阅读说明：本技术 制备苯胺或苯胺衍生产物的方法 (Process for preparing aniline or aniline derived products ) 是由 J·朗安克 F·贝格尔 G·耶格尔 W·克洛克纳 V·米歇尔 T·弗斯辛 于 2019-07-24 设计创作，主要内容包括：本发明涉及制备苯胺或苯胺衍生产物的方法,其中氨基苯甲酸在苯胺中的溶液在165℃至500℃的温度下在不存在体系外催化剂的情况下经受热脱羧,使得氨基苯甲酸转化为苯胺,其中基于氨基苯甲酸和苯胺的总质量计,苯胺在所述溶液中的质量比例为20%至85%。所得苯胺可转化为衍生产物,例如二苯基甲烷系列的二胺和多胺。(The present invention relates to a process for the preparation of aniline or an aniline-derived product, wherein a solution of aminobenzoic acid in aniline is subjected to thermal decarboxylation at a temperature of 165 ℃ to 500 ℃ in the absence of an out-of-system catalyst, such that aminobenzoic acid is converted into aniline, wherein the mass proportion of aniline in the solution is 20% to 85% based on the total mass of aminobenzoic acid and aniline. The resulting aniline can be converted into derivative products, such as di-and polyamines of the diphenylmethane series.)
