    摘要: A method for the production of an aromatic phosphite by reacting an aromatic hydroxy-compound with a phosphorus trihalide in the presence of a tertiary amine and a non-protic solvent, said solvent being mobile below −20° C. Suitable tertiary amines include tri-propyl amines, tri-butyl amines, tri-n-propylamine, tri-iso-propylamine, tri-n-butylamine, tri-iso-butylamine and tri-t-butylamine.
