See full text

The invention concerns a continuous process for manufacturing methionine by alkaline hydrolysis of methionine hydantoin in aqueous phase, removing NH3 and CO2 of the hydrolysis medium, and neutralizing the obtained methioninate salt, according to which, after removal of NH3 and CO2, the hydrolysis reaction medium is concentrated to precipitate Na2CO3, said Na2CO3 being separated then recycled for alkaline hydrolysis, the latter being carried out in the presence of NaOH and Na2CO3.
