Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
A combustible energy-producing fuel mixture consisting essentially of (a) at least one fatty acid ester having the formula ##STR2## wherein R is alkyl having from 1 to 12 carbon atoms; alkoxyalkyl where the alkoxy portion has from 1-4 carbon atoms and the alkyl portion is ethyl or propyl; cyclopentyl or cyclohexyl, or hydroxy ethyl or hydroxy propyl; n=11-22; a=2n+1, 2n-1, 2n-3, 2n-5 or 2n-7 and x is 0 or 1, and (b) a middle distillate fuel, wherein the ester and middle distillates have a ratio in the range of from about 10 to 75 to about 90 to 25 percent by weight based on the total weight of the mixture.
Claim 2
Dependent Claim
110 words
A combustible energy-producing fuel mixture consisting essentially of (a) at least one fatty acid ester having the formula ##STR2## wherein R is alkyl having from 1 to 12 carbon atoms; alkoxyalkyl where the alkoxy portion has from 1-4 carbon atoms and the alkyl portion is ethyl or propyl; cyclopentyl or cyclohexyl, or hydroxy ethyl or hydroxy propyl; n=11-22; a=2n+1, 2n-1, 2n-3, 2n-5 or 2n-7 and x is 0 or 1, and (b) a middle distillate fuel, wherein the ester and middle distillates have a ratio in the range of from about 10 to 75 to about 90 to 25 percent by weight based on the total weight of the mixture.

Claim 6
Dependent Claim
26 words
The fuel mixture of claim 1 wherein the middle distillates have a boiling point in the range of from about 140° C. to about 330° C.
Claim 7
Dependent Claim
24 words
The fuel mixture of claim 1 wherein the middle distillates have a molecular weight in the range of from about 140 to about 300.
