Chemical properties:
2, 4-dichlorophenone is white crystal, m.p.33 ~ 34℃, b.p.128 ~ 131℃/2.4kpa, n20D 1.5635, insoluble in water, soluble in benzene, toluene, alcohol and other organic solvents.
Uses:
2, 4-dichlorophenone is the raw material for the preparation of ω-bromo-2, 4-dichlorophenone or ω-2, 4-trichlorophenone, the latter two are the intermediates for the preparation of bactericides such as apromazole, propiconazole, ethyclozole, and also the intermediates of the insecticide fenazol and the herbicide wild yanquat.
Production method:
The preparation method is to add M dichlorobenene into the reaction bottle, the temperature is raised to 50℃, add an appropriate amount of anhydrous aluminum trichloride under stirring, maintain the temperature at 50℃, add acetyl chloride drops, gradually increase the temperature to 100℃ after dropping, and stir at this temperature for 8h, after the reaction is finished, add Chemicalbook dichloromethane into the reaction liquid and pour it into water, and place it to cool. The oil layer was separated, the water layer was extracted with methylene chloride, the organic layer was incorporated into the organic layer, the organic layer was washed with water, dried, the solvent was steamed and the vacuum distillation was carried out, and the fraction of 160 ~ 180℃/0.015MPa was collected to obtain 2, 4-dichlorophenone as white crystal.
