Abstract
Trimethyl or triethyl phosphite is prepared by continuously introducing methanol or ethanol into a reaction zone containing a triaryl phosphite, said reaction zone being maintained at a temperature above the boiling point of the methanol or ethanol and the trialkyl phosphite but below that of the aryl phosphite and of the phenol produced, all boiling points being measured under the pressure conditions in the reaction zone, and continuously removing from the reaction zone a vapour stream containing the trialkyl phosphite from which the trialkyl phosphite may be recovered, e.g. by distillation in the presence of alkali metal alcoholate or phenolate. An alkaline catalyst may be present, e.g. calcium oxide, lead oxide or an alkali metal alcoholate or phenolate. The process is preferably operated under sub-atmospheric pressure. The reaction may be operated continuously, e.g. by feeding the aryl phosphite and the alkanol countercurrent into a plate column or other reaction zone.
