| 物理性质 | M 212.1, m 41-42℃, 42℃, 42.5-43℃, [α]54620(+) and (-) 9o, [α]D20 (+) and (-) 7.5o(c 1, n-pentane). |
| 提纯方法 | Recrystallise the ethanol from n-pentane at -40℃and sublime it at 25℃/0.3mm (use ice-cooled cold finger). It has also been purified by column chromatography through Kieselgel 60 (0.063-0.2mm mesh, Merck) and eluted with EtOAc/n-hexane (1:5), then recrystallised from n-pentane and sublimed in a vacuum. It has R F on Kieselgel 60 F 254 TLC foil and eluting with EtOAc/n-hexane (1:5). [Meese Justus Liebigs Ann Chem 2004 1986.] |
