Advances in the catalysts for synthesis of ethylene glycol ethers via etherification were reviewed, and some suggestion were made for development of new catalysts.

介绍了醚化反应法合成乙二醇醚催化剂的研究进展，并对催化剂的开发提出了建议。在进行环氧乙烷与醇的醚化反应时，使用传统的碱性催化剂，反应容易形成多醚；使用传统的酸性催化剂，反应容易形成有毒物质二烷。

METHODS With thymol and bupivacaine as the internal standards for propofol and lidocaine respectively,the extraction was performed with cyclohexane.

以麝香草酚和布比卡因分别为异丙酚和利多卡因的内标，样品用环己烷提取。

To summarize this new preliminary study, we have shown that the combination of Mn and Co is an efficient catalyst for the one-step aerobic oxidation of cyclohexane to adipic acid, displaying a much higher activity than Co and Mn alone.

总结这一新的初步研究，我们已经表明，相结合的锰和钴是一种有效的催化剂一步有氧氧化环己烷合成己二酸，展示了高得多的活性比钴和Mn独立。

In aqueous solution no binding observed in crystal structure. In cyclohexane, one amylamine molecule is observed in the active site of trypsin and more sulfates are also found on enzyme surface, which are further proofs that electrostatic interaction are stronger in organic solvent.

在水溶液中，晶体结构难以观察到戊胺与牛胰酶的结合，在环己烷中，一个戊胺分子结合在胰酶的活性中心，同样酶表面观察到了更多的硫酸根，这些都进一步验证了有机溶剂中静电相互作用加强。
