Zusammenfassung:The invention refers to an improved process for producing methionine where the by-product methionyl-methionine is quickly converted to the product methionine by a hydrolysis reaction. The invention is characterized in that the reaction is performed at high temperatures (200 DEG C to 280 DEG C) and short residence times (20 s bis 200 s). The process is suited to increase the final yield of the desired end product methionine during a process for producing methionine. Because of the higher temperatures significantly higher space-time yields can be achieved, whereby the economic efficiency of the process described by this invention can be guaranteed.
