Claims6
A gelled hydrocarbon composition comprising a liquid hydrocarbon, a partial aluminum salt of an alkyl acid ortho-phosphate, said partial aluminum salt hving a P/Al ratio in the range of from 2.86/1 to about 10/1, said alkyl acid ortho-phosphate being a mixture of a monoalkyl diacid orthophosphate and dialkyl monoacid orthophosphate wherein the alkyl groups comprise a mixture of at least one C.sub.1 to C.sub.5 alkyl radical and at least one radical selected from the group consisting of C.sub.6 to C.sub.22 alkyl radicals and C.sub.6 to C.sub.22 alkenyl radicals, and a neutralizing amount of a polyamine compound selected from the group consisting of ethylene diamine, diethylene triamine, triethylene tetramine, tetraethylene pentamine, polyfunctional aromatic amines, and mixtures thereof.
A method of making a gelled hydrocarbon composition comprising the steps of dispersing from 0.1 to 10 parts by weight of a partial aluminum salt of an alkyl acid orthophosphate having a P/Al ratio in the range 2.86/1 to about 10/1, said alkyl acid orthophosphate being a mixture of a monoalkyl diacid orthophosphate and a dialkyl monoacid orthophosphate wherein the alkyl groups comprise a mixture of at least one C.sub.1 to C.sub.5 alkyl radical and at least one radical selected from the group consisting of C.sub.6 to C.sub.22 alkyl radicals and C.sub.6 to C.sub.22 alkenyl radicals, and a neutralizing amount of a polyamine selected from the group consisting of ethylene diamine, diethylene triamine, triethylene tetramine, tetraethylene pentamine, polyfunctional aromatic amines, and mixtures thereof.
