The kinetics and transesterification of Sapindus mukorossi seed kernel powder with dimethyl carbonate (DMC) were explored using a mixed KOH-Folch solution as a catalyst for the preparation of biodiesel. The effect of the reaction conditions (the molar ratio of S. mukorossi seed kernel powder with DMC, the catalyst amount and the reaction time, the reaction temperature and the agitation speed) on DMC-Sm-BioDs yields were investigated. The highest DMC-Sm-BioDs yield was 95% at 60 °C for 60 min with a molar ratio of S. mukorossi seed kernel powder to DMC 1:3 and 1.5% KOH (based on DMC weight). DMC-Sm-BioDs was analyzed by gas chromatography-mass spectrometry (GC-MS) to identify the fatty acid dimethyl esters. The activation energy (Ea) was 75.2 kJ mol-1, and the pre-exponential factor was 1.09×108 min-1. The DMC-Sm-BioDs produced from S. mukorossi seed kernel powder is characterized for various properties, such as the kinematic viscosity at 40 °C, the specific gravity at 25 °C, the flash point, the pour point, the cloud point, the acid value and the copper stripe corrosion. DMC-Sm-BioDs satisfied the European quality standards defined in ASTM D6751-02. © 2015 Taylor & Francis.

The transesterification of Pongamia pinnata seed oil with dimethyl carbonate (DMC) for preparing DMC-BioD has been studied at the catalysis of potassium hydroxide (KOH). The effects of reaction conditions (ratio of P. pinnata seed oil and DMC, catalyst amount and reaction time, reaction temperature and agitation speed) on DMC-BioD yield were investigated. The highest DMC-BioD yield could reach 96% at refluxing temperat ure for 6 h with ratio of P. pinnata oil to DMC 1:3 w/w and 4% KOH (based on oil weight). Percentage of conversion has been analyzed by Gas Chromatography. P. pinnata seed oil DMC-BioD produced is characterized for the properties such as the kinematic viscosity at 40°C, density at 25°C, flash point (FP), pour point (PP), cloud point (CP), acid value and copper strip corrosion. P. pinnata seed oil DMC-BioD produced met with the quality standards defined under ASTM D675-02. © 2013 Elsevier Ltd. All rights reserved.
