| Use | 2, 6-dichlorobenzaldehyde oxime is an important intermediate in the synthesis of benzoylurea insecticides. It is used to synthesize the next intermediate 2, 6-dichlorobenzonitrile, and finally obtain pesticide varieties such as fluoroburon, pyridorea, fluoridinamide, and lice-mite urea. In addition, 2, 6-dichlorobenzyl benzaldehyde oxime is also a kind of medicine Intermediate, for the production of diclofenazole penicillin sodium. As a pharmaceutical intermediate, used to make diclofenazole penicillin sodium. is a pharmaceutical intermediate, mainly used to make diclofenazole penicillin sodium drug |
| production method | 2, 6-dichlorotoluene is mixed with thionyl chloride, phosphorus trichloride is used as a catalyst, under ultraviolet light irradiation, heating to 200 ℃, passing chlorine gas for reaction, and absorbing the tail gas with liquid alkali until the weight is increased to the theoretical weight to obtain 2, 6-dichlorobenzyl dichloride, which is added to sulfuric acid, under stirring, heat to 50-55 ℃, react for 3 hours, then add hydroxylamine hydrochloride in times, keep the temperature for 3 hours, slowly add the reaction product into ice water, keep stirring, filter, and wash with cold water. The preparation method is to use 2, 6-dichlorobenzyl dichloride as raw material for oxime to obtain 2, 6-dichlorobenzaldehyde oxime. Add 2, 6-dichloro-dichlorobenzyl to sulfuric acid and heat slowly with stirring. React at 50~55 ℃ for 3h, then add hydroxylamine hydrochloride in several times, keep the temperature for 3h after adding, slowly add the reactants into ice water, stir continuously, filter after adding, rinse with a small amount of cold water to obtain 2, 6-dichlorobenzaldehyde oxime. |
