Abstract
An additive for inhibiting sedimentation and retarding degradation of hydrocarbon oils as evidenced by discoloration comprises the reaction product of an alkoxyalkylamine with an epihalohydrin at a temperature from about 40.degree. C. to about 150.degree. C. in the presence of an inorganic base.
Claims13
A composition comprising a major amount of a hydrocarbon oil containing from about 0.0001% to about 1% of the reaction product of 1 molar proportion of an alkoxyalkylamine, wherein said amine is a primary amine, said alkoxy group contains from about 1 to about 25 carbon atoms, and said alkyl group is an alkylene containing 2 to about 10 carbon atoms, with about 0.5 to about 2.0 molar proportions of an epihalohydrin selected from the group consisting of epihalohydrin, 1-halo-3,4-epoxybutane, 1-halo-2,3-epoxybutane, 1-halo-4,5-epoxypentane, and 1-halo-3,4-epoxypentane, at a temperature from about 40.degree. C. to about 150.degree. C. in the presence of an inorganic base.
A method of inhibiting sedimentation and discoloration of hydrocarbon oils comprising dissolving therein an amount from about 0.0001% to about 1% of the reaction product of 1 molar proportion of an alkoxyalkylamine, wherein said amine is a primary amine, said alkoxy group contains from about 1 to about 25 carbon atoms, and said alkyl group is an alkylene group containing 2 to about 10 carbon atoms, with about 0.5 to about 2.0 molar proportions of an epihalohydrin selected from the group consisting of epihalohydrin 1-halo-3,4-epoxybutane, 1-halo-2,3-epoxybutane, 1-halo-4,5-epoxypentane, and 1-halo-3,4-epoxypentane, at a temperature from about 40.degree. C. to about 150.degree. C. in the presence of an inorganic base.
