IMPROVED ADDITIVE CONCENTRATES FOR DISTILLATE FUELS

摘要

An additive concentrate for incorporation into wax containing petroleum fuel oil compositions to improve low temperature flow properties comprising an oil solution containing: (a) 3% to 90 wt. % of a C30-C300 oil-soluble nitrogen compound wax crystal growth inhibitor having at least one straight C8-C40 alkyl chain and partial esters, and (b) at least one mole per mole of (a) of an organic acid capable of hydrogen bonding with (a) to improve the solubility of (a) in the oil.
