DECOMPOSITION OF ALKALIAND ALKALINE EARTH PERCHLORATES
effects of gas imperfection were negligible and omitted. The constants for the Cox equation and maximum and average deviations from the experimentally observed data are given for the three compounds in Table VII. The heats of vaporization at 298.15OK. calculated for the compounds are given in Table VIII, together with the experimentally determined value of Osborne and Ginningsl!Jfor n-propylcyclopentane.

The Radiation-Induced Decomposition of the Alkali and Alkaline Earth Perchlorates. I.
Product Yields and Stoichiometry'"
by L. A. Prince and E. R. Johnson1b Chemistry Department, Stevens Institute of Technology, Hoboken, New Jersey (Received ,Varch 6, 1964)
The radiation-induced decomposition of the alkali and alkaline earth perchlorates has been studied. C103-, C102-, C102, C10-, C1-, 0 2 , and metal oxide (or superoxide), and possibly some C103, are the products. Good stoichiometry has been obtained. The order of decreasing GOc,o,- is Cs > Rb > Mg > Sr > S a > Ca > I< > Li > Ba.
Previous studies on the radiation-induced decomposition of the solid inorganic perchlorates have indicated that chlorine in almost all of its oxidat on states appears in the products of the decomposition. Heal2 identified chloride, chlorate, and oxygen, and indicated the possible presence of hypochlorite and chlorite as products in the radiolysis of solid I
