Process for the Preparation of (Meth)Acrylates of Tetra-Or Polyhydric Alcohols

摘要

Process for the preparation of acrylic and methacrylic acid esters by transesterification of (meth)acrylic acid esters of the formula I: where R₁ is H or CH₃ and R₂ is an alkyl radical having 1 to 40 carbon atoms, with alkanols which have four or more esterifiable hydroxyl groups, characterized in that 0.01 to 10% by weight, based on the total reaction mixture, of lithium amide catalysts are used as transesterification catalyst.
