Kinetics of formation of carbonyl compounds and alcohols under radiation-induced oxidation of n-heptane and n-nonane. Effect of temperature and dose rate

Abstract

IT WAs pointed out in papers published in 1955 [1, 2] that peroxides, carbonyl compounds, alcohols and acids are simultaneously formed during radiationinduced oxidation of hydrocarbons. I t was established [3] that carbonyl compounds are formed independently and are not conversion products ofhydroperoxides. In accordance with the data of a former paper [4] during radiation-oxidation of n-heptane and n-nonane the yield of carbonyl compounds does not change on variation in temperature from --80 to +80% whereas the alcohol yield increases. On further increasing temperature, yields of both products increase. Somewhat later during the radiation-oxidation of iso-oetane [5] it was found that two temperature ranges exist for the formation of carbonyl compounds in the -80 to + 80 ° range. In the low-temperature range of -80-0 ° yields slightly increase with higher temperature both for carbonyl compounds and for alcohols. A detailed s tudy is made in this paper of the effect of temperature and dose rate on the fomation of carbonyl compounds and alcohols by radiation-induced oxidation of n-heptane and n-nonane.
