| Abstract: | Based on the analysis of the composition of the crystal substance in production of N,N|dimethylformamide by one|step technique, the reason of the crystal substance growing is explained. A cleaner process for the production of N,N|dimethylformamide is developed. Compared to the one|step technique, the cleaner process prevents pollution to environment, and raises the unit yield and gets more yields per raw material, so reduces production costs. |
