Process for preparing methyl acrylate or mixtures thereof with acrylic acid

摘要

Methyl acrylate alone or in mixture with acrylic acid is prepared by passing a gaseous stream containing methanol, acrolein and oxygen at a velocity of 5 to 50 cm/sec through a fluidized catalytic bed formed of spherical particles 15 to 100 mu in size, said particles comprising from 10 to 80 wt.% silica support, the remainder consisting of an active catalytic component defined by one of the general formulae:
