标题[实验] 关於"氢氧化钠"
时间Sun Jul 6 00:45:22 2008
1-Bromohexane (20.0 g, 120.0 mmol), phenothiazine
(20 g, 100.0 mmol), sodium hydroxide (25.0 g,
625 mmol), and DMSO (100 mL) were placed in
a 250-mL, two-necked, round-bottom flask, and
the mixture was stirred for 2 days at room temperature.
The mixture was extracted with ethyl
acetate/brine and then dried with anhydrous
MgSO4. The resulting liquid was purified by column
chromatography. The product yield was
68.5% (19.5 g).
请问先知们，上述反应中，氢氧化钠在DMSO中的溶解度很差
那该怎麽改善，这样会影响反应结果吗？
请问有人做过这个反应吗？
