Abstract
A process for vapor-phase carbonylation of methanol to methyl formate, whereby a feed gas containing methanol, carbon monoxide, hydrogen and oxygen is passed through a reactor loaded with a supported nano-scaled platinum group metal heterogeneous catalyst to produce methyl formate by a vapor-phase carbonylation reaction, under reaction conditions with a space velocity of 500-5000 h, a temperature of 50-150° C. and a pressure of 0.01-2 MPa. Supported nano-scaled platinum group metal heterogeneous catalysts are prepared via ultrasonic dispersion and calcination. Methyl formate is produced and isolated under relatively mild conditions.
