摘要： This invention relates generally to a improvement in a process for the purification of fluoroxy compounds, such as bis(fluoroxy)difluoromethane and fluoroxytrifluoromethane produced by the fluorination of carbon oxides. The improvement in effecting purification of the fluoroxy compounds is effected by initially selectively removing the fluorine by contacting with a crystalline zeolite and then removing the carbon oxide by selective adsorption.

摘要： Active fluoride catalysts that are useful in producing electrophilic fluorination agents; especially useful in producing BDM from the reaction of fluorine with carbon dioxide and FTM from the reaction of fluorine with carbonyl fluoride. The fluoride catalyst comprises a mixture of two or more fluorides selected from a transition metal fluoride, an alkali metal fluoride and/or an alkaline earth metal fluoride. Alternately, the fluoride catalyst is one or more fluorides, such as alkali metal fluorides, alkaline earth metal fluorides, and/or transition metal fluorides, deposited on an inert support.

摘要： A method for the production of nitrogen trifluoride from a fluorine reactant and an ammonium ion source that is dispersed within a liquid phase reaction mixture containing one or more perfluorocarbon fluids is disclosed herein. In one embodiment, the fluorine reactant is introduced to the reaction mixture at a temperature that ranges from 90° C. to 120° C. In this embodiment, the percentage yield of nitrogen trifluoride may be about 80% or greater.
