The esterification of myristic acid with methanol in presence of triglycerides using sulfated zirconia prepared by solvent-free method as the heterogeneous catalyst was studied. The effects of reaction temperature (393–443 K), catalyst loading (1–3 %wt) and molar ratio of oil to methanol (1:4–1:20) on the conversion of myristic acid were investigated. The experimental data was interpreted with a second order pseudo-homogeneous kinetic model. The kinetic parameters were obtained. A good agreement between the experimental data and the model was observed. Sulfated zirconia prepared by solvent-free method exhibited high catalytic activity for this reaction. Low activation energy of 22.51 kJ mol−1 was obtained in the range of temperature of 393–443 K.
► Sulfated zirconia uses as catalyst for esterification of myristic acid in rapeseed oil. ► A pseudo-homogeneous model shows good agreement with the experimental data. ► High catalytic activity of this catalyst results in a very low activation energy.
