A method of etherifying glycols or other diols by employing renewable reagents is disclosed. In particular, the method involves contacting a diol with an alkylating agent in an alcoholic solvent, catalyzed with a catalyst (carbonic acid) generated in situ (from CO2). The mono- and di-ether products can serve as valued precursors to an array of renewable surfactants, dispersants, and lubricants, among others.
公开了一种利用可再生试剂对乙二醇或其他二醇进行醚化的方法。具体来说,该方法涉及将二醇与烷基化剂在醇溶剂中接触,催化剂为原位生成的碳酸酸催化剂(来自CO2)。这种方法生产的单醚和双醚产品可作为各种可再生表面活性剂、分散剂和润滑剂的宝贵前体。
