Radiation decomposition of Co(acac)3 in alcohol-water matrices

The reduction yields of Co(acac)₃ in methanol-water (11) solutions and also the formation yields of the radiolysis products Co(acac)₃Co(acac)₂ + acac have been determined. These yields were found to depend considerably on the acidity and also on the initial complex concentration. Solvated electrons, transformed in acidic solutions into atomic hydrogen, less effective in reducing acetyloacetonate, are of basic significance in the reduction process of Co(acac)₃. Studies of the methanol-glycol Co(acac)₃ solutions showed that the type of radiolytic products formed depends on the composition of the matrix.
