ABSTRACT:
Sebacic acid is produced from adipic acid by half esterifying adipic acid with methanol to produce monomethyl adipate, carrying out electrolytic condensation of the monomethyl adipate in a methanol solution containing an alkali metal salt of the monomethyl adipate to give an electrolytic solution containing dimethyl sebacate, treating the electrolytic solution by a combination of water treatment and anion exchange treatment or a combination of cation exchange treatment and anion exchange treatment to remove the monomethyl adipate and its alkali metal salt from the electrolytic solution, separating the dimethyl sebacate, and hydrolyzing the dimethyl sebacate to give sebacic acid.
