The gaseous mixtures of iso-propanol of 10 torr with carbon dioxide of 0∼1990 torr were irradiated with Co-60 gamma radiation up to 50 kGy, and the products such as carbon monoxide, acetone, methane, ethane, C3Ha, C4Hb and tert-butanol were analyzed by gas chromatography. G(CO) value of 4 was obtained from the gas mixtures containing more than 490 torr of carbon dioxide. The production rates of the organic products and the decomposition rate of iso-propanol increased linearly with the pressure of carbon dioxide, and G(-iso-Propanol) and G(Acetone) values increased by 4 and 2, respectively, with each 10 torr increment of carbon dioxide pressure. The mechanisms of the radiolytic decomposition of iso-propanol and the production of carbon monoxide and organic materials are discussed on the basis of the experimental results of the present study.
