Abstract
b -Methylmercaptopropionic aldehyde is produced by reacting acrolein with an excess of methylmercaptan at -30 DEG to +50 DEG C. in the presence of a cobalt salt of an organic acid. The reaction, which may be performed at atmospheric pressure, is preferably performed employing an acrolein to methymercaptan molar ratio of less than 1 : 1.6, but above 1 : 1, and in the presence of less than 5% by weight of water or under anhydrous conditions. The cobalt salt may be used alone or on an inert carrier and, preferably, is employed as 0.1 to 0.5% by weight of the weight of acrolein. In a continuous process the first runnings from the distillation of the reaction product may be returned to the reaction vessel to act as a moderator in the reaction of the invention. The examples relate to the use of cobalt acetate, naphthenate and methylmercaptide as catalyst. Specification 687,483 is referred to.
