摘要：
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.
