Abstract

5-(beta-methylmercystoethyl)-hydantain (I) is synthesised by reacting acrolein (1.0 mol), HCN (1.0-1.5 mol), MeSH (1.0-1.5 mol) and an NH3-CO2 cpd. (1.0-4.0 mol) in a solvent (0.5-10.0 l) at 40-200 degrees, under pressure (pref. 2-5 kg/in autogenic) in a continuous process as a homogeneous, liq. system. The contact time is 5-120 min, and premixing should avoid combining MeSH with acrolein and/or HCN before the reaction vessel.
