Continuous production of methyl acrylate and acrylic acid via co-activation reaction of aldehyde condensation and esterification catalyzed by siloxane-functionalized vanadium phosphorus oxide-TiO2 catalyst

Abstract

A series of siloxane-functionalized vanadium phosphorus oxide (VPO)-TiO₂ catalysts were prepared by a wet-solid mechanochemical method and used to catalyze the co-activation reaction of aldehyde condensation with esterification, a novel route to significantly reduce carbon deposition and stably, efficiently, sustainably prepare methyl acrylate and acrylic acid.
