Abstract: An olefinically unsaturated alkyl carboxylate is reacted with hydrogen sulfide in the presence of a lower alkanol using an addition catalyst with water and/or sulfur cocatalyst to give an alkyl mercaptocarboxylate/dialkyl thiodicarboxylate mixture having a high proportion of the mercaptocarboxylate.

Abstract: The process of preparing thioethers by reacting aliphatic thioalcohols, e.g., mercaptans, including hydrogen sulfide with activated, alpha, beta unsaturated compounds ##STR1## capable of participating in the Michael Addition Rection* in which X is a suitable electron withdrawing group.
