Abstract: This paper is about water removal from vegetable oil. Commonly, used drying methods are expensive. Oil dried for transesterification yields improvement and side reaction suppression. Water promotes an undesirable side reaction—saponification of oil. Drying was performed at different pressures and with various additions of alcohol as methanol, ethanol and butanol. The experiment shows that addition of just a small amount of alcohol during vacuum distillation decreased water content to 50 ppm.

Keywords: Vegetable oil ; Alcohol ; Water removal ; Moisture ; Azeotrope
