| 提纯方法 | Dissolve it in water and shake it repeatedly with small amounts of diethyl ether which extracts, preferentially, 1,1-dichloroacetone present as an impurity. The chloroacetone is then extracted from the aqueous phase using a large amount of diethyl ether, and distilled at slightly reduced pressure. It is dried with CaCl2 and stored at Dry-ice temperature. Alternatively, it was stood over CaSO4, distilled and stored over CaSO4. It is steam volatile. The 2,4-dinitrophenylhydrazone forms yellow needles from EtOH with m 120℃ or 124℃.
