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.

A process for producing oleochemical polyols comprises the steps of epoxidizing unsaturated oil using an organic acid together with oxygenated water or a per-acid to obtain epoxidized oil; washing the epoxidized oil with salt water to remove unused organic acid together with oxygenated water or a per-acid; neutralizing acidic condition of the washed epoxidized oil with a base; washing the neutralized epoxidized oil with a salt solution until the pH of the neutralized epoxidized oil reaching 6.5 to 7.5 to removed the base residue; drying the washed neutralized epoxidized oil under vacuum; and reacting the washed neutralized dried epoxidized oil with polyhydric alcohol in the presence of boron trifluoride-diethylether complex to produce the oleochemical polyols. The oleochemical polyols are then subjected to the same washing, neutralizing, washing and drying process as in preparing the washed neutralized dried epoxidized oil.

This invention discloses a rapid method of production for fatty acid amide from fatty acid and urea. One example is the preparation of oleylamide from oleic acid and urea. The yields are high and oleylamide is selectively formed by judicious choice of catalyst. The production of fatty acid amide involves heating fatty acid and urea in a microwave oven with the use of Lewis acid catalyst. The product from the reaction is subjected to solvent extraction with chloroform and then followed by purification with n-hexane, ethanol and acetonitrile via recrystalization method. Such an oleylamide is preferred for application as a mould release agent, slip agent in plastic film production, water repellent and as a raw material for cosmetics production.
