Abstract
Activated olefinically unsaturated organic compounds such as esters, acids, ketones, nitriles, and the like, are reacted with hydrogen sulfide in the presence of at least one of magnesium oxide and anion exchange resins catalysts to produce saturated sulfur-containing compounds. In a specific embodiment, unsaturated carboxylates are converted in high yields to mercaptoalkanoates.
Claims5
A continuous process for the production of mercapto-substituted compounds which comprises passing a mixture of hydrogen sulfide and at least one olefinically unsaturated compound in which the double bond is conjugated with an activating group selected from the group consisting of carbonyl, carboxyl, carboxylate, carboxamide, nitrile, nitro and sulfoxide through a reaction zone comprising a bed of magnesium oxide catalyst which optionally contains silica or other suitable binding agent under reaction conditions which produce saturated sulfur compounds and separating excess hydrogen sulfide from the product mixture removed from said reaction zone.
