In this study, using a power law approximation, the reaction orders of dolomite catalyzed transesterification of canola oil and methanol were evaluated. The reaction orders for triglyceride and methanol were determined as 1 and − 1.2 respectively, with a 0.9182 correlation coefficient. The rate constant was calculated as 3.9579 × 10− 3 (lt− 0.2/mol− 1.2). (gr.− 1 cat. min− 1) for this correlation. The reaction order of triglyceride which appeared in nominator of rate equation was considered as driving force of the reaction. The negative reaction order of methanol indicates the adsorption of methanol on the catalyst surface.
► Using a power law approximation, the reaction orders were determined.
► Triglyceride concentration acts as driving force for the reaction.
► A good correlation was obtained between experimental and calculated rate values.
