摘要:A ruthenium-phosphine complex can be used as a catalyst in a method for the catalytic synthesis of urea. The method may comprise more particularly a reaction of formamide or of formamide with ammonia in the presence of the catalyst to form urea and hydrogen. Through the use of the ruthenium-phosphine complex as the catalyst, catalytic preparation of urea from formamide or from formamide with ammonia is provided for the first time. This allows for synthesis under mild conditions and virtually no formation of byproducts. Further, using an acid as a cocatalyst in the catalytic synthesis or the reaction can lead to an improvement in urea yield.

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.
