1. Mainly used as vinyl chloride; glycol; Acetic acid; Ethylenediamine; Tetraethyl lead; It is the raw material of polyethylenepolyamine and biformyl. It is also used as grease; Resin; Rubber solvent, dry cleaning agent, pesticide except morifolin; caffeine; vitamin; Hormone extractant, wetting agent, soaking agent, petroleum dewaxing agent, anti-seismic agent, pesticide manufacturing and drug Miechongning; The raw material of piperazine. It can be used as food in agriculture; Fumigant for grain; Soil disinfectant, etc.
2. Used for boron analysis, oil and tobacco extractant. It is also used in the manufacture of acetylcellulose.
3. Used as analytical reagent, such as solvent, chromatographic analysis standard material. It is also used for the extraction of oil and for organic synthesis.
4. As detergent, extractant, pesticide and metal deoiling agent.
5. Used as solvent of wax, fat, rubber and grain insecticide.
Dangerous characteristics of dichloroethane: its vapor and air form an explosive mixture, which can cause combustion and explosion in case of open fire and high heat. It can react strongly with oxidant. Toxic corrosive gases are produced by high thermal decomposition. Its vapor is heavier than air, it can diffuse to a far place at a lower place, and when it meets with fire source, it will ignite back. In case of high heat, the internal pressure of the container will increase, and there is a risk of cracking and explosion. Corrosion of plastics and rubber. Flammability (red): 3 reactivity (yellow): 0
Combustion (decomposition) products: carbon monoxide, carbon dioxide, hydrogen chloride, phosgene.
Stability: stable
Contraindications: strong oxidants, acids, bases.
Polymerization hazard: cannot appear
Fire extinguishing methods: foam, dry powder, carbon dioxide, sand and fog water. If the substance or contaminated fluid enters the waterway, inform downstream users with potential water pollution, local health and fire officials and pollution control departments.
Leakage disposal
Evacuate the personnel from the contaminated area to the safe area, prohibit irrelevant personnel from entering the contaminated area, and cut off the fire source. It is suggested that emergency personnel should wear protective equipment. Plugging under the condition of ensuring safety. Spray mist will reduce evaporation, but it can not reduce the flammability of leakage in restricted space. It is absorbed by sand, vermiculite or other inert materials, and then collected and transported to the waste treatment site for disposal. It can also be washed with emulsion made of non combustible dispersant and treated by diluted washing water into the waste water system. If there is a large amount of leakage, it will be collected, transferred and recycled by dike, and the contaminated site will be treated harmlessly.
