2-Chloro-N-methyl-3-oxobutanamide Use and Manufacturing

Methods of Manufacturing

The preparation method is obtained by chlorination of acetoacetamide. Put the acetoacetamide aqueous solution in the enamel reaction kettle, add the urine brine made of salt and urea, add a small amount of dichloroethane, stir and cool to below -15℃, then slowly pass in chlorine gas, and pass it in a certain amount. After sampling and analysis, it was pumped into the extraction kettle, heated to 40°C, and extracted with dichloroethane. The extract was pumped into the concentration kettle, and dichloroethane was evaporated under normal pressure to obtain α-chloroacetoacetamide. , Can directly enter the synthesis kettle for the next reaction.

Uses

Alpha-chloroacetoacetamide is a special intermediate for the insecticide crosophile.
