Document Type and Number:
WIPO Patent Application WO/2018/094691
Kind Code:
A1
Abstract:
The present invention provides a method for preparing acrylic acid and methyl acrylate. The method comprises: raw gas containing dimethoxymethane and carbon monoxide by means of a solid acid catalyst, at a reaction temperature of 180-400ºC, and under a reaction pressure of 0.1-15.0 MPa, with the feeding space velocity of dimethoxymethane being 0.05-10.0h-1 and the content of dimethoxymethane in percentage by volume being 0.1-95％, generates acrylic acid and methyl acrylate at a high conversion rate and selectivity.
