    Abstract: Nitroalkyl nitrate and peroxynitrates characterized by the formula:

    where R and R1 are hydrogen or alkyl of from 1 to 10 carbons, where X is R2O-, -CN, Cl, phenyl, -ONO2,

    where R2 is alkyl of from 1 to 10 carbons or phenyl and R3 is hydrogen, phenyl or alkyl of from 1 to 10 carbons, and where Y is -OONO2 or -ONO2, said nitroalkyl nitrates being prepared by first contacting a substituted alkene of the formula:

    where R, R1 and X are as heretofore defined with a mixture of dinitrogen tetroxide and oxygen to form substituted nitroalkyl peroxynitrate of the formula:

    where R, R1 and X are as heretofore defined and second contacting said peroxynitrate with a reducing agent to form said substituted nitroalkyl nitrate, the first and second contacting being conducted in the presence of inert liquid. The nitroalkyl nitrate final products of the invention are useful as fuel additives to increase power output of petroleum distillates such as gasoline and kerosene. Further, they are useful as intermediates in the preparation of surfactants, fuel and lubricant additives, insecticides, fungicides (e.g. controlling early blight in bean plants), pharmaceuticals and polymers.
