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.

摘要:
Disclosed are a polyester compound having a repeating unit represented by the formula--OC--A--COO--BO-- (1)wherein A is a 1,3:2,4-dibenzylidenesorbitol or 1,3:2,4-dibenzylidenexylitol residue of the formula ##STR1## wherein t is 1 or 0, and B is a residue formed by removal of two hydroxyl groups from a polyhydric alcohol, and an organic gelling agent comprising the polyester compound.
