AbstractThe following systems were investigated at a pressure of 60 cm Hg as well as at lower pressures: CH4O2CO2, CH4O2SO2, CH4N2OCO2 CH4N2OSO2, CH4CH3ClO2, CH4O2N2O, CH3ClN2O in continuation of an investigation of the explosivity of H2O2N2 mixtures published in this journal.The phenomena which were exhibited therein were described. It was found that at low pressure the wall of the reaction vessel becomes catalytically active, if explosions take place in it repeatedly. The change of pressure resulting from an explosive reaction was investigated in some cases.
