TY - JOUR AB - Glycerol is a by-product obtained during the production of biodiesel. An increase in biodiesel production would decrease the market price of glycerol. The objective of this study was to investigate glycerol purification, esterification of glycerol by propionic acid and the field of application of the product. Crude glycerol from a Hungarian biodiesel factory was partly refined, soaps, water, methanol and pigments were removed and glycerol still containing inorganic salts was used for certain esterification reactions. A cost effective process for utilization of crude glycerol was created, which can be applied not only for tripropionin production but preparation of other glycerol esters like glyceryl triacetate, glyceryl tributyrate. Moreover, effect of tripropionin blending on engine performance characteristics and environmental repercussions were studied.
