    • 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 a 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
    • 本发明涉及一种制备N,N-取代氨基醇的(甲基)丙烯酸酯(F)的方法,其中N,N-取代的氨基醇(I),其中Y和Z各自独立地为C 1 -C 20 - 烷基,C 3 -C 15 - 环烷基,芳基或Y和Z与连接它们的氮原子一起形成5-至9-元饱和杂环基,其任选具有氧,硫,氮或C 1 -C 4 - 烷基取代的氮作为 另外的杂原子,X是可被1-10个不相邻的氧基和/或未被取代的或甲氧基取代的C 1 -C 4烷基亚氨基或C 3 -C 15 - 亚环烷基间隔的C 2 -C 20亚烷基,其中至少有一个 (甲基)丙烯酸酯(D)在至少一种非均相催化剂(K)的存在下使用,其中非均相催化剂(K)不使用任何其它溶剂而使用,反应混合物中的聚合抑制剂的含量<450ppm,和 涉及使用N,N-取代的氨基醇的(甲基)丙烯酸酯(F)。
