Synthesis method

The preparation method is 2,6-Chlorination of dichlorotoluene yields 2,6-Dichloro–Dichlorobenzyl.
Xianxiang 2,6-Add thionyl chloride to dichlorotoluene, and use phosphorus trichloride as a catalyst , under ultraviolet irradiation at 200℃通 Add chlorine gas, and then use alkali solution to absorb the remaining gas until the mass increases to reach the theoretical amount, and you will get 2, 6- Dichloro– Benzyl dichloride.

Purpose

2,6-Dichloro–Dichlorobenzyl also known as 2,6-二 Chlorobenzylidene dichloride, an important intermediate for the synthesis of benzoyl urea pesticides 2,6-Dichlorobenzaldehyde or 2,6-二 Chlorobenzaldehyde oxime is also an intermediate of the antibiotic diclofenac and penicillin.
