DEFINITION

Classification: 558/104

(under subclass 89) Processes in which phos- phorus in a phosphorus containing reactant is bonded directly to an -XH group, wherein X is chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) and wherein H of the -XH group may be replaced by substituted or unsubstituted ammonium, or by a Group IA or Group IIA light metal.
