The present invention provides a fuel additive composition for stabilizing blends of ethanol and a hydrocarbon boiling in the gasoline or diesel range, comprising: a) 0.1-10% of Cashew Nut Shell Liquid (CNSL) derivative(s) or mixtures thereof of formula (I) where m=0-12, n=0, 2, 4 & 6 and b) 0.1-10% of an organic co-solvent depending upon the percentage composition of diesel and ethanol blend. 

Fuel additive composition for stabilising blends of ethanol and a hydrocarbon

Phosphorothionate derivatives derived from cashew nut shell liquid (CNSL) for use as an thermally stable antioxidant, antiwear, friction reducing and extreme pressure additive in a lubricant composition are synthesized by the steps of (a) partially hydrogenating distilled technical cashew nut shell liquid with palladium or nickel or platinum catalyst; to hydrogenate the olefinic chain; (b) reacting partially hydrogenated technical cashew nut shell liquid with phosphorus trihalide and sulphur, the reaction being carried out at a temperature ranging from 20 to 220&deg; C. A lubricant containing a major proportion of a material selected from the group consisting of an oil of lubricating viscosity or a grease; and remainder an additive including CNSL phosphorothionate derivative, prepared by the foregoing process.
