Diesel fuel compositions containing certain azides for improved cetane number
Diesel fuel compositions which contain minor amounts of azides having the formula: X=N+=N- where X is selected from the group consisting of (i) (ii) (iii) where R and R' can be the same or different and are selected from the group consisting of hydrogen; alkyl straight- and branched chain hydro...

| description | Diesel fuel compositions which contain minor amounts of azides having the formula: X=N+=N- where X is selected from the group consisting of (i) (ii) (iii) where R and R' can be the same or different and are selected from the group consisting of hydrogen; alkyl straight- and branched chain hydrocarbons having from 1 to 8 carbon atoms; alkoxy groups having from 1 to 8 carbon atoms; aryl; aryloxy; nitro; hydroxy; halo; amino (except ortho to the azido); alkylamino; acyl groups having from 2 to 8 carbon atoms; alkylamido; and carbalkoxy. The minor amount of the azides in part improved cetane numbers (low ignition delay) to the diesel fuel. |
