- 中文摘要: N-p-Chlorophenyl-N', N'-dimethylurea (CMU) was synthesized by the reaction of p-chlorophenyl isocyanate with dimethylamine in monochlorobenzene. The yield was 82.17%. p-Chlorophenyl isocyanate was prepared by heating p-chlorocarbamyl chloride, which was synthesized by phosgenation of p-chloroaniline in ethylene chloride. p-Chlorophenyl carbamyl chloride was crystallized as colorless needles from ethylene chloride.
