Experiments were performed in a reactor with continuous feed of n-pentane or n-hexane from a metal cylinder under argon pressure. Samples of the pyrolysis products were taken for chromatographic analysis, the main products being hydrogen, methane, ethane, ethylene, propylene, and 1-butene. Data on the yields of principal pyrolysis products are presented with yields from pyrolysis in argon at 660/sup 0/C. The maximum possible number of hydrogen atoms formed per 100 moles of n-pentane decomposed in pyrolysis in hydrogen was estimated. Replacement of argon by hydrogen lead to an increase in the overall rate constant for n-pentane decomposition by a factor of approximately 1.3; for n-hexane, 2.5.
