The invention relates to a process for preparing (meth)acrylic esters by esterifying (meth)acrylic acid or transesterifying at least one (meth)acrylic ester with at least one compound comprising at least one OH group in the presence of a heterogeneous catalyst comprising at least one inorganic salt, wherein the esterification or transesterification is performed in the presence of 300 to 3000 ppm of water based on the total weight of the reaction mixture.

Process for preparing (meth)acrylic esters

Provided is a process for preparing a (meth)acrylic ester (F) of an N-hydroxyalkylated lactam, in which a cyclic N-hydroxyalkylated lactam (L): where the structural variables as defined herein, in the presence of at least one metal salt of C-C-alkoxides (A), is esterified with (meth)acrylic acid (S) or transesterified with at least one (meth)acrylic ester (D), in which the metal salt of C-C-alkoxides (A) used as a catalyst is added in the absence of solvents and completely at the start of the reaction.
