Abstract:
1. A method for improving the electrical conductivity of a mineral oil distillate having a water content of less than 150 ppm, the mineral oil distillate being selected from the group consisting of jet fuel, gasoline, kerosene, diesel oil, heating oil, the mineral oil distillate having an electrical conductivity of below 10 pS/m, wherein the method comprises the step of adding to the mineral oil distillate a composition which comprises at least one alkylphenol-aldehyde resin (constituent I) which has a structural element of the formula in which R 5 is C 1 -C 200 -alkyl or C 2 -C 200 -alkenyl, O—R 6 or O—C(O)—R 6 , R 6 is C 1 -C 200 -alkyl or C 2 -C 200 -alkenyl, and n is from 2 to 100, and, from 0.1 to 10 parts by weight of at least one polar oil-soluble nitrogen compound (constituent II), based on the alkylphenol-aldehyde resin in such an amount that the mineral oil distillate has a conductivity of at least 50 pS/m.
