摘要:A process for producing N-carboxyanhydrides is disclosed. The process produces N-carboxyanhydrides as a product and HCl as a by-product. The HCl by-product is purged from the reaction mixture by passing a purge gas through the reaction mixture as a carbonylation reagent is reacting with an amino acid or a salt thereof. The N-carboxyanhydrides produced by this process have a relatively lower chloride impurity content, relatively higher yields can be achieved, and the N-carboxyanhydrides can be produced on a larger scale.
