| 提纯方法 | Crystallise it from pet ether (b 60-80℃) or CHCl3/pet ether. Dry it in air <55℃ and store in the dark. It is soluble in CHCl3(～1:1), *C6H6(～1:1) and CCl4(~～1:2.5). It is a germicide and antibacterial as it readily liberates chlorine, and it should not smell strongly of chlorine; otherwise it should be purified. Alternatively dissolve ～15g of reagent in 75mL of hot acetic acid and precipitate it by addition of 37mL of N/10 bleaching powder solution (NaOCl), filter off, wash it with a dilute solution of the latter, dry as above (m 78-84℃) and recrystallise it.“Sharp drying” will decompose it.
