ABSTRACT:
The addition reaction of hydrogen sulfide with an olefinically unsaturated alkyl carboxylate, to form a product mixture at least 55 weight percent alkyl mercaptoalkanoate, is made immune from significant effects on product selectivity caused by CO.sub.2 contamination of the hydrogen sulfide by selection of the addition catalyst from inorganic and organic bases having an ionization constant greater than 2.0.times.10.sup.-5 at 25.degree. C., such as triethylamine.
