Summary: The object of the study is the process of chemical transesterification of sunflower oil. Liquid vegetable oils are an important component in the products of chemical, cosmetic, paint, food and other industries. Among other oils, sunflower oil is of exceptional indus- trial importance. Chemical transesterification tech- nology is used to obtain oils, fats and their mixtures with specified proper- ties required for various industries. An important task is to develop ratio- nal conditions for the oil transesterifi- cation process using a highly efficient and safe catalyst. The process of chemical transester- ification of refined deodorized frozen sunflower oil according to DSTU 4492 (CAS Number 8001-21-6) using potas- sium glyceroxide was studied. The original oil has the following parame- ters: peroxide value 0.2 ½ O mmol/kg, acid value 0.1 mg KOH/g, moisture mass fraction 0.03 %, crystallization temperature –18.38 °С. The effect of transesterification parameters on the oil crystallization temperature was examined. The cat- alyst concentration in all experiments was 0.45 % by weight of the oil. The oil crystallization temperature was deter- mined by differential scanning calo- rimetry. Rational parameters of oil transesterification were defined: tem- perature 110 °C, duration 1.5 hours. Under these conditions, there is a max- imum increase in the oil crystalliza- tion temperature (up to –4.1 °С). The effectiveness of the rational oil trans- esterification parameters was con- firmed by changes in the triglycer- ide composition by chromatography analysis. The obtained rational condi- tions for the chemical transesterifica- tion of sunflower oil in the presence of the potassium glyceroxide catalyst can also be used in the processes of oil transesterification with other raw materials using this catalyst.
