关于ATRP聚合反应原料的处理? < >准备做ATRP 看文献上关于原料的处理,因为以前没做过,有很多地方不明白,请大家帮帮我。因为怕自己的翻译有问题,我把一些文献原话贴上来。</P> < >1.单体:苯乙烯(两种方法)</P> < > The styrene has been freshly distilled under vacuum to eliminate the inhibitor.(这里的减压蒸馏的温度是多少?)</P> < > Styrene (St, Aldrich, 99%) was washed with 5% aqueous NaOH solution to remove inhibitor and then with water, dried with MgSO4, and distilled twice over CaH2 under reduced pressure before use.(用氢化钙蒸馏是在苯乙烯中直接加入氢化钙然后直接蒸馏吗?这个可以减压吗?) </P> < > 甲基 丙烯酸甲酯</P> < >Methacrylates were purified by passing through basic alumina and collected over molecular sieves under nitrogen.(basic 氧化铝 什么意思?通过 分子筛 在氮气条件下收集产品是在氮气保护下把通过氧化铝的甲基丙烯酸甲酯再通过装有分子筛的柱子然后收集在瓶里吗?)</P> < >Methyl methacrylate were passed through an alumina column, dried over molecular sieves, deaerated by bubbling argon and stored under argon.(这个氧化铝柱为我没用过,是什么样的呢?在一个玻璃柱里填充氧化铝可以吗?)</P> < >2.溶剂(是做ATRP之前反应的溶剂) </P> < > 三乙胺 distilled over calcium hydride (CaH2) in vacuo before use.(和上面的问题有些重复,就是这个是在烧瓶中加入氢化钙(加入比例?)然后减压蒸馏的意思吗?)</P>查看更多0个回答 . 2人已关注
