DIETHYLALUMINIUM CHLORIDE - Reference Information

chemical properties	colorless transparent liquid. Soluble in gasoline and aromatics.
use	mainly used as polymerization catalyst for polyolefin, butyl rubber and ethylene propylene rubber and intermediate for synthesis of organometallic compounds and contraceptives promoter for propylene polymerization reaction, low pressure polyethylene catalyst; Ethylene propylene rubber, polyisobutylene, aromatic hydrocarbon hydrogenation and other reaction catalysts; Rockets, missile fuels and aluminized raw materials. Diethyl aluminum chloride is strongly destructive to human tissues, causing chemical burns in contact with the skin, and reacting with oxygen in the air to produce toxic and corrosive smoke, which strongly stimulates respiratory organs.
production method	1. aluminum iodine method (double half method) The chloroethane dried by aluminum trioxide reacts with aluminum powder in the presence of activator iodine and double ethyl aluminum chloride to generate double ethyl aluminum chloride (double half for short), which then reacts with metal sodium or sodium chloride, that is, diethyl aluminum chloride is obtained. 2. The chloroethane refined by the aluminum-magnesium alloy method reacts with the aluminum-magnesium alloy activated by ball milling and monochlorodiethylaluminum, and the finished product is obtained after evaporation. 3. In the direct method, triethyl aluminum and hydrogen are added to the activated aluminum to react to form diethyl aluminum hydrogen, and then ethylene is used to react with it to form triethyl aluminum. Triethyl aluminum reacts with aluminum trichloride to produce diethyl aluminum chloride. Raw material consumption (kg/t), aluminum iodine method aluminum powder ≥ 99.5% 400 chloroethane ≥ 99% 1460 iodine ≥ 99.5% 8 sodium metal ≥ 99.5% 134.5
