【摘要】 以桐油和甲醇为原料,在催化剂KOH作用下,经酯交换反应制得生物柴油。考察了醇油比、催化剂用量、反应温度、反应时间等条件对转化率的影响。通过设计正交试验筛选反应优化条件,结果表明:当醇油比为6︰1,催化剂用量为1.2%,反应温度为65℃,反应时间为75min,桐油的转化率可达90.5%。更多还原

【Abstract】 In this paper,biodiesel was prepared by transesterification of tung oil with methanol ,using KOH as catalyst.The effect of molar ratio of methanol to tung oil, as well as the amount of catalyst, reaction time, and temperature on biodiesel production was investigated. Through orthogonal test analysis of parameters, the optimum conditions for transesterification were molar ratio of methanol to oil 6:1,usage amount of KOH 1.2%(based on the oil weight), reaction temperature 65℃, and reaction time 75 min. Under these conditions, tung oil led to a 90.5% conversion.更多还原
