Title:

METHODS FOR REMOVING VICINAL DIOLS FROM LACTIC ACID FERMENTATION BROTH

Document Type and Number:

WIPO Patent Application WO/2010/104677

Kind Code:

A3

Abstract:

Embodiments of a method for removing vicinal diols from a lactic acid fermentation broth comprise the steps of contacting the lactic acid fermentation broth with functionalized silica comprising at least one hydrophobic ligand to facilitate binding of the vicinal diols to the hydrophobic ligand, and separating the contacted lactic acid fermentation broth from the functionalized silica to remove the vicinal diols.
