REMOVAL OF ORGANIC SALTS FROM BIO-DERIVED GLYCOL PRODUCTS |
摘要 |
A method for reducing contaminants in the production of a bio-derived glycol product of polyol hydrogenolysis is described. The method involves subjecting an aqueous, polyol product mixture (from the hydrogenolysis conversion of biologically-derived carbohydrate feedstock) to ion-exclusion chromatography to separate and reduce impurities from an eluant fraction containing a desired product, and distilling the eluant fraction to yield the desired product (e.g., propylene glycol or ethylene glycol). The reaction product mixture can be introduced into a continuous ion-exclusion chromatography system to reduce the impurities and produce in a high-throughput manner a finished otherwise commercially acceptable glycol product. |
