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.

what is the common name of acetic acid?

Acetic acid is both common names, is the official name of the International Union of Pure and Applied Chemistry (IUPAC) regulations. Because the main component of vinegar, commonly known as acetic acid. Anhydrous acetic acid at slightly below room temperature (16.7 ℃), can be converted into an ice-like crystals have a corrosive, so often referred to as glacial acetic acid, acetic anhydride.

what products contain acetic acid?

For example, in the fruit or vegetable in major presence in the form of an ester compound; in animal tissue, feces and blood in the free acid form.

Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid with a freezing point of 16.6 °C (62 °F), solidified as colorless crystals. Although based on an aqueous solution of acetic acid dissociation ability it is a weak acid, but acid is corrosive, its steam eye and nose irritation effect.

uses of glacial acetic acid:

Acetic acid is a simple carboxylic acid is an important chemical reagent. Acetic acid has also been used to produce the desired footage cellulose acetate and wood adhesives of polyvinyl acetate, as well as many synthetic fibers and fabrics.

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.
