TRANSESTERIFICATION OF TRIGLYCERIDES OF VEGETABLE OIL WITH METHANOL UNDER HETEROGENEOUS CATALYSIS CALCIUM AND MAGNESIUM OXIDES
Abstract
The aim of this work was to study the reactions of methanolysis of triglycerides of vegetable
oils (coconut, palm, sunflower and soy) using heterogeneous basic catalysts — calcium and
magnesium oxides in mild conditions. Preliminary preparation of catalysts was maintaining calcium
hydroxide and magnesium nitrate at various temperatures (600, 800, and 1000 °C) for 1 hour. Calcium
oxide exhibits the maximum effectiveness as a heterogeneous catalyst in reactions methanolysis
of vegetable oils, obtained by calcining at 800 °C in an amount of 0.5—0.7 % by weight of the
oil load. The reaction time is 2—4 hours at 70 °C.
