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.

Application Of Good Dimethylformamide

Dimethylformamide is widely used as a chemical raw material and it is often regarded as a good solvent. In the process of synthetic fiber of wet spinning and polyurethane, dimethylformamide is necessary. In daily life, people is habit to use dimethylformamide to remove the paint. Some pigment who always has the characteristic of dye because that can dissolve pigment which with some low solubility.

Dimethylformamide can used as a gas absorbent in the petroleum chemical industry. Certainly it is also an important intermediate in organic reaction. Dimethylformamide can be used for the production of chlordimeform in pesticide industry. It can be used in to form many drugs in the pharmaceutical industry. Such as Iodine amine pyrimidine, iodine glycosides, antitumor ammonia acid, tranexamic acid, dexamethasone, megestrol acetate and chlorpheniramine sensitivity. It has catalysis in the reaction of hydrogenation, dehydrogenation, dehydration and dehydrohalogenation.

People must evacuate quickly to a safe area once leakage. Experts always suggest that emergency treatment staff wear self positive pressure respirator and protective clothing for firefighters. Of course, people could use sand or other non combustible material to absorption if there is a small amount of leakage.
