Azoxy-methane was decompd by hot coned aq alkali with the formation of volatile base and was converted by hot HC1 into formic acid and methyl hydrazine. The IJV and JR spectra were also reported... 

Dodd , as well as Ausloos and Steacie applied relation (35) to the experimental results of acetaldehyde photolysis. The data obtained at high temperatures seem to fit the Arrhenius straight line derived from the azomethane-acetaldehyde and di-/-butyl peroxide-acetaldehyde systems. At low temperatures, however, considerable deviation from this line could be observed, the possible result of additional methane producing reactions of some sort. According to Dodd, these processes could be (i) primary process II, (//) disproportionation reaction (26) and (in) the wall reaction of the methyl radicals.

In short reaction times at 480-900 °C, the major product of the interaction is CH3NO (CH2=N-0H). With long reaction times, NH3, H O, HCN, CO, N, CO and CH3CN were also detected. Nitroso methane or its reaction products have not been found in the flash photolysis of azomethane-NO-neopentane mixtures [11]. However, the analysis procedure in this case required repeated condensation and evaporation of the products and excess reactants. Dimerisation and isomerisation to the non-volatile products (CHjNO) and (CH2=N-0H)2 probably resulted under these conditions, and nitroso methane (formaldoxime) and possible other products would not be detected by infrared (IR) measurements on the volatilised fraction of the condensate. 

The IR technique has been used to determine directly the concentration of nitroso methane formed in the photolysis of azomethane in NO [9]. The following simple mechanism adequately describes the results obtained ...
