| Abstract: | A new synthesis process for chloroform and dimethylformamide by the reaction of alkalizing and deacidifying chlorine oil and dimethylamine was studied. The process conditions were optimized by orthogonal experiments as follows: the reaction temperature was 50℃,the holding time 60 min,dimethylamine and chlorine oil ingredient mol ratio 1 ∶ 1.10.Under the conditions,the yield of chloroform-aldehyde and DMF-aldehyde was 94.02% and 92.05%,respectively. The quality of pilot product produced by the new process is better than that of the product produced by lime process,the quality of chloroform met the high-class required by National Standard GB 4118 -92,DMF products met the requirement of HG 2028 - 91. |
