:看看这个反应机理:频那醇的合成? < >……Zn powder (4 mmol, 0.26 g) and carbonyl compound (2 mmol) were slurried in 3 cm3 saturatedaqueous NH4Cl and 5 cm3 THF. The mixture was stirred at room temperature. The temperature rose,and after 10 min the Zn powder had disappeared. The solvents were evaporated to dryness, and theproduct was extracted with diethyl ether. The etheral layer was separated and evaporated to drynessto afford the pure pinacol.</P> < >反应的举例如下:</P> < >…(C6H5)2C=O----------------------------……((C6H5)2--COH)2</P> < > 二苯甲酮 在Zn,NH4Cl,THF,可以得到 频那醇 ?</P> < >请教反应机理.谢谢</P>查看更多1个回答 . 5人已关注
从Aspen Plus V7.3.2 起plus不再有OLE功能了? 在 aspen plusV7.3.2之前可以在plus和excel及其他windows程序之间,可以方便的通过copy with format和粘贴链接、复制和paste special来建立链接传输数据。但是从aspen plus V7.3.2以后OLE功能取消了,有图为证!着实不方便啊! 查看更多10个回答 . 4人已关注
