Application of 14062-80-7, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 14062-80-7, name is 4-Chloro-N,N-dimethylbenzamide, This compound has unique chemical properties. The synthetic route is as follows.

It is cooled and a solution of 408g (3 moles) of sodium acetate trihydrate in 1600 ml of water is added dropwise for 45 minutes, after which the mixture is again heated under reflux for 30 minutes. The resulting mixture is poured onto ice, the organic layer is separated, and the aqueous layer is washed with chloroform. The combined organic solutions are washed with sodium bicarbonate and brine and dried over magnesium sulfate. Evaporation of the solvent in vacuo gives a dark oil, which is distilled in vacuo through a heated Vigreaux column to give a white solid; mp 106-9 C. It is recrystallized from cyclohexane to give 2-p-chlorobenzoylpyrrole as white needles; m.p. 110-113 C.

The chemical industry reduces the impact on the environment during synthesis 4-Chloro-N,N-dimethylbenzamide. I believe this compound will play a more active role in future production and life.
