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.

본 발명은 엔도-5-O-알킬 이소소르비드-2-O-알킬 술폰산 염 음이온 계면활성제 및 이의 위치선택적 및 효율적 제조방법에 관한 것이다. 본 발명에 따른 제조방법은 용매 또는 촉매 등의 반응 조건을 조절하여 높은 위치선택성과 우수한 수율으로 이소소르비드에 엔도형으로 알킬 사슬을 도입할 수 있으므로, 5-O-알킬이소소르비드-2-O-알킬 술폰산 염을 제조하는데 유용하게 사용될 수 있고, 상기 제조방법으로 제조된 이소소르비드에 술폰산기를 도입한 음이온 계면활성제는 낮은 표면장력 및 높은 기포력을 나타내어 계면활성제로 유용하게 사용될 수 있다.

isosorbide‐2‐O‐propyl sulfonic acid sodium salt and exo‐2‐O‐alkyl isosorbide‐5‐O‐propyl sulfonic acid sodium salt) with straight alkyl chains (hexyl, octyl, decyl, and dodecyl) were synthesized from isosorbide derivedfrom biomass, through steps of allylation, alkylation, and sulfonation. The selectivity and efficiency of the reactions were optimized by adjusting the solvent, catalyst, reactant molar ratio

A facile, straightforward method for alkylation of anhydrosugar alcohols (isohexides) using a carbonate reagent is described. The alkylation method involves: a) contacting in a solution of an isohexide with a dialkyl, diallyl, or diaryl carbonate, and the solution includes a Brnsted base; and b) producing either an alkyl ether or alkyl carbonate of the isohexide compound. The alkylation reaction is in situ, that is, performed without an extrinsic catalyst. According to the method, one can synthesize various ethers and carbonates.
