急!一段英文合成文献,很深奥,谁能解一下? < >In a <FONT style="BACKGROUND-COLOR: #ffff00">screw-top vessel</FONT> (有旋盖的反应瓶?)with a Teflon O-ring( 聚四氟乙烯 O圈?什么东西) was placed the hydroxylamine 8a (0.67 g, 1.85 mmol) and 2-methyl-2-propanol(3 mL). </P> < ><FONT style="BACKGROUND-COLOR: #f7f709">Liquid NH3(2 mL</FONT>)(这个怎么搞定啊?请指教) was <FONT style="BACKGROUND-COLOR: #ffff00">condensed using a cold finger</FONT> (???)(dry ice/acetone) into the cooled (-78 度) reaction vessel. (上面这步用液氨加料的实在不理解,请赐教)The vessel was sealed, the ice bath was removed, and the reaction mixture was allowed to stir at rt for 2 h. </P> < >The reaction mixture was then placed in the refrigerator overnight. The vessel was then recooled to -78 度 and opened. The ice bath was removed, the reaction mixture was allowed to come to rt, and the NH3 was allowed to evaporate.</P> < >有谁做过类似的,就更好了。我的邮箱<a href="mailto:qinweb@163.com" target="_blank" >qinweb@163.com</A></P>查看更多4个回答 . 1人已关注
EIS 解释电子和离子?我做的材料在 铁氰化钾 中 测试 EIS,后面审稿人给的意见是“the work can be improved by extracting transport resistance from EIS for both electron and ions to better explain the experimental observations."??我现在对这句话实在理解困难,是说我的EIS解释有问题吗? 希望大家可以热心帮忙一下,真的万分着急!!!非常感谢!!!!查看更多7个回答 . 1人已关注
