Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
122 words
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 1 to C 5 alkyl radical and at least one radical selected from the group consisting of C 6 to C 22 alkyl radicals and C 6 to C 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.
Claim 2
Dependent Claim
122 words
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 1 to C 5 alkyl radical and at least one radical selected from the group consisting of C 6 to C 22 alkyl radicals and C 6 to C 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.
Claim 3
Dependent Claim
18 words
The composition of claim 1 further comprising an epoxy resin and a curing amount of an aromatic diamine.
Claim 4
Independent Claim
129 words
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 1 to C 5 alkyl radical and at least one radical selected from the group consisting of C 6 to C 22 alkyl radicals and C 6 to C 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.
Claim 5
Independent Claim
129 words
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 1 to C 5 alkyl radical and at least one radical selected from the group consisting of C 6 to C 22 alkyl radicals and C 6 to C 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.
Claim 6
Dependent Claim
23 words
The method of claim 3 further comprising the steps of adding an uncured epoxy resin and a curing amount of an aromatic diamine.
Claim 7
Dependent Claim
25 words
The gelled hydrocarbon composition of claim 1 wherein the polyfunctional aromatic amine is selected from the group consisting of phenylene diamine, methylene dianiline, and oxydianiline.
Claim 8
Dependent Claim
23 words
The method of claim 3 wherein the polyfunctional aromatic amine is selected from the group consisting of phenylene diamine, methylene dianiline and oxydianiline.
