Esters of castor oil and hydrogenated castor oil were prepared with C 6 , C 12 , C 16 , C 18 fatty acids, using tetra‐ n ‐butyl titanate as a catalyst and n ‐butyl benzene as a water entrainer. Physical properties such as melting point, refractive index, viscosity, and specific gravity of these esters were measured. Slip melting points of the esters were very low in both cases. These esters did not crystallize even at low temperature. The highest slip melting point obtained was 21 °C with stearoyl hydrogenated castor oil ester and lowest slip melting point obtained was —6 °C with hexanoyl castor oil ester.
