MINERAL OILS WHICH COMPRISE DETERGENT ADDITIVES AND HAVE IMPROVED COLD FLOWABILITY

摘要

Mineral oils which comprise detergent additives and have improved cold flowability The invention provides for the use of at least one oil-soluble polyoxyalkyle ne compound, this polyoxyalkylene compound being an oil-soluble ester, ether or ether/est er of alkoxylated polyols having at least three repeat alkoxy units derived from alkylene oxides having from 2 to 5 carbon atoms per OH group of the polyol which bear s at least two aliphatic hydrocarbon radicals having from 12 to 30 carbon atoms for improving the response behavior of mineral oil cold flow improvers in middle distillates which comprise at least one ashless, nitrogen-containing deterge nt additive which is an oil-soluble amphiphilic compound which comprises at least one alkyl or alkenyl radical which is bonded to a polar group, the alkyl or alkenyl radic al comprising from 10 to 500 carbon atoms and the polar group comprising 2 or more nitrogen atoms.
