Abstract: The explosion limits of MVA-N_2, MVA-NO and MVA-O_2 mixtures were determined by the admission method under the conditions of the temperatures below 700℃ and the pressure below 600mmHg. The curves of explosion limits in the MVA-N_2 and the MVA-NO systems were all above that of MVA-air. N_2 was found to be diluent and NO to behave as a retarder. The particular shape (∽) of explosion limit similar to that of MVA-air was found in the isobars and isotherms of MVA-O_2 and the sharp peak was around 5% of MVA in volume. The explosion reactions of MVA-N_2, MVA-NO and MVA-O_2 can be satisfactorily explained on the basis of the thermal explosion theory, and, assumed that the order of reaction is 2, the apparent activation energies are estimated to be 30.2-30.9Kcal/mole (MVA-N_2), 27.2-27.3Kcal/mole (MVA-NO) and 27.5-30.0Kcal/mole (MVA-O_2) below 600℃.
