| 摘要 |
This invention describes the preparation of fatty acid esters of glycerol formal either by a triglyceride transesterification process or, alternative ly, by an esterification process of fatty acids previously obtained from the hydrolysis of triglycerides (fat splitting), with glycerol formal in the pr esence of an acid or basic catalyst. Also the invention describes the use of these fatty acid esters of glycerol formal prepared by said process as biof uel. In an embodiment, such biofuel is used in the preparation of other biof uels by its mixture with a product selected from a group formed by: glycerol formal, biodiesel, petrol-derived diesel, and mixtures thereof. The biofuel s thus obtained are characterised to allow the complete incorporation of the glycerol obtained in the current biodiesel production process in a biodiese l fuel.
