Latest Patents

Arno Pfeiffer holds a patent for a continuous process for the manufacture of methionine. This process involves subjecting 5-(.beta.-methylmercaptoethyl)-hydantoin to hydrolysis at elevated temperatures and pressures in an aqueous solution of alkali carbonate or alkali bicarbonate. During hydrolysis, ammonia and carbon dioxide are generated and subsequently removed. Once the hydrolysis is complete, methionine is separated using carbon dioxide, and the mother liquor is recirculated into the process after replenishing with fresh hydantoin.
