Title:
Ｎ，Ｎ−置換アミノアルコールの（メタ）アクリル酸エステルの製造方法
Document Type and Number:
Japanese Patent JP5882334
Kind Code:
B2
Abstract:
The present invention relates to a process for preparing (meth)acrylic esters (F) of N,N-substituted amino alcohols, by transesterifying N,N-substituted amino alcohols (I) in which Y and Z are each independently C1-C20-alkyl, C3-C15-cycloalkyl, aryl, or Y and Z together with the nitrogen atom connecting them form a 5- to 9-membered saturated heterocyclic radical which optionally has oxygen, sulfur, nitrogen or C1-C4-alkyl-substituted nitrogen as a further heteroatom, and X is C2-C20-alkylene which may be interrupted by 1 to 10 nonadjacent oxy groups and/or unsubstituted or methoxy-substituted C1-C4-alkylimino groups, or C3-C15-cycloalkylene, with at least one (meth)acrylic ester (D) in the presence of at least one heterogeneous catalyst (K), wherein the heterogeneous catalyst (K) is used without any further solvent and the content of polymerization inhibitors in the reaction mixture is < 450 ppm, and to the use of the (meth)acrylic esters (F) of N,N-substituted amino alcohols.
