Abstract:

Sensitization of the thermal decomposition of 2 acetals, and a detailed study of the NO inhibited methylal decomposition are reported. The influence of several sensitizers on the thermal decomposition of methylal and dimethyl acetal was studied. The activity of ethylene oxide on the normal decomposition of methylal was tested at several temperatures 421, 478 and 520 C and starting pressures. If very small amounts of NO are added to the methylal-ethylene oxide mixtures, the decomposition rate of the sensitized reaction is greatly reduced, the inhibition being transitory in character. Experiments on the pressure rate and the quantitative analyses indicated that ethylene oxide may be considered as a sensitizer of the dimethyl acetal decomposition. Biacetyl seems to be efficient in sensitizing a reaction in a NO inhibited methylal decomposition at 520 C.
