γ-Radiolysis of Aqueous CHCl₃ Solutions

Abstract

γ-Irradiation led to decoppositien of CHCl₃ with the G-value (G(-CHCl₃)) of 1.8 to produce CO₂ in a He-saturated aqueous solution. The yield of CO₂ was nearly equal to half amount of the consumed CHCl₃. In the N₂0-saturated systein, the G(CHCl₃) value was 2.2 and 3/4 molar amount CO₂ was preduced per 1 mole of CHCl₃, consumed The deecomposition of CHCl₃ was enhanced by the addition of HCOONa to both the He-and N₂0-saturated systems. In the presence of 500 times excess amount of HCOONa, the G(-CHCl₃) values were increased by 6.5 times in the He-saturated solution and 4.2 times in the N₂0-saturated solution. In the lower concentilation range of HCOONa the main radiolysisp roduct was CHCl₂CHCl₂. Upon increasing the concentration of HCOONa, the yield of CH₂Cl₂ increased, while that of CHCl₂CHCl₂ decreased.
