Document Type and Number:
WIPO Patent Application WO/2017/179458
Kind Code:
A1
Abstract:
Disclosed is a method for purifying a first fluorinated interhalogen compound XFn. This method includes: a converting step of changing the number of fluorine atoms in the first fluorinated interhalogen compound to generate a second fluorinated interhalogen compound Fn±a; an impurity removing step of removing impurities from the second fluorinated interhalogen compound; and a reconverting step of changing the number of fluorine atoms in the second fluorinated interhalogen compound to generate the first fluorinated interhalogen compound represented by formula (1). By removing impurities from the fluorinated interhalogen compound, a high purity fluorinated interhalogen compound can be produced.
