Biodiesel fuel has become more attractive recently because of its environmental benefits and the fact that it is a product made from renewable resources. However the less favorable cold flow properties or the low temperature operability of biodiesel fuel compared to conventional diesel is a major drawback limiting its use.

This study is to clarify the pathways of the transesterification of vegetable oil by applying NMR to the identification of intermediates in the transesterification reaction. Results showed that the significant methanolysis product was sn-1,3-diglycerides in diglycerides, and sn-2-monoglycerides was not found. These analytical results suggest that the methanolysis reaction may occur easily at the sn-2-position...
