Abstract

The mercury(63P1)-photosensitized decomposition of tetramethyltin (TMT) has been studied at 120 and 250 °C and at pressures from 10 to 20000 Pa. The gaseous products detected were ethane, methane, and hydrogen. The yields of these products increased linearly with increasing reaction time and light intensity. From the effects of O2, NO, and H2 on the yield of ethane, the major primary reactions of the mercury-photosensitized decomposition of TMT were concluded to be processes with an Sn-C bond cleavage. The quantum yields of these products were independent of the TMT pressure at higher pressures than 200 Pa at 120 °C. The quantum yield of ethane was also independent of the TMT pressure, while that of methane increased upon increasing the pressure at 250 °C. The cadmium (53P1)-photosensitized decomposition of TMT has been studied at 280 °C. The detected products were the same as those from the mercury-photosensitized decomposition, although the yield of hydrogen was very small. The pressure dependence of the yields of ethane and methane in the cadmium-photosensitized decomposition was very similar to those in the mercury-photosensitized decomposition of TMT at 250 °C.
