Synthesis and study of antistatic diesel additives based on petroleum acids

Various alkyl nitronitrates based on individual olefins and mixtures of propylene trimer and tetramer isomers have been derived. Hydroxyesters have been synthesized via the reaction of natural naphthenic acid with propylene oxide in different molar ratios, as have complexes of chromium, nickel, and cobalt salts of natural naphthenic acids with alkyl nitronitrates. The electric conductivity of 0.001% solutions of nitro compounds in diesel fuels has been examined. It has been found that the antistatic properties of the chromium and nickel salts prevail, with the greatest antistatic effect being displayed by the complexes of the chromium salt. Hydroxyesters in a 1: 1 molar ratio also exhibit a strong antistatic effect.
