage.

Malignant Tumor In Decoration

As we all known, we can not live in the house which has been decorated just now. Because there retention of some toxic substances. Formaldehyde is one of these toxic substances. Formaldehyde is a protoplasmic poison, it can bind with protein. After inhalation of formaldehyde with high concentrations, there will be serious stimulus to the respiratory tract and even cause edema, eye irritation, headache. Certainly it can also occur in bronchial asthma.

A variety of artificial plate use adhesives which may contain formaldehyde. Making new furniture, decorate walls and ground all need adhesives. Generally speaking, the place that use adhesives will always release of formaldehyde. Besides some chemical fiber carpet and paint contain amount of formaldehyde, too.


There are many harm to people’s health. The main harm of formaldehyde to health is stimulation to skin mucous membrane. If your skin contact with formaldehyde directly, it is easy to cause allergic dermatitis, pigmentation, and even cause necrosis. High concentrations of formaldehyde is also a genotoxic substance.
Formaldehyde is easy to soluble in water. Formaldehyde aqueous solution which contains the proportion of range from 35% to 40% is also called Faure Marin. Faure Marin has a bactericidal performance of anticorrosion. It could application to dipping biological specimen and disinfection to the seed.

Notes For Toluene Transport

Toluene could only transport by enterprises owned tanker on the railway. At the same time, they must apply to the relevant departments for approval. The transport vehicle which used for transporting toluene should be equipped with the varieties and number of fire fighting equipment and leakage emergency treatment equipment.

In summer days, we suggest people transport the toluene in the morning or evening. Groove which is used for transporting toluene had better set hole partition to reduce the shock and even let it not produce static electricity. Don’t mixed with oxidant or food chemicals. Toluene transit should prevent insolation, drench, anti high temperature. Keep far away from fire, heat source and the high temperature region. The shipment of vehicle exhaust pipe must be equipped with fire resistance device. Don’t handle them with machine equipment and tool which is easy to produce sparks. Driving according the prescribed route in the highway transportation, don’t stay in the residential areas and densely populated area.

Toluene is often storage in a cool and ventilated warehouse. It is usually kept far away from fire and heat resource. The room temperature can not be higher than 37℃ and the containers must be sealed.

How To Storage Trichloroethylene

Trichloroethylene is a good solvent. It is always regarded as cleaning agent and extracting agent. Trichloroethylene is used as an anthelmintic drug for producing four vinyl chloride. But it is used for veterinary anthelmintics for producing hexachloroethane.


Trichloroethylene is storage in the warehouse which is shade and ventilation. At the same time, you should keep far away from fire and heat source. The room temperature can not higher than 25℃ and relative humidity can not more than 75%. Package of trichloroethylene is required to seal up and it could not contact with air. Trichloroethylene should be separate from oxidizing agent, reducing agent, alkali, metal powder and edible chemicals. Don’t put them together. There must be varieties kinds and number of fire fighting equipment.

Worker who operate the trichloroethylene should wear self filter mask and protecting glass, antivirus working clothes and anti chemical gloves. People would like to use explosion-proof ventilation systems and equipment in order to prevent the steam leakage in the air of workplace. Workers should pay more attention while carrying trichloroethylene to avoid damaging the packaging and containers. Sometimes the empty containers may remain harmful substances.
