CATALYST FOR PRODUCING ACROLEIN AND ACRYLIC ACID THROUGH GLYCERIN DEHYDRATION AND PRODUCTION METHOD OF SAME

摘要

Catalyst used in a process for preparing acrolein and acrylic acid at higher yield to convert glycerin to valuable other chemical raw materials. The glycerin dehydration catalyst consists mainly of a compound containing at least one element selected from Mo, W and V, in which protons in the heteropolyacid are exchanged at least partially with at least one cation selected from elements belonging to Group 1 to Group 16 of the Periodic Table of Elements.
