Application 2, 6-dichlorobenzaldehyde is an important intermediate in the synthesis of benzoylurea insecticides, it is used for the synthesis of the next Intermediate 2, 6-dichlorobenzaldehyde oxime, and finally obtains the pesticide varieties such as fluifolide, difenuron, floxuramide, and picosolide. In addition, it is also an intermediate of dye and medicine.
for synthetic dyes, also for fungicides and for the manufacture of herbicide 2, 6-dichlorobenzonitrile
for synthetic dyes, fungicides and for the manufacture of herbicide 2,6-dichlorobenzonitrile, etc.
intermediates for the synthesis of dyes, pesticides and pharmaceuticals. Mainly used for the production of acid medium B. It can also be used in the pharmaceutical industry to prepare diclofenac sodium.
production method synthesis of 2, 6-dichlorobenzaldehyde with P-nitrotoluene as starting material, 2, 6-dichlorotoluene, then 2, 6-dichlorobenzaldehyde can be obtained by direct oxidation of 2, 6-dichlorotoluene, and 2, 6-dichloro-benzylchloride can also be obtained by chlorination, and then 2, 6-dichlorobenzaldehyde. 2, 6-dichlorotoluene and potassium permanganate are mixed in concentrated sulfuric acid, and 2, 6-dichlorobenzaldehyde can be obtained by one-step reaction, but there are problems of acid solution application and "three wastes" treatment, moreover, a large amount of expensive manganese salt is consumed. 2, 6-dichlorotoluene is chlorinated at 120-140 ° C. In the presence of a free radical generator such as azobisisobutyronitrile, benzoyl peroxide, tert-butyl hydroperoxide, etc, 6-dichloro-benzyl chloride. 2, 6-dichloro-benzyl chloride can be hydrolyzed under different conditions to give 2,6-dichlorobenzaldehyde. Although this method increases the side chain chlorination reaction in one step, the reaction is easy to proceed and the yield is high. In addition, 2, 6-dichloro-benzaldehyde can also be prepared by heating 2, 6-dichloro-benzylchloride in a catalyst and an aromatic sulfonic acid medium. For the synthesis of 2, 6-dichlorotoluene, see "pyrethroid Intermediate".
