    摘要: PHOSPHORYL FLUORIDE IS REACTED WITH SULFUR TRIOXIDE TO FORM A PHOSPHORYL FLUORIDE-SULFUR TRIOXIDE ADDUCT AND THE ADDUCT CAN BE SOLVOLYZED BY HYDROGEN FLUORIDE TO FORM PHOSPHORUS PENTAFLUORIDE AND SULFURIC ACID. THE PHOSPHORYL FLUORIDE-SULFUR TRIOXIDE ADDUCT IS A NEW COMPOUND IN THE FORM OF A COLORLESS LIQUID HAVING A LOWER VAPOR PRESSURE THAN ITS INDIVIDUAL COMPONENTS BY A FACTOR OF ABOUT 10.

    摘要: Phosphorus pentafluoride and fluorophosphoric acids are prepared from a fluorine source selected from fluorosulfonate fluorides and mixtures of fluorides and fluorosulfonates and a phosphorus source selected from phosphoric acid and mono- or difluorophosphoric acid. By an analogous process, arsenic pentafluoride and fluoroarsenic acids are prepared by fluorinating an arsenic source selected from arsenic acid and monofluoroarsenic acid.

    摘要: PHOSPHORYL FLUORIDE IS REACTED WITH HYDROGEN FLUORIDE TO FORM PHOSPHORUS PENTAFLUORIDE AND HEXAFLUOROPHOSPHORIC ACID, AND THE HEXAFLUOROPHOSPHORIC ACID MAY BE REACTED WITH SULFUR TROXIDE, PYROSULFURIC ACID OR FLUOROSULFONIC ACID TO FORM ADDITIONAL PHOSPHORUS PENTAFLUORIDE. THE HEXAFLUOROPHOSPHORIC ACID FROM ANY SOURCE MAY BE REACTED WITH THE SULFUR TRIOXIDE AND/OR PYROSULFURIC ACID TO LIBERATE PHOSPHORUS PENTAFLUORIDE.

    摘要: TO REDUCE THE VISCOSITY OF CONDENSED PHOSPHORIC ACIDS SO THAT THEY CAN BE PUMPED OR OTHERWISE READILY HANDLED OR TREATED, THE F CONTENT OF THE ACIDS IS RAISED ABOVE TWO PERCENT AND PREFERABLY ABOVE FOUR PERCENT. THE FLUORINE MAY BE ADDED IN THE FORM OF A FLUORINE-CONTAINING COMPOUND, SUCH AS FLUOROPHOSPHORIC ACID, DIFFLUOROPHOSPHORIC ACID, HEXAFLUOROPHOSPHORIC ACID, HYDROGEN FLUORIDE, ETC. THE FLUORINE TREATMENT INHIBITS CRYSTALLIZATION OF THE ACID AND, IN THE CASE OF WET PROCESS PHOSPHORIC ACID CONTAINING SOLIDS, DISSOLVES SOLIDS IN THE ACIDS.
