hexafluoroacetylacetone usage and synthesis

description hexafluoroacetylacetone acts as a chelating ligand. for example, it can forms metal-chelate complexes with ca(ii), zn (ii), cu(ii), ni(ii), co(ii), nd(iii), rh(iii), fe(iii) and cr(iii), making it be useful in extracting related metal ions. it can also be used as liquid crystal intermediate.

chemical properties clear colorless to slightly yellow liquid

purification methods 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).
