Multifunctional additives to improve the low-temperature properties of distillate fuels and compositions thereof
This patent describes a fuel composition comprising a major proportion of a liquid hydrocarbyl fuel and a minor proportion. It comprises about 0.001 wt % to about 10 wt % based on the total weight of the composition of an additive product of reaction obtained by reacting in differing ratios a hydrocarbyl diol or mixture of hydrocarbyl diols and a reactive acid and/or anhydride derived from the reaction of pyromellitic dianhydride of its acid equivalent having hydrocarbyl groups derived from aminoalcohols, derived from secondary amines capped with an olefin oxide, having a combination of hydrocarbyl groups attached thereto and wherein the differing ratios are less than molar ratios, substantially molar ratios and more than molar ratios and; where the temperature of reaction varies from about 150{degrees} C to 200{degrees} C, at pressure of from about 0.001 atm to 1 atm.
