摘　　要：在管道式条件下,采用丁酮为共溶剂进行连续甲酯化制备生物柴油的中试实验。根据实验数据和设备固有参数分别推导出了转化率与反应时间的关系以及转化率与进料流量的关系。在不改动设备的前提上,为了达到较为满意的转化率,最有效方法就是提高共溶性和增加循环次数延长反应时间。且实际转化率与时间的关系为:Y=99.5-157.83591×EXP(-0.60508×(t/8))。除为生产提供了理论依托和估计反应程度外,也方便了操作流程,降低了操作的盲目性。Under the condition of tubular mixer,a continuous process for biodiesel synthesis with butanone as co-solvent was studied in this paper.According to the experimental data and the inherent parameters of equipment,the relationship for the reaction time and feeding flux with conversion rate were deduced.Without any changes made to the equipment,the most effective approach for a more satisfactory conversion rate is to improve solubility and extend of reaction time.The actual relationship between conversion rate and the time is：Y=99.5-157.83591×EXP（-0.60508×（t/8））.It provides a theoretical basis for production,also facilitates the operation process,and reduces the blindness of operation.
