PROCESS FOR THE PRODUCTION OF METHIONINE

摘要

A process for the production of methionine which comprises: (a) a hydrolysing the methionine amide or the hydroxy analogue of methionine amide in the presence of a catalyst comprising titanium to produce ammonium methioninate, said catalyst having a porosity of from 5 to 1000nm, a total pore volume of from 0.2 to 0.55 cm<3>/g and and a surface area of from 30 to 150 m<2>/g, and (b) a second step of recuperating methionine from the ammonium methioninate salt by removing ammonia. Also claimed is an industrial process for the production of methionine incorporating the aforementioned hydrolysis.
