A safe, convenient, and environmentally benign laboratory experiment for the synthesis of biodiesel from six kinds of vegetable oils has been developed for the introductory organic chemistry laboratory. The experiment uses ultrasonic irradiation in the presence of a base catalyst at room temperature and atmospheric pressure. Because of safer and greener conditions, shorter reaction time and separation time, high purity (close to 100%) and high yields, and lower generation of waste or pollutants, this experiment is a good example to introduce students to the Twelve Principles of Green Chemistry as well as important organic chemistry concepts and techniques. Moreover, a low-cost ultrasonic cleaner is used as the ultrasonic irradiation source in the experiment, which allows the project to be widely implemented in high-school- and college-level laboratory curricula.

超声波辅助酯交换反应：绿色小型有机实验室实验

已为有机化学入门实验室开发了一种安全，方便且对环境有益的实验室实验，用于从六种植物油中合成生物柴油。该实验在室温和大气压下在碱催化剂存在下使用超声辐射。由于更安全，更环保的条件，更短的反应时间和分离时间，高纯度（接近100％）和高收率以及废物或污染物的产生减少，该实验是向学生介绍绿色化学十二个原理的好例子以及重要的有机化学概念和技术。另外，在实验中，使用低成本的超声波清洗机作为超声波照射源，
