Phenylmethanethiol and phenylethanethiol are highly reactive under both thermolytic and aquathermolysis conditions. 3-Phenylpropanethiol shows some conversion, but 75% or more remains after 5 days at 250{degree}C. Initial coupling reactions of such mercaptans to form disulfides which then lose H{sub 2}S provide facile pathways for the formation of H{sub 2}S during the steam stimulation process used to recover heavy bitumens. 2-(2-Pyridyl)- and 2-(4-pyridyl)ethanesulfonic acids give a wide variety of derivatives under both thermal and aqueous conditions, with 2- and 4-methylpyridines as major products. By contrast 2-phenylethanesulfonic acid is unreactive, and its sodium salt gives only traces of styrene under aquathermolysis conditions.
