| 提纯方法 | Dissolve BHT in n-hexane at room temperature, then cool with rapid stirring, to -60℃. The precipitate is separated, redissolved in hexane, and the process is repeated until the mother liquor is no longer coloured. The final product is stored under N2 at 0℃[Blanchard J Am Chem Soc 82 2014 1960]. It has also been recrystallised from EtOH, MeOH, *benzene, n- hexane, methylcyclohexane or pet ether (b 60-80℃), and is dried in a vacuum. [Beilstein 6 IV 3511.] |
