| titleOfInvention | The method that diethylaluminum monochloride goes to hydrolyze chlorination production |
| abstract | The present invention relates to the preparation method of a kind of diethylaluminum monochloride, include following steps: 1) low temperature chlorination: under room temperature, being passed through chlorine in diethyl sulfide, cooling, the HCl water that reaction produces absorbs；2) high-temp chlorination a: heating step 1) gained reactant liquor, add catalyst, continue secondary temperature elevation, then be incubated；3) crystallize: be incubated complete, adds crystallize auxiliary agent B, puts into filter sulfur, and filtrate is diethylaluminum monochloride crude product I；4) secondary crystallize: heated up by diethylaluminum monochloride crude product I, adds crystallize auxiliary agent C, puts into filter sulfur, and filtrate is diethylaluminum monochloride crude product II；5) refined: diethylaluminum monochloride crude product II distills to obtain product through decompression.Beneficial effects of the present invention: achieving the nothing hydrolysis chlorination production of diethylaluminum monochloride, eliminate generation and the discharge of the toxic and harmfuls such as the sewage of chlorination link, hydrogen sulfide, the consumption reducing raw material chlorine reaches about 15%, improves product yield about 5%. |
