Document Type and Number:
Japanese Patent JPH04502466
Kind Code:
A
Abstract:
In a process for producing esters of (meth)acrylic acid of polyvalent alcohols, the reagents are converted in the presence of acidic esterification catalysts, sterically blocked phenol compounds being added as polymerization inhibitors. The process is characterized in that tocopherols, some of which are preferably alpha-tocopherols, are used as sterically blocked phenol compounds. The reaction mixtures are preferably liquid at the reaction temperature and are essentially free from solvents and/or azeotropic entrainers, the water of condensation being removed from the gaseous phase in the reaction chamber.
