  Reaction of methyl acrylate with N,N-dimethylethanolamine in the presence of a titanium alkoxide

  摘要：

  The kinetic features were examined for transesterifi cation of methyl acrylate with N,N-dimethylethanolamine in the presence of tetra(N,N-dimethylaminoethyl) titanate at different molar ratios of the reactants and at temperatures within 50-80A degrees C, as well as for side reactions of Michael addition at 95-125A degrees C. The major parameters governing the selectivity of the synthesis of N,N-dimethylaminoethyl acrylate were determined.

  The invention relates to a method for producing a (meth)acrylic ester with improved productivity, by transesterfication of a light alkyl (meth)acrylate with a heavy alcohol. The method of the invention includes the recycling of noble products recovered after the thermal treatment of heavy fractions generated during the synthesis, said thermal treatment being carried out in the presence of a dialkyl phthalate, the alkyl chain of which corresponds to that of the light alkyl (meth)acrylate. The invention applies to the production of N,N-dimethyaminoethyl acrylate from ethyl acrylate.

  本发明涉及一种通过轻烷基（甲基）丙烯酸酯与重醇的酯交换反应生产（甲基）丙烯酸酯的方法，该方法可提高生产率。本发明的方法包括对合成过程中产生的重馏分进行热处理后回收的惰性产品进行再循环，所述热处理是在邻苯二甲酸二烷基酯存在下进行的，该邻苯二甲酸二烷基酯的烷基链与轻烷基（甲基）丙烯酸酯的烷基链相对应。本发明适用于从丙烯酸乙酯生产 N,N-二甲基氨基丙烯酸乙酯。

  The invention relates to a process for recovery of noble products from heavy (meth)acrylic fractions generated during production of (meth)acrylic esters by transesterification, the heavy fractions comprising at least noble products and Michael adducts, the process comprising the steps of: (i) adding at least one antifouling agent and optionally a viscosity-reducing compound to the heavy fractions; (ii) submitting the mixture to temperature and distillation conditions sufficient to crack the Michael adducts into their components; and (iii) recovering the noble products in the form of a stream of distillate, and of a final residue that is sufficiently fluid to be transported by pump.
