Process for the preparation of alpha-amino acids by hydrolysis of hydantoins at elevated pressure and elevated temperature

摘要

A process for the preparation of alpha-amino acids by hydrolysis of hydantoins in the presence of water and at least one metallic oxide under conditions such that all the starting materials are completely dissolved in the water as a result of high pressure and high temperature and only one further phase is present in the reactor in addition to the metallic oxide phase.
