A fuel or fuel blendstock for jet, gas turbine, rocket, and diesel engines, particularly jet, rocket, and diesel engines that utilizes components of conventional petroleum not currently utilized for jet, gas turbine, rocket, and diesel fuels, such as benzene, linear, and lightly branched alkanes, that may be alkylated with aromatic moieties to make monoaromatics for use in jet and diesel fuels. Additionally, a fuel having such monoaromatics having multiple desired properties such as higher flash point, low pour point, increased density, better lubricity, aerobic degradability, reduction in toxicity, and additionally can deliver benefits in blendstocks.

What is claimed is: 1. A fuel composition for use in jets, gas turbines, rockets, or diesel engines comprising: (a) from about 5% to about 99% by weight of the fuel composition of formula wherein the A moiety is selected from benzene, cyclohexane, and mixtures thereof, such that the A moiety i
What is claimed is: 1. A fuel composition for use in jets, gas turbines, rockets, or diesel engines comprising: (a) from about 5% to about 99% by weight of the fuel composition of formula wherein the A moiety is selected from benzene, cyclohexane, and mixtures thereof, such that the A moiety is non-terminally attached to the L moiety and further such that the A moiety is directly connected to the L moiety; R′ is selected from hydrogen and C1 to C3 alkyl; R″ is selected from hydrogen and C1 to C3 alkyl; wherein both of R′ and R″ are nonterminally attached to the L moiety; the L moiety is a linear acyclic aliphatic hydrocarbyl such that the sum of carbons in the L moiety, R′, and R″ is from 5 to 25 carbons; (b) at least about 0.01% of fuel additives; and (c) from 0% to about 90% of conventional jet, gas turbine, rocket or diesel blendstocks. 2. The fuel composition according to claim 1 wherein the pour point of the fuel is about −40° C. to about −80° C., for use in a jet, rocket, or gas turbines. 3. The fuel composition according to claim 1 wherein the flash point of the fuel is about 38° C. to about 145° C. 4. The fuel composition according to claim 1 wherein the density is about 0.700 g/ML to about 0.900 g/mL. 5. The fuel composition according to claim 1 wherein the sum of carbons in the combined L moiety, R′, and R″ is from C5-14. 6. The fuel composition according to claim 1 wherein the A moiety is located on the alpha- or beta-carbon to the terminal carbon of the L moiety. 7. The fuel composition according to claim 1 which is essentially free of polycyclic aromatic substitutents and essentially free of unreacted benzene. 8. The fuel composition according to claim 1 wherein the fuel composition is a jet fuel having a minimum smoke point of at least 20 mm. 9. The fuel composition according to claim 1 wherein the fuel composition is a diesel fuel having a cetane index of at least 40. 10. The fuel composition according to claim 5 wherein R′ and R″ are hydrogen and the A moiety is benzene. 11. The fuel composition according to claim 5 wherein R′ is methyl and R″ is hydrogen or methyl, and the A moiety is benzene. 12. The fuel composition according to claim 1 wherein the pour point of the fuel is about −20° C. to about −80° C., for use in diesel engines.
