| Abstract: | Synthesis of N - methyl methanesulfonamide was achieved by reacting methanesulfonyl chloride and gas methylamine in 1,2 - dichloroethane as solvent and controlling temperature between 20 - 30℃. Gas bleeding was executed after reaction completed, then the reaction suspension was filtered. 1,2 -dichloroethane was recycled by distilling filtrate under vacuum. N - methyl methanesulfonamide was received by high vacuum. The yield of the destination product was more than 93%, and the purity was more than 99%. |
