Abstract: 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.

Abstract: The present invention relates a surfactant composition for use as an emulsifier in water blended fuel mixture. The said composition includes ethoxylate of cashew nut shell liquid. In addition ethoxylate of cashew nut shell liquid, the said composition comprises a co-surfactant having a hydrophilic lipophilic balance in the range of 4 to 12 and a polymeric dispersant. The water blended fuel mixture using emulsifiers of the present invention, overcome some of the shortcomings of the previously known emulsions. The ethoxylate of cashew nut shell liquid is of the formula (I).

Abstract: A lubricating oil composition for gasoline and diesel internal combustion engines includes a major portion of an oil of lubricating viscosity; from 0.1 to 20.0% w/w of a component A which is a sulfurized, overbased calcium phenate detergent derived from distilled, hydrogenated cashew nut shell liquid; and from 0.1 to 10.

Abstract: Magnesium borate overbased metallic detergent having magnesium borate uniformally dispersed in an extremely fine particle size is prepared by using magnesium alkoxide and boric acid. The process for preparation involves reacting neutral sulphonate of an alkaline earth metal with magnesium alkoxide and boric acid under anhydrous conditions in the presence of a dilution solvent followed by distillation to remove alcohol and part of dilution solvent therefrom. The borated mixture is then cooled, filtered to recover magnesium borated metal detergent. The magnesium borated metal detergent exhibited excellent cleaning and dispersing performance, very good hydrolytic and oxidation stability, good extreme pressure and antiwear properties. Such a detergent can advantageously be used in a hydrocarbon composition.
