Abstract (en)
[origin: EP1749873A2] A mineral oil distillate having a water content of less than 150 ppm and a conductivity of at least 50 pS/m, comprises 0.1-200 ppm at least one alkylphenolaldehyde resin and 0.1-200 ppm at least one nitrogen-containing polymer. Independent claims are also included for the following: (1) improving the electrical conductivity of mineral oil distillates having a water content of less than 150 ppm and comprising 0.1-200 ppm nitrogen-containing polymer(s), by adding to the mineral oil distillates compositions comprising 0.1-200 ppm alkylphenol-aldehyde resin(s) and, based on the alkylphenol-aldehyde resin, 0.1-10 pbw nitrogen-containing polymer(s) so that the mineral oil distillates have a conductivity of at least 50 pS/m; and (2) an additive for mineral oil distillates comprising alkylphenol-aldehyde resin(s) and nitrogen-containing polymer (s) from a comb polymer containing units derived from esters of ethylenically unsaturated carboxylic acids, vinyl esters, and/or vinyl ethers, and nitrogen-containing comonomer(s); a copolymer of ethylene with an ethylenically unsaturated nitrogen-containing comonomer; and a polymeric polyamine, prepared by condensation of an aliphatic primary monoamine or of an N-alkylalkylene-diamine with epichlorohydrin or glycidol.
