Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
65 words
A motor fuel composition comprising a major proportion of ethyl alcohol, from about 5 to 9 percent water and from about 0.0005 to 0.1 weight percent of an additive comprising at least 80 percent of a trimeric acid produced by the condensation of an unsaturated aliphatic monocarboxylic acid or a hydroxy aliphatic monocarboxylic acid having between about 16 and about 18 carbon atoms per molecule.
Claim 2
Dependent Claim
65 words
A motor fuel composition comprising a major proportion of ethyl alcohol, from about 5 to 9 percent water and from about 0.0005 to 0.1 weight percent of an additive comprising at least 80 percent of a trimeric acid produced by the condensation of an unsaturated aliphatic monocarboxylic acid or a hydroxy aliphatic monocarboxylic acid having between about 16 and about 18 carbon atoms per molecule.
Claim 3
Dependent Claim
21 words
A motor fuel composition according to claim 1 in which said trimeric acid is produced from the condensation of linoleic acid.
Claim 4
Dependent Claim
25 words
A motor fuel composition according to claim 1 containing from about 0.5 to 10 milligrams of acetic acid per 100 milliliters of said ethyl alcohol.
Claim 5
Dependent Claim
73 words
A motor fuel composition comprising a major proportion of a lower aliphatic alcohol having from 1 to 4 carbon atoms, from about 0.2 to 10 percent water and from about 0.0005 to 0.1 weight percent of an additive comprising at least 80 percent of a trimeric acid produced by the condensation of an unsaturated aliphatic monocarboxylic acid or a hydroxy aliphatic monocarboxylic acid having between about 16 and 18 carbon atoms per molecule.
Claim 6
Dependent Claim
73 words
A motor fuel composition comprising a major proportion of a lower aliphatic alcohol having from 1 to 4 carbon atoms, from about 0.2 to 10 percent water and from about 0.0005 to 0.1 weight percent of an additive comprising at least 80 percent of a trimeric acid produced by the condensation of an unsaturated aliphatic monocarboxylic acid or a hydroxy aliphatic monocarboxylic acid having between about 16 and 18 carbon atoms per molecule.
Claim 7
Dependent Claim
16 words
A motor fuel composition according to claim 4 containing from about 5 to 9 percent water.
Claim 8
Dependent Claim
21 words
A motor fuel composition according to claim 4 in which said trimeric acid is produced from the condensation of linoleic acid.
Claim 9
Dependent Claim
17 words
A motor fuel composition according to claim 4 in which said lower aliphatic alcohol is ethyl alcohol.
Claim 10
Dependent Claim
25 words
A motor fuel composition according to claim 4 containing from about 0.5 to 10 milligrams of acetic acid per 100 milliliters of said aliphatic alcohol.
Claim 11
Dependent Claim
16 words
A motor fuel composition according to claim 4 in which said lower aliphatic alcohol is methanol.
