  Etherification of Alcohols in the Absence of Solvent: Catalytic Function of Polyethers in a Solid/Liquid Medium

  摘要：

  The catalytic action of etherified polyethylene glycols associated with a precise degree of hydration of the reacting medium allows the successful transformation of primary or secondary alcohols into corresponding ethers using very simple operating conditions.

  In order to reduce CO2 accumulation in the atmosphere, chemical fixation methodologies were developed and proved to be promising. In general, CO2 was turned into cyclic carbonates by cycloaddition with epoxides. However, the cyclic carbonates need to be converted into open-chained carbonates by transesterification for industrial usage, which results in wasted energy and materials. Herein, we report a process catalyzed by tetramethylguanidine (TMG) to afford linear carbonates directly. This process is greener and shows potential for industrial applications.

  为了减少大气中二氧化碳的积累，人们开发了化学固定方法，并证明这种方法很有前途。一般来说，二氧化碳通过与环氧化物的环化反应转化为环状碳酸盐。然而，环状碳酸盐需要通过酯交换反应转化为开链碳酸盐才能用于工业用途，这就造成了能源和材料的浪费。在此，我们报告了一种在四甲基胍（TMG）催化下直接生成线性碳酸盐的工艺。该工艺更加环保，具有工业应用潜力。

  A catalytic process is taught for non-oxidative alkylation of organic compounds, comprising alcohols, alkanes, glycols, ethers, aldehydes, ketones, carboxylic acids, esters, amines, thiols or phosphines, by alkyl groups produced from alcohols or glycols, forming products comprising ethers and other higher molecular weight alkylated compounds. The process is conducted at a reflux temperature below 200° C. in the presence of an acid, alkali or neutral salt dehydrating agent comprising sulfuric acid, phosphoric acid or their salts, lime or anhydrous calcium sulfate in the absence of zero valent metals and air. Specifically, this catalytic process converts ethanol to ethyl butyl ethers, ethyl hexyl ethers and dibutyl ethers or oxygenated gasoline as well as amines comprising n-butyl amine plus butanol to dibutyl amine and butyl hexyl amines at ambient pressure. This same catalytic alkylation chemistry, which does not constitute a condensation reaction, alkylates 4-hydroxybenzoic acid using ethanol to 4-ethoxyethylbenzoic acid products.
