Fluoroxy compound solutions

摘要

There is disclosed a solution of at least one fluoroxy compound, wherein said solution has a fluoroxy compound concentration of at least 0.5 meq/liter; said concentration containing about 35 to 100% of an acyl hypofluorite, based on the total number of equivalents of fluoroxy compounds present. The acyl hypofluorite has the formula X(CF2)nCOOF wherein X is H or F and n is 5 to 16. The solution is prepared by treating a suspension of a corresponding specified alkali salt with excess F2, and is useful as a selective fluorinating agent.
