実験手順

A 20-ml eggplant-type flask was charged with 12.8 g of the obtained 1,1,1,5,5,5-hexafluoroacetylacetone dihydrate and 26.0 g of 98% sulfuric acid. Then, the flask was stopped, and the mixture was stirred for 4 hr at room temperature with a magnetic mixer, followed by standing still for 1 hr to have two layers separated from each other. Then, 9.8 g of 1,1,1,5,5,5-hexafluoroacetylacetone were obtained from the organic layer. This product was found by the same gas chromatography as that of Example 1 to be 1,1,1,5,5,5-hexafluoroacetylacetone having a purity of 99.9%.
