Abstract

Hydrolysis of kapok seed oil in the presence of hydrochloric acid catalyst to produce glycerol and fatty acid was studied. The objective of this work was to study the effect of reaction temperature and catalyst concentration on the reaction rate constant. The experiments were conducted in a three-neck flask equiped with stirrer, heater, condenser, and thermometer. The reaction condition studied were temperature ranging from 80 to 100 °C and catalyst concentration from 0.011 to 0.017 N. The reaction time was kept constant at 3 hours. The concentration of triglycerides every 0.25 hour were analyzed to calculate the conversion of triglycerides. The results of this study showed that the reaction kinetics of the hydrolysis of kapok seed oil was found to be first order with respect to triglyceride. The effect of reaction temperatures on the reaction rate constant was found to be k = 0.3258 exp(−1379.8875/RT) h−1, the activation energy was 1379.8875 cal/mol and the effect of catalyst concentrations on the reaction rate constant could be expressed as k = 0.06002 exp(−0.0025/Ck) h−1.
