Abstract
A process for making a hydrogenated product comprising caprolactone (CLO) and 1,6-hexanediol (HDO) and derivatives thereof from adipic acid (AA) obtained from fermentation broths containing diammonium adipate (DAA) or monoammonium adipate (MAA).
Claims13
A process for producing a hydrogenated product from a clarified DAA-containing fermentation broth or MAA-containing fermentation broth comprising:
- (a) distilling the broth under super atmospheric pressure at a temperature of >100° C. to about 300° C. to form an overhead that comprises water and ammonia, and a liquid bottoms that comprises AA and at least about 20 wt % water;
- (b) cooling and/or evaporating the bottoms to attain a temperature and composition sufficient to cause the bottoms to separate into a liquid portion and a solid portion that is substantially pure AA;
- (c) separating the solid portion from the liquid portion;
- (d) hydrogenating the solid portion, in the presence of at least one hydrogenation catalyst to produce the hydrogenated product comprising at least one of CLO or HDO;
- and
- (e) recovering the hydrogenated product.

A process for producing a hydrogenated product from a clarified DAA-containing fermentation broth or MAA-containing fermentation broth comprising:
- (a) adding an ammonia separating solvent and/or a water azeotroping solvent to the broth;
- (b) distilling the broth at a temperature and pressure sufficient to form an overhead that comprises water and ammonia, and a liquid bottoms that comprises AA and at least about 20 wt % water;
- (c) cooling and/or evaporating the bottoms to attain a temperature and composition sufficient to cause the bottoms to separate into a liquid portion and a solid portion that is substantially pure AA;
- (d) separating the solid portion from the liquid portion;
- (e) hydrogenating the solid portion in the presence of at least one hydrogenation catalyst to produce the hydrogenated product comprising at least one of CLO or HDO;
- and
- (f) recovering the hydrogenated product.
