Use | 2, 4-dichlorobenzyl chloride is an intermediate of the fungicide benzylchlorotriazole. used in the preparation of 2, 4-dichlorobenzyl alcohol, 2, 4-dichlorobenzaldehyde, 2, 4-cyanogen chloride, 2, 4-dichlorobenzoic acid, 2,4-dichlorobenzoyl chloride and other intermediates of miconazole. |
production method | the preparation method is to take 2, 4-dichlorotoluene as raw material, add a little PCl3 as catalyst, heating to 120 ° C, chlorine gas under light conditions for chlorination, control the amount of chlorine gas and intermediate control by GC, the main is 2, 4-dichlorobenzyl chloride, there is also a small amount of 2, 4-dichlorobenzylidene dichloride. In addition, it is also possible to use azobisisobutyronitrile as a catalyst, at an appropriate temperature to 2, 4-dichlorotoluene as a raw material for chlorination, control the amount of chlorine gas, and GC intermediate control, can be obtained 2, 4-dichlorobenzyl chloride. |
