Economical and efficient processes for producing an &agr;, &bgr;-unsaturated carboxylic acid heterocycle-inserted ester and an &agr;,&bgr;-unsaturated carboxylic acid polyheteroalkylene ester as well as a catalyst suited for use in economically and efficiently producing an &agr;,&bgr;-unsaturated carboxylic acid ester are provided.
The invention provides
(1) a process for producing an &agr;,&bgr;-unsaturated carboxylic acid ester which comprises reacting an &agr;,&bgr;-unsaturated carboxylic acid ester with a heterocyclic compound,
(2) a process for producing an &agr;,&bgr;-unsaturated carboxylic acid ester
which comprises reacting an &agr;,&bgr;-unsaturated carboxylic acid with a heterocyclic compound
in the presence of a polymerization inhibitor and a metal oxide catalyst, and
(3) a catalyst for the production of an &agr;,&bgr;-unsaturated carboxylic acid ester
comprising a metal oxide.
本发明提供了经济、高效地生产&agr;,&bgr;-不饱和羧酸杂环插入酯和&agr;,&bgr;-不饱和羧酸聚异烯烃酯的工艺,以及适合用于经济、高效地生产&agr;,&bgr;-不饱和羧酸酯的催化剂。
本发明提供
(1)一种生产&agr;,&bgr;-不饱和羧酸酯的工艺,它包括使&agr;,&bgr;-不饱和羧酸酯与杂环化合物反应、
(2) 一种生产&agr;,&bgr;-不饱和羧酸酯的工艺,其中包括将&agr;,&bgr;-不饱和羧酸酯与杂环化合物反应。
其中包括使不饱和羧酸与杂环化合物反应
在聚合抑制剂和金属氧化物催化剂存在下反应,以及
(3) 用于生产&agr;,&bgr;-不饱和羧酸酯的催化剂
包括一种金属氧化物。
