Process for the production of methionine |
摘要 |
A process for the production of methionine which comprises (a) hydrolyzing the methionine amide in the presence of a catalyst comprising titanium to produce ammonium methioninate, said catalyst having a porosity of from 5 to 1000 nm, a total pore volume of from 0.2 to 0.55 cm3/g and a surface area of from 30 to 150 m2/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.
