Abstract
An improved process is provided for reacting starting materials in the presence of an acid catalyst in a reaction zone to produce an acid sensitive product. The starting materials are circulated in the reaction zone through a fixed bed of solid acid-type ion exchange resin to thereby catalyze the reaction, and the resulting reaction product is withdrawn from the reaction zone. Starting materials comprised a mercaptan and an aldehyde or ketone are reacted in accordance with the process to produce high yields of aliphatic hydroxyalkyl or hydroxyaryl sulfide.
