摘要:
TETRAACETONIRILOLITHIUMHEXAFLUOROPHOSPHATE, A NEW COMPOUND PREPARED BY REACTING LITHIUM FLUORIDE AND PF5 OR PREVIOUSLY PREPARED LIPF6 WITH EXCESS CH3CN, IS DISCLOSED. TETRAACETIONITRILOLITHIUMHEXAFLUOROPHOSPHATE IS USEFUL FOR THE PRODUCTION OF HIGH PURITY EXCEPTIONALLY ACTIVE LIPF6 WHICH IS ALSO A NEW COMPOSITION OF MATTER. THE PREPARATIONS OF THESE NEW COMPOSITIONS ARE ALSO DISCLOSED.
摘要:
AN ANNHYDROUS OXO-SALT OF BORON OR BORIC OXIDE IS MIXED WITH AN ALKALI OR ALKALINE EARTH FLUOROSULFONATE AND HEATED, PREFERABLY IN THE RANGE OF ABOUT 100-200*C. TO EVOLVE BORON TRIFLUORIDE WICH IS RECOVERED AS PRODUCT.
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:
High purity, highly surface active LiAsF6 is prepared by warming a pure tetraacetonitrilolithium hexafluoroarsenate complex under temperature and pressure conditions sufficient to dissociate the complex and evolve all the CH3CN, said conditions being below that at which the LiAsF6 will dissociate.
摘要:
TETRAACETONITRILOLITHIUM HEXAFLUOROPHOSPHATE AND TETRAACETONITRILOLITHIUM HEXAFLUOROARSENATE, NEW COMPOUNDS, AND THEIR PREPARATION FROM LITHIUM FLUOIDE AND PF5 OR PREVIOUSLY PREPARED LIPF6 WITH EXCESS CH3CN, AND LIASF6 WITH EXCESS CH3CN, RESPECTIVELY, ARE DISCLOSED. TETRAACETONITRILOLITHIUM HEXAFLUOROPHOSPHATE AND TETRAACETONITRILOLITHIUM HEXAFLUOROARSENATE ARE USEFUL FOR THE PRODUCTION OF HIGH PURITY EXCEPTIONALLY ACTIVE LIPF6 AND LIASF6. THE PREPARATIONS OF THESE NEW COMPOSITIONS ARE ALSO DISCLOSED.
摘要:
A method of producing boron trifluoride or phosphorus trifluoride using a metal fluorosulfonate fluoride, MF(FSO3), as the fluorinating agent is disclosed. Boric acid, H3BO3, and phosphorous acid, H3PO3, respectively, are employed as the boron or phosphorus source.
摘要:
Phosphorus pentafluoride and fluorophosphoric acids are prepared from a fluoride salt, phosphoric acid or monofluorophosphoric acid, and sulfur trioxide by heating the mixture to evolve phosphorus pentafluoride and/or fluorophosphoric acid gases, and recovering the gases.
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.
