生质柴油为重要之可再生能源。本文研究改善液相触媒制程,以降低甲醇与三酸甘油酯间界面阻力,以提生反应速率。实验结果发现,在批式制程中,提高搅拌速率可提升反应速率,然因工厂实际操作恐有困难。以相转移触媒可达增加反应速率与产率效果,但需注意选用之相转移触媒不可在强碱下被破坏。使用共溶剂THF可促进反应速率与产率,为一可行的选择。而连续制程较批式制程有较好的效率。 Biodiesel is an important renewable energy source. This paper studies to improve the liquid catalyst process to reduce the methanol and triglyceride interfacial resistance in order to induce reaction rate. The experimental results show that in the batch process, increasing the stirring rate can improve the reaction rate, but due to the actual operation of the plant may be difficult. To phase transfer catalyst up to increase the reaction rate and yield effects, but be careful that the selection of the phase transfer catalyst can not be destroyed in a strong base. The use of cosolvent THF can promote the reaction rate and yield, as a viable option. The continuous process than batch process has good efficiency.
