Abstract : The orders of the slow reaction of propane with nitrogen dioxide (as the starting substances) are temperature-dependent. At 225C and 250C, the order according to C3H8, is 1.0; at 300C, and 350C, the order according to C3H8 is 0.75; and according to NO2-1.6. The effective energy of activation in the nitration reaction of propane by nitrogen dioxide, is 30,000 plus or minus 2,000 cal/mol in the range of 200-350C. The nitro-alkanes are the end products of the slow reaction at 250C; while at 350C they experience further transformations. Acetaldehyde, isopropyl alcohol, and methyl nitrite are intermediate products of the slow reaction. Acetone is formed as a result of secondary reactions, and does not experience any further transformation. (Author)
