The hydrolysis of rubber seed oil in sub-critical water without any catalyst and its reaction kinetics were researched. The rubber seed oil was hydrolyzed in a high pressure and high temperature batch type reactor. The results show that the highest yield of fatty acids is 96.2% at 280 ℃, 15 MPa, and reaction time 40 min with a volume ratio 3: 1 of water to oil (mole ratio 162: 1). The kinetics calculation indicates that the reaction order and activation energy of rubber seed oil hydrolysis in sub-critical water is 1.4 and 43.5 kJ/mol, respectively. The research provides a theoretical basis for the kinetics of oil hydrolysis in two-step preparation for biodiesel fuel.
