FIELD: chemistry.
SUBSTANCE: invention relates to use of alkylphenol-aldehyde resins and nitrogen-containing polymers in improving electroconductivity of oil distillates with low water content and to oil distillates with additives. The invention discloses oil distillates with water content less than 150 pts/mln and electroconductivity of not less than 50 pS/m, containing at least one alkylphenol-aldehyde resin in amount of 0.1-200 pts/mln and at least one nitrogen-containing polymer in amount of 0.1-200 pts/mln, selected from a) comb-like polymers containing units formed from C4-C40 alkyl monomers and at least one nitrogen-containing comonomer, b) copolymers of ethylene with unsaturated ethylene and nitrogen-containing comonomers, c) polymeric polyamines obtained via condensation of the aliphatic primary monoamine or N-alkyl-alkylenediamine with epichlorohydrin or glycidol. The invention also discloses versions of the method of improving electroconductivity of oil distillates, additives for oil distillates, as well as use of the alkylphenol-aldehyde resin and composition based on said resin in improving electroconductivity of oil distillates.
EFFECT: additives which are efficient at low temperatures and also improve low-temperature fluidity of fuel distillates.
