Abstract
A method for the manufacture of dialkyl phosphites is disclosed wherein a P—O component containing from 1 to 6 P—O—P bonds in the molecule is reacted with an alcohol and a carboxylic acid ester having from 1 to 6 carbon atoms in the alkyl group and from 5 to 20 carbon atoms in the esterifying alkyl group of the ester. The dialkyl phosphites are formed under simultaneous removal by distillation of the carboxylic acid formed.
