    Abstract: A method of preparing a nitroketonized amide by contacting an acid amide of the formula:

    WHERE R1 is an alkenyl group of from 4 to 40 carbon atoms, where R2 and R3 alternately represent hydrogen and an alkenoyl group of from 4 to 40 carbon atoms, with dinitrogen tetroxide and oxygen, at mole ratios of acid amide to dinitrogen tetroxide to oxygen of from 1:2:2 to 1:4:60.

    Abstract: Graft copolymers are prepared in a two-stage process by first reacting, for example, 1,2-polybutadiene or an ethylene/propylene/alkylidene norbornene terpolymer, with a mixture of dinitrogen tetroxide and oxygen to form a nitrooxidized backbone polymer having incorporated therein nitro and peroxy nitrate functions which serve, in the second stage of the process, as sites for the subsequent graft polymerization of an acrylate monomer.

    Abstract: A method of preparing nitrocycloalkanones by simultaneously contacting a solution containing a cycloalkene, a denitrating agent and an organic solvent with a mixture of dinitrogen tetroxide and oxygen, the mole ratio of denitrating agent to cycloalkene being above 0.1:1 and up to about 2:1, preferably about 0.5:1 to 1:1, as a one step nitrooxidation reaction. The nitrocycloalkanones so formed are useful as fuel and lubricant additives as well as intermediates in the preparation of cyclic lactams such as caprolactam.
