Radiolysis of Ethane + Sulfur Hexafluoride and Ethylene + Sulfur Hexafluoride Gaseous Systems. Formation of SF5• Radical and its Reactivity

Abstract

Neutralization processes of ions in radiolysis of ethane or ethylene + sulfur hexafluoride systems lead to the formation of the SF5• radical. Compounds of the general formula RSF5 are formed as a result of recombination reactions with hydrocarbon radicals. In the mixture ethane +0.3% sulphur hexafluoride the radiochemical yield of SF5• is [Formula: see text] The presence of ammonia decreases [Formula: see text] to ca. 0.2, suggesting that the neutralization process of NH4+(NH3)n with SF6− ions follows some unknown path. In the present work some reactions of the SF5• radical are studied. Preliminary results indicate that the presence of SF6 influences very little, if at all, the yield of atomic hydrogen.
