Mixtures of sodium dihydrogenphosphate and urea were heated in a stream of nitrogen gas to prepare inorganic phosphates with phosphorus-nitrogen bonds. Although they were not produced, addition of a large amount of urea was effective for the formation of sodium cyclo-triphosphate. Lithium carbonate-ammonium dihydrogenphosphate-urea mixtures were also heated in order to prepare lithium cyclo-hexaphosphate. The cyclo-hexaphosphate was hardly obtained, while lithium cyclo-tetraphosphate produced.
