CATALYST FOR MANUFACTURING ACRYLIC ACID AND/OR ACRYLATE FROM LACTIC ACID AND/OR DERIVATIVE THEREOF, AND METHOD FOR MANUFACTURING ACRYLIC ACID AND/OR ACRYLATE

摘要

This catalyst is for manufacturing acrylic acid and/or an acrylate from lactic acid and/or a derivative thereof by dehydration, wherein the catalyst contains a phosphate compound including both an alkali metal and an alkaline-earth metal. This method for manufacturing acrylic acid and/or an acrylate has a step for obtaining the acrylic acid and/or acrylate from lactic acid and/or a derivative thereof by dehydration using this catalyst.
