A process of producing polyglycerol from crude glycerol

摘要

The present invention relates to a process for accelerated preparation of polyglycerol from crude glycerol using microwave irradiation as the heat element in the presence of soap as the catalyst. The process includes the steps of heating the crude glycerol that contains soap to an elevated temperature for a certain reaction time, acidifying the crude polyglycerol with mineral acid at a specific temperature and centrifuging the acidified crude product at specific temperature for a certain duration of time.
