- 中文摘要: In the radiolysis of cyclohexane in presence of 4×10¯3M diphenylmercury (Hg φ3) three isomers of hexane, methylcyclopentane (G=0.018), benzene (G=0.42) and cyclohexene (G=0,047) were detected. Addition of benzene in the mixture of cyclohexane and Hg ..2 formed two isomers of pentane, hexane and one isomer of hexane as additional products, while cyclohexene was eliminated completely. Normally, eight products were detected in presence of 10 to 50% benzene. Total radiolytic yield of products increased in presence of 15 to 25% benzene but in presence of 35 to 50% benzene G values became very low. Considerable amount of hexane is formed in a mixture of benzene and cyclohexane but neither benzene nor cyclohexane in presence of Hg..2 formed this compound. In the presence o benzene and ..2HG hexane yield is very much reduced. Protection is observed in presence of 10% as well as 35 to 50% benzene in this system. The plot of benzene concentration in moles/litre versus 1/⊿G…………… us linear and from the slope of the straight line, the values of rate constants were found to be 2.65×10¯2 litre/mole see. , 5.25×10¯3 litre mole sec., 9×10¯7 litre/mole sec. for methylcyclopentane, cyclohexane and benzene respectively. A plot of G(-c-C6H12) versus 1/[C6H6] also gave a straight line which confirms the sponge type protection in this multicomponent system.
