| titleOfInvention | A kind of method that carbonylation prepares formamide |
| abstract | The present invention relates to a kind of method for preparing formamide.This method, as reactant, under catalytic action, formamide is prepared by carbon monoxide carbonylation using primary amine and/or secondary amine and carbon monoxide.This method is characterized in that the acid metal composite oxide of ruthenium load is catalyst, and high efficiency is carried out under the conditions of relatively mild.Its course of reaction is as follows：Certain density primary amine and/or secondary amine are put into pressure vessel with a certain amount of catalyst, CO gases are poured, closed, at a temperature of 100 DEG C of ＞, reaction time ＞ 2h, stirring reaction obtains formamide.This method catalyst preparation is simple, and catalytic activity is high, and the yield of product formamide can reach 98%, and product and catalyst separation process are simple, and catalyst can be recycled for multiple times, and course of reaction controllability is high. |
