Abstract
WHEN 1,3-dichlorotetranuoro acetone is photolysed, two CF2Cl radicals and a molecule of carbon monoxide are formed. The CF2Cl radicals combine to form 1,2-di-chlorotetrafluoro ethane, and abstract chlorine atoms from the parent ketone to form dichlorodifluoro methane1; but, in addition to these products, a significant amount of 1,3-dichlorohexafluoro propane is found in the photolysis mixture. At first it was considered that this arose from a secondary photolysis of 1,4-dichlorohexafluoro acetone formed as a result of the chlorine abstraction reaction, but quantitative investigations2 showed that it could not originate in this way.
