a,a-Dichloro-N,N-Diethylacetylacetamide Use and Manufacturing
The preparation method is obtained by chlorination of acetoacetyldiethylamine. At a temperature of 20°C, a certain amount of sulfuryl chloride was slowly added dropwise to acetoacetyldiethylamine, the reaction temperature was increased to 47°C, and the reaction was continued for 20 minutes. The low-boiling substances were evaporated under reduced pressure with mercury and the remainder was benzene Dilute, wash with NaHCO3 and water to neutrality, dry, remove the solvent, and distill under reduced pressure to obtain the product α, α-dichloro-N, N-diethylacetoacetamide with a yield of 85%. Switch to direct chlorination with chlorine.
α,α-Dichloro-N,N-diethylacetoacetamide is a special intermediate for organophosphorus insecticide phosphoramide.
