提纯方法 | It forms a dihydrate which has no UV spectrum compared with ? max (CHCl3) 273nm (7,800) for the anhydrous ketone. The dihydrate decomposes at ~90℃. 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 135℃(after sublimation). [Gilman et al.
