A METHOD OF PREPARING NITROALKYL NITRATE HAVING AT LEAST 4 CARBONS OF THE FORMULA: O2N-O-C(-R)(-R1)-C(-R2)(-R3)-NO2 WHERE R, R1, R2 AND R3 GROUPS ARE HYDROGEN OR ALKYL AND WHERE AT LEAST ONE OF SAID R AND R1 MEMBERS IS ALKYL, COMPRISING:: (1) SIMULTANEOUSLY CONTACTING AN ALKENE OF THE FORMULA: R-C(-R1)=C(-R2)-R3 HAVING AT LEAST 4 CARBONS, WHERE R, R1, R2 AND R3 ARE AS HERETOFORE DEFINED, WITH OXYGEN AND DINITROGEN TETROXIDE AT A TEMPERATURE BETWEEN ABOUT -40 AND 20*C. IN A MOLE RATIO OF SAID ALKENE TO SAID DINITROGEN TETROXIDE TO SAID OXYGEN OF BETWEEN ABOUT 1:0.5:1 AND 1:1.5:30 TO FORM NITROALKYLPEROXY NITROATE OF THE FORMULA: O2N-O-O-C(-R)(-R1)-C(-R2)(-R3)-NO2 WHERE R, R1, R2 AND R3 ARE AS HERETOFORE DEFINED, (2) CONTACTING SAID NITROALKYLPEROXY NITRATE WITH A REDUCING AGENT AT A TEMPERATURE BETWEEN ABOUT -20 AND 30*C. UTILIZING A MOLE RATIO OF SAID NITORALKYLPEROXY NITRATE TO SAID REDUCING AGENT OF BETWEEN ABOUT 1:1 AND 5:1 TO FORM SAID NITROALKYL NITRATE.
