介绍了一种采用二甲胺代替石灰与氯油反应，在生产氯仿的同时联产N，N-二甲基甲酰胺的新工艺。该工艺的特点在于原料易得且价格低廉，具有独创性的萃取技术避免了使用干燥剂及其它助剂，理论上使三氯乙醛中碳的利用率达到100％，无甲酸盐类物质排放。新工艺中试产品的质量优于石灰法产品质量，氯仿质量达到国标GB4118-92优等品要求，DMF产品达到HG2028-91标准要求。而且采用新工艺后，公司氯仿成本比石灰法下降1 387.87元/t，环境污染问题也得到根本性解决，达到降低成本、保护环境的双重目的。

In this paper, a new chloroform production process by reaction of chlorinated oil with dimethyl amine instead of lime is introduced, in which N, N- dimethyl methanamide is coproduct. The characteristics of this process lie in that the raw materials are easy to get and have low prices,its unique extraction technology avoid using drying agent and other assistants, the use ratio of carbon contained in trichlroacetic aldehyde reaches to 100% and there aren't formate substances to be discharged. 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 reach to the high-class required by National Standard GB 4118-92,DMF products reach to the requirement of HG 2028-91. Moreover, with the adoption of the newprocess, the production cost of chloroform was reduced by1 387.87 RMB￥/t compared with that oflime process, and the problem of environment pollution was thoroughly solved,achieving the aims of production cost reduction and environmental protection.
