cranfis(欸? 同学你好眼熟XD), evanzxcv 和 jessti 大大说的都是好方法。 我之所以会寄站内信单纯只是因为我觉得回文没什麽内容，推文又太长，才寄信。 其实我就只是贴个书来看看 XD 不好意思造成大家困扰 Orz -------以下骗不到P币 因为复制贴上------- Triethylamine Dry triethylamine with CaSO4, LiAlH4, Linde type 4A molecular sieves, CaH2, KOH, or K2CO3, then distill it, either alone or from BaO, sodium, P2O5 or CaH2. 到这边就跟一般的除水没有两样。没什麽特别的。 It has also been distilled from zinc dust, under nitrogen. To remove traces of primary and secondary amines, triethylamine has been refluxed with acetic anhydride, benzoic anhydride, phthalic anhydride, then distilled, refluxed with CaH2 (ammonia-free) or KOH (or dried with activated alumina), and again distilled. 以上是需要进一步纯化，去除其他杂质。 Another purification method involved refluxing for 2 hours with p-toluenesulfonyl chloride, then distilling. Grovenstein and Williams treated triethylamine (500 mL) with benzoyl chloride (30 mL), filtered off the precipitate, and refluxed the liquid for 1 hour with a further 30 mL of benzoyl chloride. After cooling, the liquid was filtered, distilled, and allowed to stand for several hours with KOH pellets. It was then refluxed with, and distilled from, stirred molten potassium. 这部分是比较特殊的方式了，可以参考用。 有一本书叫做 Purification of Laboratory Chemicals 以上都是摘录自那本书，觉得其实蛮好用的。 Dry triethylamine 比较要注意的是它是毒物，千万要小心操作。 另外就是跟所有 solvent system 一样， quench 的时候千万要小心... --
