Abstract: The invention relates to a method for producing phosphorous-nitrogen compounds by reacting phosphorous sulfides with an amino component, which has at least one nitrogen atom with at least two hydrogen atoms or has at least two nitrogen atoms with at least one hydrogen atom. According to the invention, the desired phosphorous-nitrogen compounds are formed a temperature Tmax of >/= 200 DEG C. These compounds are preferably used as flameproofing agents in thermoplastic molding materials which, among other things and in addition to a thermoplastic polymer, can still contain a nitrogen compound, fillers, lubricants, common additives and/or common viscosity modifiers.

Abstract: A gas mixture containing nitrogen dioxide and oxygen is used in a process for the production of phosphorus-III compounds by the oxidation of white phosphorus (dissolved in a halogenated solvent). An independent claim is also included for a method for the production of phosphorous acid by: (1) preparation of phosphorus-III oxide by the process described above; and (2) hydrolysis in water at not above 20[deg]C.
