Title: Production of sorbic acid
Inventor: NAKAJIMA MASAHIRO
IPC: C08G63/88
Filed: 1990-10-15
Abstract: PURPOSE:To industrially and advantageously obtain sorbic acid by dissolving a polyester prepared by reacting crotonaldehyde with a ketone in a specific solvent, washing the resultant solution with water, etc., continuously bringing the washed solution into contact with a strong acidic porous type ion exchange resin and decomposing the polyester. CONSTITUTION:A polyester obtained by reacting crotonaldehyde with a ketone in the presence of zinc salt of an organic acid is decomposed to produce sorbic acid useful as a food preservative. In the process, the aforementioned polyester is dissolved in an aromatic hydrocarbon-based solvent having 92-100 deg.C azeotropic temperature with water. The resultant polyester solution is subsequently washed with water or an aqueous mineral acid to remove zinc. The washed solution is then continuously brought into contact with a strong acidic porous type ion exchange resin at 60-95 deg.C temperature to enable continuous operation of a polyester decomposing apparatus for a long period according to a simple method and simultaneously provide the objective compound which can be readily purified in high yield.
