The present invention relates to a process for producing oligomers and a method for improving the low temperature properties of fatty alkyl esters by using these oligomers. The oligomers according to the present invention are used as pour point depressant and cloud point reducer to improve the pour point and cloud point of fatty alkyl esters such as isopropyl, butyl, ethyl, ethylhexyl esters particularly fatty acid methyl esters at low temperature.

The present invention relates to a process for reducing color of a polyglycerol. The process includes the steps of treating said polyglycerol with a first bleaching agent such as bleaching earth and treating said treated polyglycerol with a second bleaching agent such as hydrogen peroxide.

Process for reducing color of a polyglycerol

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.
