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,公开了一种生产三羧酸三(烷基取代的环己胺)的工艺,该工艺包括将三羧酸和烷基取代的环己胺进行酰胺化反应、(a)在硼酸化合物和苯酚化合物存在的情况下,或(b)在硼酸化合物和苯酚化合物脱水缩合得到的硼酸酯存在的情况下,进行酰胺化反应,并选择性地纯化得到的粗反应产物。
