text: In a process for the preparation of methionine, the steps which comprise hydrolyzing methionine nitrile by reaction with hot dilute aqueous sulfuric acid, neutralizing the reaction product to a pH of 5 to 6 by addition of ammonia, adding ammonium sulfate directly to the said neutralized product whereby a precipitate containing methionine is formed, washing the said precipitate with a substantially saturated aqueous solution of methionine, admixing the resultant washed precipitate with water whereby the methionine goes into solution and a separate layer of tarry product is formed, removing the said tarry products from the resultant aqueous mixture, and thereafter separating methionine from the remaining aqueous solution.
