Organophosphorus compounds are stabilized against decomposition during and after recovery from their synthesis reaction mixtures by the addition to the synthesis reaction mixture of at least 0.5% by weight of an acid scavenger, based on the weight of the organophosphorus compound, before allowing the organophosphorus compound to crystallize. The invention is of particular value in the stabilization of 2,2'-alkylidene-bis(dialkylphenyl)fluorophosphites, such as 2,2'-ethylidenebis(4,6-di-t-butylphenyl)fluo-rophosphite, which is rendered more suitable for use as a stabilizer for organicpolymers, e.g., polycarbonates, by the practice of the invention.
