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.

标 题 :One-pot synthesis of anhydropentitol esters from pentitols, catalyzed by water-tolerant lewis acids
发明人：STENSRUD KENNETH
权利人:ARCHER DANIELS MIDLAND CO
摘要:A procedure for preparing anhydropentitol mono, di, and tri esters is described. The process is performed in a single vessel and involves sequential dehydrative cyclization and carboxylic acid acylation steps. Each step is catalyzed by low loadings of a water-tolerant Lewis acid catalyst. The method of synthesis is efficacious and depending on the reaction condition, generates modest to high yields of the target mono-, di-, and triesters. The esters can be practical surrogates of incumbent petroleum materials of similar structure used for surfactants and plasticizers.
