Title: Recovery equipment and recovery method for sorbic acid
Inventor: MIURA HIROSHI
IPC: C07C57/10
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To recover sorbic acid from the filtrate (mother liquor) resulting from the sorbic acid production process in high yield and reduce the BOD value in the liquid waste. SOLUTION: Crude sorbic acid formed in the polyester decomposition step 1 is fed to the crystallization step 2 to crystallize the sorbic acid and separate it from the mother liquor (filtrate). The resultant mother liquor is subjected to the extraction step 3, the extract (the organic phase) is subjected to the back extraction step 4 and treated with an aqueous alkali thereby extracting sorbic acid into the aqueous phase in its salt form. This aqueous phase is neutralized in the neutralization step 6 and the sorbic acid formed there is recovered in the separation step 7. As an extraction solvent, is used an organic solvent that has solubility of <=1 wt.% in water, can dissolve sorbic acid in a concentration of >=0.5 wt.% and is separable (immiscible) from the water phase (for example, aliphatic 6-20C alcohols, ketones, esters, aromatic ethers and the like).
