Abstract (en)
[origin: EP1801187A2] Use of at least an oil-soluble polyoxy alkylene compound comprising an oil soluble, amphiphilic compound containing at least a 10-500C- alkyl or alkenyl and a polar group with two or more nitrogen atoms for improving the cold flow characteristic of mineral oil in a distillating agent containing at least an ash free, a detergent additive containing nitrogen, where the oil-soluble polyoxy alkylene compound is e.g. an oil soluble ester, ether, ether/ester of alkoxylated polyol. Use of at least an oil-soluble polyoxy alkylene compound comprising an oil soluble, amphiphilic compound containing at least a 10-500C- alkyl or alkenyl and a polar group with two or more nitrogen atoms for improving the cold flow characteristic of mineral oil in a distillating agent containing at least an ash free, a detergent additive containing nitrogen, where the oil-soluble polyoxy alkylene compound is an oil soluble ester, ether, ether/ester of alkoxylated polyol with at least three 2-5C-alkylene oxide and polyol containing repetitive alkoxy per hydroxy group or at least two aliphatic 12-30C-hydrocarbon. Independent claims are included for: (1) a composition comprising at least an ash free, detergent additive containing nitrogen, which is an oil soluble, amphiphilic compound containing at least a 10-500C- alkyl- or alkenyl with two or more nitrogen atoms bonded to a polar group, and at least an oil soluble polyoxy alkylene compound, which is an oil soluble ester, ether or ether/ester of alkoxylated polyol with at least three 2-5C-alkylene oxide, and repetitive alkoxy per hydroxyl group; and (2) a distillative agent with a sulfur content of less than 100 ppm and 20-90 vol.% of agent exhibits a distillative boiling range of less than 120[deg]C, comprising the composition (10-10000 ppm) and at least a mineral oil cold flow improver.
