“…Corro et al [17] reported a novel esterification treatment under solar radiation with Zn filings as solid catalyst followed by base-transesterification indicating AV was reduced from 18.5 to 0.38 mg KOH/g. Worapun et al [24] reported the two step catalyzed transesterification process coupled with UI at room temperature and reported 98% of conversion to biodiesel. Boffito et al [3] reported a biodiesel yield higher than 90% by ultrasound-assisted batch transesterification with pulsed UI performed in rosett cell reactor with a reaction time 15 times faster than classic mechanical stirred process.…”

In this present work, biodiesel was produced from mahua oil (Madhuca indica) having high free fatty acids through a two step esterification and transesterification process. The first step was carried out with 0.35% mol/mol methanol to oil ratio, 1% v/v sulphuric acid and one hour reaction time at 50 C in a 1000 mL reactor. In the second step the mixture was transesterified with 1.5% mol/mol methanol to oil ratio and 0.75% v/v KOH, one hour reaction time at 50 C. The process was repeated with ultrasonic power of 1000W, 20À30 Hz frequency and five minutes reaction time. The fuel properties of MOME (mahua oil methyl ester) including acid value, density, viscosity, iodine value, flash and fire point, cloud and pour point, and calorific value obtained from both methods were compared with ASTM 2003 standards. Biodiesel produced from ultrasonic transesterification is economically viable and more efficient than that produced by the conventional method. Therefore it is concluded that the ultrasonic method is an effective way of converting crude mahua oil into biodiesel.

Summary Ultrasound‐assisted biodiesel production is an emerging technology that features high energy density, high conversion efficiency, and environment friendliness. This review evaluates the influence of process parameters, including ultrasonic power, ultrasonic frequency, catalyst dosage, alcohol/oil ratio, reaction temperature, reaction time, and alcohol type, on the yield of ultrasonic‐assisted production of biodiesel. Limitations associated with ultrasonic‐assisted production of biodiesel are also analyzed. Further development of this technology is explored. Copyright © 2016 John Wiley & Sons, Ltd.
