Accordingly, the present invention provides a process for preparing polyglycerol from crude glycerol, wherein the crude glycerol having a glycerol content from about 60 to about 90%, soap content from about 10 to about 15% and methanol content from about 5 to about 20%, the process includes the steps of (a) heating the crude glycerol that contains soap to an elevated temperature for a certain reaction time, (b) acidifying the crude polyglycerol with mineral acid at a specific temperature and (c) centrifuging the acidified crude product obtained from step (b) at specific temperature for a certain duration of time.

Process of producing polyglycerol from crude glycerol

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 (a) heating the crude glycerol that contain soap to an elevated temperature for a certain reaction time by using a microwave technology, (b) acidifying the crude polyglycerol with mineral acid at a specific temperature and centrifuging acidified crude product obtained from step (b) at a specific temperature for a certain duration of time.
