| Abstract: | The hydrolysis of rubber seed oil catalyzed by acid was studied.The effect of reaction temperature,time,catalyst amount,ratio of oil to water and emulsifier amount on hydrolysis were studied.The optimum reaction conditions,which could increase the acid value of hydrolysis product to 189.41 mg KOH/g and the conversion of rubber seed oil to fatty acid was 94.71%,were 95 ℃,10% H2SO4(98%),1∶2 oil to water ratio(by weight),1% sodium lauryl sulfonate used as emulsifier after 9 h of reaction time. |
