Catalyst for synthesizing isophorone dicarbamate n-butyl ester by urea method

The invention discloses a catalyst for a process for synthesizing isophorone dicarbamate n-butyl ester by a urea method. The catalyst comprises at least one of zinc acetate, manganese acetate, zirconium acetate and cobalt acetate; the catalyst is used for synthesis of isophorone dicarbamate, and the synthesis process comprises the following steps: taking IPDA, n-butyl alcohol, urea and the catalyst to carry out an alkoxycarbonylation reaction of organic amine, introducing a carrier gas in the alkoxycarbonylation reaction to separate a byproduct ammonia component, and reacting to obtain isophorone dicarbamate and synthesis tail gas. The catalyst has the advantages of good selectivity and high catalytic efficiency. 本发明公开了用于尿素法合成异佛尔酮二氨基甲酸正丁酯工艺的催化剂，所述催化剂包括醋酸锌、醋酸锰、醋酸锆、醋酸钴中的至少一种；所述催化剂用于异佛尔酮二氨基甲酸正丁酯的合成，所述合成的工艺为：取IPDA、正丁醇、尿素和所述催化剂进行有机胺的烷氧羰基化反应，所述烷氧羰基化反应中通入载气以分离副产物氨组分，反应得到异佛尔酮二氨基甲酸正丁酯和合成尾气。所述催化剂，具有选择性好、催化效率高的优点。
