【摘要】 实验研究了乙醇钠催化下橡胶籽油与乙醇进行酯交换反应制备生物柴油的工艺条件。通过正交实验和单因素实验,发现酯交换反应的最佳工艺条件:催化剂用量为油重的1.0%,醇油物质的量比为15∶1,反应温度为78℃,搅拌时间为120 min,在此反应条件下,橡胶籽油转化率为92.14%。更多还原

【Abstract】 The technology for biodiesel production with rubber seed oil as feedstock was studied by orthogonal test and single factor experiment.The result indicated that the optimal conditions for transesterfication of rubber seed oil were as follows: 1.0% C2H5ONa of rubber seed oil in weight,the mole rate of ethanol to oil was 15∶1,the reaction temperature was 78 ℃,the reaction time was 120 min.The 92.14% transesterification rate has been obtained under the optimal conditions.更多还原
