Versuchsvorschrift

100 g (0.38 mol) of 1-fluoro-4,4-bis(trifluoromethyl)-2,3,5-trioxolanyl methyl ether (purity: 98%) was charged in a 500-ml five-necked flask. While performing nitrogen bubbling, brine at −20° C. was passed through a Dimroth condenser. While stirring at a reaction temperature of −20° C., 23.4 g (0.38 mol) of dimethyl sulfide was added dropwise using a dropping funnel over 30 minutes. The gas obtained by the reaction was collected by a water trap cooled with ice water to 0° C., and the obtained aqueous layer was analyzed by 19F-NMR. As a result, it was confirmed that 73.8 g (yield: 89%) of hexafluoroacetone trihydrate was obtained.
