发明名称 Formation of oligomeric organophosphorus compositions with improved color
摘要 An aryl group containing phosphite, such as triphenyl phosphite, can be added to a reaction mixture comprising an organophosphorus compound, phosphorus pentoxide and an alkylene oxide, optionally in the presence of a reagent for the incorporation of hydroxy functionality in the final product. The aryl group containing phosphite is employed to improve the color characteristics of the resulting oligomeric organophosphorus composition.
