摘要：
In the process of distilling a polyol product mixture including one or both of a biobased propylene glycol and a biobased ethylene glycol from the reaction of hydrogen with a biobased feed, it has been discovered that undesirable epoxides can form, and the present invention provides means for guarding against their formation, for removing epoxides which do form by particular methods of distilling, and for removing the epoxides from a finished, otherwise commercially acceptable biobased glycol product .
