摘要

Transesterification of crude cottonseed oil with methanol in the presence of base catalyst by means of low-frequency ultrasonic irradiation at room temperature was investigated to evaluate the effects of reaction time, molar ratio of methanol to oil, catalyst type, and catalyst concentration on the biodiesel yield. All the catalysts exhibited better activity at 6/1 molar ratio of methanol to oil, among which potassium methoxide demonstrated the best activity. In addition, the effect of ultrasonic frequency on the biodiesel yield was also assessed. The high yield for the crude cottonseed oil biodiesel under the ultrasonic irradiation condition was attributed to the efficacy of cavitation, which could enhance the mass transfer between the methanol and crude cottonseed oil. The present results confirmed the high efficiency and feasibility of using ultrasonic energy to produce biodiesel.
