NATIONAL ADVISORY COMMITTEE FOR AERONAUTICSnRESEARCH MEMORANDUM EXPLOSION AND COMBUSTION PROPERTIES OF ALKYLSILANESⅠ- TEMPERATURE-COMPOSITION LIMITS OF EXPLOSION FORnMETHYL, DIMETHYL, TRIMETHYL, TETRAMETHYL, AND VINYLSILANE AT ATMOSPHERIC PRESSURE
The explosion limits of five alkylsilanes were determined as a function of temperature and composition at a pressure of 1 atmosphere. Over a fuel concentration range of 2 to 10 percent, the lowest temperatures (°C) below which explosion did not occur for the five fuels studied were: tetramethylsilane (CH3)4Si, 450°; trimethylsilane (CH3)3SiH, 310°; trimethylsilane (CH3)2SiH2, 220°; methylsilane CH3SiH3, 130°; and vinylsilane H2C=CH-SiH3, 90°. Explosion limits for hydrocarbons analogous to these silliness fall in a temperature range of 500° to 600° C. Since the explosion temperatures of the alkylsilanes are lower than those of the hydrocarbons and since they decrease as hydrogen atoms are substituted for methyl groups, it was concluded that the Si-H bond is more readily susceptible to oxidation than the C-H bond.
