Chemical: 2,4-Pentanedione, 1,1,1,5,5,5-hexafluoro-
1,1,1,5,5,5-Hexafluoroacetylacetone: Does not have an individual approval but may be used under an appropriate group standard
使用1,1,1,5,5,5-Hexafluoro-2,4-pentanedione acts as a chelating ligand. It is used as liquid crystal intermediate.
一般的な説明Hexafluoroacetylacetone forms metal-chelate complexes with Cu(II), Ni(II), Co(II), Nd(III), Rh(III), Fe(III) and Cr(III). Hexafluoroacetylacetone on hydration yields 1,1,1,5,5,5-hexafluoropentane-2,2,4,4-tetraol.
純化方法It forms a dihydrate which has no UV spectrum compared with max (CHCl3) 273nm ( 7,800) for the anhydrous ketone. The dihydrate decomposes at ~90o. The hydrate (10g) plus anhydous CaSO4 (Drierite, 30g) are heated and distilled, the distillate is treated with more CaSO4 and redistilled. When the distillate is treated with aqueous NaOH and heated, the dihydrate crystallises on cooling. The Cu complex has m 135o (after sublimation). [Gilman et al.
