摘要
本研究旨在确定德国毛毛虫(Zophobas morio L)使用H2SO4催化剂进行直接转化的方法的最佳反应时间。在两种不同的情况下,反应时间为8、12、16和20小时(比较n-heksana甲醇1:2和1:5)。这项研究的结果表明,在这两种情况下都没有找到最佳时机。发现最具潜力的生物柴油产品符合三种标准的生物柴油参数中的两种,即反应时间为20小时,产生20mL的生物柴油,密度为0.8950 g / 1,粘性性为1217 cSt,酸性为0.41 mg KOH/g样本。根据生物柴油的GC-MS测试,它最有潜力获得四种甲基苯甲酸、甲基苯甲酸、甲基苯甲酸和甲醇甲醇。关键词:生物柴油、甲基酯、直接转化化,德国毛毛虫将这一研究中的生物柴油的最佳反应时间用于确定从超级蠕虫(Zophobas morio L)使用直接倒置方法H2SO4。《泰晤士报》8、12、16和20小时进行调查。这项研究的结果还没有在两者条件下找到最佳时机。大多数潜在的雾》是找到那个生物柴油产品已经能实现二》三标准生物柴油parameters,雾》是那么可怜hexane-methanol 1:5 solvents with a的反应时间20小时producing 20毫升的生物柴油,密度0。8950 g mL-1 kinematic cSt viscosity 12 . 17号,和酸0.41 mg KOH - g样品。gc

Abstract
The aims for this studies was to determine the optimum reaction time of biodiesel from superworm (Zophobas morio L.) using H2SO4 catalyst by direct transesterification method. Reaction times 8, 12, 16, and 20 hours in two different conditions (comparison of hexane-methanol solvents 1:2 and 1:5) were investigated. The results of this study have not yet found optimal time in both conditions. It was found that the most potential condition of biodiesel products had fulfilled two of the three standard biodiesel parameters, was the condition of the comparison of hexane-methanol 1:5 solvents with a reaction time of 20 hours producing 20 mL biodiesel, density 0.8950 g mL-1, kinematic viscosity 12.17 cSt, and acid number 0,41 mg KOH/g sample. The GC-MS result showed the methyl ester from biodiesel product are contains methyl palmitate, methyl palmitoleate, methyl linoleic, and methyl stearat
