 · The crude soap obtained from the saponification reaction contains sodium chloride, sodium hydroxide, and glycerol. These impurities are removed by boiling the crude soap curds in water and re-precipitating the soap with salt. After the purification process is repeated several times, the soap may be used as an inexpensive industrial cleanser. A process for preparing polyol fatty acid polyesters having levels of triglyceride below 0.5% is described. Methyl esters having a level of monoglycerides below 500 ppm, a nondetectable level of di- and triglyceride and a glycerine level of less than about 200 ppm are prepared and then used in a two-stage, solvent-free transesterification reaction to prepare the polyol fatty acid polyesters.

The influence of the palm kernel oil based polyester polyol content on reaction kinetics, structure, morphology and mechanical properties of rigid polyurethane foam were evaluated by cup test ... Cost of biodiesel produced from vegetable oil through transesterification is higher than that of fossil fuel, because of high raw material cost. To minimize the biofuel cost, in recent days waste cooking oil was used as feedstock. Catalysts used in this process are usually acids, base, and lipase. Since lipase catalysts are much expensive, the usage of lipase in biodiesel production is ...
