Abstract
This invention relates to petroleum fuel compositions with improved haze properties, said fuel composition containing an anti-haze additive comprising an hydroxylated resin acid and/or a selected metal resinate salt.
Claims25
A fuel composition comprising a major amount of gasoline and from about 1 to about 30 ppm by weight of an anti-haze additive selected from the group consisting of an hydroxylated resin acid and a metal resinate salt wherein said metal is selected from the metals of Group II to IV, VII and VIII of the Mendeleev periodic table.
A fuel composition comprising a major amount of gasoline and an effective dehazing amount of an hydroxylated resin acid anti-haze additive.
The composition of 19 wherein said metal resinate salt is a mixture of zinc and calcium resinate salts.
A method of removing or reducing the haze formation in gasoline comprising adding from about 1 to about 30 ppm by weight of an anti-haze additive selected from the group consisting of an hydroxylated resin acid and a metal resinate salt wherein said metal is selected from the metals of Group II to IV, VII and VIII of the Mendeleev periodic table.
A method of removing or reducing the haze formation in gasoline comprising adding an effective dehazing amount of an hydroxylated resin acid anti-haze additive.
