Abstract
Photolysis of methanethiol in the presence of oxygen has been investigated at 228.8 and 254–265 nm. The major products detected were 2,3-dithiabutane and a liquid, tentatively identified as hydrogen peroxide. The quantum yield of sulfur dioxide was found to be small (3 × 10−5) at 25 °C, increasing only by an order of magnitude at 125 °C. It has therefore been concluded that the reaction between CH3S and oxygen is very slow if it occurs at all.Keywords
