摘要
介绍了在碱催化剂作用下以葵花籽油与甲醇反应生成生物柴油的工艺条件,考察了醇油摩尔比、催化剂用量、反应温度、反应时间等条件对反应的影响,采用正交实验的方法得出最佳的反应条件:醇油摩尔比6:1、催化剂用量0．9％、反应温度60℃、反应时间50 min。对所得到生物柴油的主要性能与柴油进行对比,其指标均符合0#矿物柴油标准。
The technical terms of producing biodiesel by sunflower seeds oil through esterfication with methanol under the catalyzer of alkali are investigated. Through orthogonal analysis, the optimum conditions are obtained as follaws： the molar ratio of methanol to oil 6：1, usage amount of catalyst 0.9 %, reaction temperature 60℃ and reaction time 50 min, Compared with diesel oil, main properties of biodiesel are shown to be well confirmed to that of No. 0 mineral diesel oil.
