METHOD FOR THE MANUFACTURE OF DIALKYL PHOSPHITES

摘要

A method for the manufacture of dialkyl phosphites by reacting a P-O component containing from 1 to 6 P-O-P bonds in the molecule, with an alcohol and a ketal corresponding to a selected formula, said ketal will not lead to the formation of an enol structure. The level of the ketal is expressed in relation to the level of co-reactants. A preferred ketal is void of any carbon-hydrogen bonds on the a-carbon atom in the ketal structure.
