An alkali-catalyzed biodiesel production method with power ultrasonic (19.7 kHz) has been developed that allows a short reaction time and high yield because of emulsification and cavitation of the liquid-liquid immiscible system. Orthogonality experiments were employed to evaluate the effects of synthesis parameters. Furthermore, hydrodynamic cavitation was used for biodiesel production in comparison to ultrasonic method. Both methods were proved to be efficient, and time and energy saving for the preparation of biodiesel by transesterification of soybean oil.
已开发出一种采用功率超声（19.7kHz）的碱催化生物柴油生产方法，由于液 - 液不混溶体系的乳化和空化作用，该方法具有反应时间短、产率高的特点。采用正交实验来评估合成参数的影响。此外，与超声方法相比，利用水力空化进行生物柴油生产。两种方法均被证明是高效的，且在通过大豆油酯交换制备生物柴油方面节省时间和能源。
