Abstract

La presente se refiere a un procedimiento para la preparacion de ácido 2-amino-4-(metiltio)butanoico (conocido como metionina) por hidrolisis amoniacal de una solucion acuosa que comprende 2-hidroxi-4-(metiltio)butironitrilo (conocido como HMTBN). Esta hidrolisis tiene lugar en forma continua, sin aislamiento de los productos intermedios, a una temperatura que no excede los 250°C, partiendo de una proporcion molar de NH3/HMTBN de entre 5 y 50 y de una proporcion molar de CO2/HMTBN de entre 1 y 10. De acuerdo con este procedimiento, se obtiene una mezcla de salida que comprende por lo menos metionina, dioxido de carbono y amoníaco en la forma disuelta y productos derivados de HMTBN; y dichos productos derivados de HMTBN, el dioxido de carbono y el amoníaco son reciclados a la hidrolisis amoniacal.This refers to a process for the preparation of 2-amino-4- (methylthio) butanoic acid (known as methionine) by ammoniacal hydrolysis of an aqueous solution comprising 2-hydroxy-4- (methylthio) butyronitrile (known as HMTBN ). This hydrolysis takes place continuously, without isolation of the intermediate products, at a temperature not exceeding 250 ° C, starting from a molar ratio of NH3 / HMTBN between 5 and 50 and a molar ratio of CO2 / HMTBN of between 1 and 10. According to this procedure, an outlet mixture is obtained comprising at least methionine, carbon dioxide and ammonia in the dissolved form and products derived from HMTBN; and said products derived from HMTBN, carbon dioxide and ammonia are recycled to ammonia hydrolysis.
