Способ получения метилформиата карбонилированием метанола в присутствии метилата калия или натрия в качестве катализатора усовершенствован с целью уменьшения удельного расхода катализатора и интенсификации процесса. С этой целью в смесь карбонирования добавляют определенные количества оксаперфторалкансульфонатов натрия или калия общей формулы C2F5(OCFXCF2)пOC2F4O3M, где М = Na, K; X = F,CF3; n = 0 - 2 и до 10 мас.% сильных органических оснований. Реакцию осуществляют в реакторе с циркуляционным насосом. Соли натрия - продукты превращений метилата натрия - выделяют при помощи фильтра. Фильтрат подвергают ректификации и кубовый продукт повторно направляют на карбонилирование. В качестве дистиллята получают метилформиат, причем достигают высокой производительности процесса.The method of producing methyl formate by carbonylation of methanol in the presence of potassium methylate or sodium as a catalyst has been improved in order to reduce the specific consumption of the catalyst and intensify the process. With this purpose in carbonation mixture was added certain amount of sodium or potassium oksaperftoralkansulfonatov general formula C 2 F 5 (OCFXCF 2) n OC 2 F 4 O 3 M, where M = Na, K; X = F, CF 3 ; n = 0 - 2 and up to 10 wt.% strong organic bases. The reaction is carried out in a reactor with a circulating pump. Sodium salts - products of sodium methylate transformations - are isolated using a filter. The filtrate is subjected to rectification and the bottom product is re-directed to the carbonylation. Methyl formate is obtained as a distillate, and a high productivity of the process is achieved.
