Determination of carbon monoxide as raw material for the preparation of N,N dimethylformamide by carbonylation of dimethylamine
Carbon monoxide determination of raw materials for the preparation of N,N dimethylformamide by carbonylation of dimethylamine Details:

A method for the preparation of N,N dimethylformamide (DMF) by the carbonylation of dimethylamine. This method uses dimethylamine and carbon monoxide (CO) as reactants, and under the action of catalysis, the carbonylation reaction of CO insertion is used to prepare DMF. The reaction conditions are as follows: the reaction is carried out in a fixed bed reactor, the reaction pressure is 1.0-8.0 MPa, the reaction temperature is 150-250 DEG C, and the dimethylamine feed space velocity is 50-800 h1. The method is characterized by (1) the reaction It has 100% atom economy and no by-products. (2) Using noble metal supported metal oxides or molecular sieves as catalysts, the catalyst is simple to prepare and catalyzes the reaction with high efficiency, and the yield of DMF can reach more than 80%.
