Disclosed are, for example, a process for producing a tricarboxylic acid tris(alkyl-substituted cyclohexylamide), the process comprising subjecting a tricarboxylic acid and an alkyl-substituted cyclohexylamine to an amidation reaction, either (a) in the presence of a boric acid compound and a phenol compound or (b) in the presence of a boric acid ester obtained by the dehydration condensation of a boric acid compound and a phenol compound, and optionally purifying the resulting crude reaction product.
例如,本发明公开了一种生产三羧酸三(烷基取代的环己基)酰胺的方法,该方法包括将三羧酸和烷基取代的环己基胺置于酰胺反应中,(a)在硼酸化合物和酚化合物的存在下或(b)在通过脱水缩合一种硼酸化合物和一种酚化合物所得的硼酸酯的存在下进行反应,并可选择性地纯化所得的粗反应产物。
