Abstract: Jatropha Curcas oil was used as feedstock for producing biodiesel by transesterification，and adding sodium hydroxide，potassium hydroxide or sodium methoxide as catalyst respectively. The optimal conditions were obtained：molar ratio of methanol to oil 6∶1，reaction temperature 60 ℃，reaction time 80 min，mixing intensity 600 r/min，catalyst concentration for NaOH，KOH，or CH3ONa 1.2% of oil weight，The yield of biodiesel was above 97% . The physico-chemical indices of the biodiesel obtained met the quality standard ASTM of USA and DIN V of Germany. Through the preliminary analysis of economic benefits，by using non-edible Jatropha Curcas oil as raw material based on the whole industrial chain of the cultivation of Jatropha Curcas，the raw material cost is low，and the economic benefits are significant. It has also the advantage of not contending for land with grain.

摘要： 选用了非食用油麻疯果油为原料，以氢氧化钠、氢氧化钾、甲醇钠为催化剂，通过酯交换法制取生物柴油，研究表明最适宜工艺条件为：醇油比6∶1，反应温度60 ℃，反应时间80 min，搅拌强度为600 r/min，催化剂用量为1.2%，转化率达到97%以上，且生物柴油各项理化指标均符合美国和德国测试标准。且从麻疯果的种植到生物柴油的生产整个产业链出发，其原料成本更低，经济效益更大，体现了不与粮争地的优势。
