专利号:WO-2017030685-A1 优先权日:2015-08-14 标题 :One-pot synthesis of anhydropentitol mono- and diethers 发明人:STENSRUD KENNETH 权利人:ARCHER DANIELS MIDLAND CO 摘要:A process for preparing anhydropentitol mono- and diethers from C 5 sugar alcohols is described. The process involves performing in a single reaction vessel consolidated reactions that a) cyclize dehydratively a linear C 5 sugar alcohol and b) etherify a resulting anhydropentitol. Each of the reactions is catalyzed by a very low amount of a water-tolerant Lewis acid catalyst relative to the starting sugar-alcohol. Depending on the reaction conditions, the synthesis method is efficient, selective and affords good yields of mono- and diethers. The anhydropentiol ethers can serve as renewable substitute precursors of petroleum incumbents for use in the making of surfactants and plasticizers.
