43-4578A METHOD OF PREPARING ULTRAPHOSPHORIC ACID ABSTRACT Ultraphosphoric acid containing a phosphorus to hydrogen ratio of greater than 1 can be prepared by bringing together in a reaction zone elemental phos- phorus and a sufficient amount of oxygen in a free- oxygen containing gas to form phosphorus pentoxide, and a sufficient amount of water to form ultraphos- phoric acid. The mole ratio of water to phosphorus pentoxide is maintained less than 1:1. Heat is removed from the product stream of the reaction zone to condense at least some of the ultraphosphoric acid which is then collected. In the preferred embodi- ment, a heat exchange fluid such as pressurized water is circulated through a cooling coil positioned to remove heat from the product stream of the reaction zone. The ultraphosphoric acid can be combined with water to provide polyphosphoric acid.
