Dichloroethane is an organic compound that is irritating and flammable. It is widely used in the field of chemical production raw materials, mainly for the manufacture of vinyl chloride, ethylene glycol and other chemicals. This article will detail the properties and uses of dichloroethane.

1. the nature of dichloroethane

1. physical properties
dichloroethane is a colorless transparent, volatile liquid, pungent odor. Its boiling point is low, 83.5 ℃, density than water, insoluble in water, but soluble in organic solvents.

2. Chemical properties
dichloroethane has high chemical stability, but it is prone to decomposition and chlorination under high temperature, light and acidic conditions. It also has a certain corrosive effect on metal equipment.

2. the use of dichloroethane

1. Manufacture of vinyl chloride
dichloroethane is an important raw material for the manufacture of vinyl chloride. Vinyl chloride is an important organic chemical raw material, mainly used in the production of polyvinyl chloride (PVC), widely used in construction, electrical, packaging and other fields.

2. Manufacture of Ethylene Glycol
Dichloroethane can also be used to manufacture ethylene glycol. Ethylene glycol is a colorless, odorless, sweet viscous liquid, can be used as a solvent, antifreeze and antifreeze.

3. Manufacturing other chemicals
In addition to vinyl chloride and ethylene glycol, dichloroethane can also be used to manufacture other chemicals, such as 1,1, 1-trichloroethane, carbon tetrachloride, etc.
Precautions for
3.
In the process of using dichloroethane, the following points need to be paid attention to:

1. Dichloroethane is irritating and flammable and needs to be stored in a cool and ventilated special warehouse. Keep away from fire and heat sources.
2. Dichloroethane has a certain corrosive effect on metal equipment, and special corrosion-resistant equipment is required.
3. Operators need to wear professional protective equipment to avoid direct contact with dichloroethane.

In short, dichloroethane is widely used in the field of raw materials for chemical production, but it is necessary to pay attention to safety matters during use to ensure the smooth progress of the production process.
