Mineralöle mit verbesserter Leitfähigkeit und Kältefliessfähigkeit

摘要

A mineral oil composition comprises at least one alkylphenolaldehyde resin and, based on the alkylphenol resin, 0.05-10 wt.% of at least one salt of an aromatic base and of a sulfonic acid. Independent claims are also included for: (1) mineral oil distillate having a conductivity of more than 50 pS/m, which comprises the above composition, or having an aromatics content of less than 25 wt.% and comprising 5-5000 ppm of the above composition; (2) improving the electrical conductivity of a mineral oil distillate having an aromatics content of less than 25 wt.%, comprising adding at least a portion of the composition to the mineral distillate to provide the mineral oil with improved electrical conductivity; and (3) improving the cold flowability of a mineral oil distillate having a sulfur content less than 350 ppm, comprising adding to the mineral oil distillate the above composition.
