Abundant plant biomass has the potential to become a sustainable source of fuels and chemicals. Realizing this potential requires the economical conversion of recalcitrant lignocellulose into useful intermediates, such as sugars. We report a high-yielding chemical process for the hydrolysis of biomass into monosaccharides. Adding water gradually to a(More)

Lignocellulosic biomass is a plentiful and renewable resource for fuels and chemicals. Despite this potential, nearly all renewable fuels and chemicals are now produced from edible resources, such as starch, sugars, and oils; the challenges imposed by notoriously recalcitrant and heterogeneous lignocellulosic feedstocks have made their production from(More)
Nearly one hundred years ago, the fermentative production of acetone by Clostridium acetobutylicum provided a crucial alternative source of this solvent for manufacture of the explosive cordite. Today there is a resurgence of interest in solventogenic Clostridium species to produce n-butanol and ethanol for use as renewable alternative transportation fuels.(More)
Replacement of fossil fuels with new sustainable resources is becoming crucial due to depleting petroleum reserves, increasing global energy demand, and arising environmental concerns. Lignocellulosic biomass can be an alternative to fossil resources as a sustainable and environmentally friendly feedstock for producing chemicals and fuels. One of the major(More)
Olefin metathesis in aqueous solvents is sought for applications in green chemistry and with the hydrophilic substrates of chemical biology, such as proteins and polysaccharides. Most demonstrations of metathesis in water, however, utilize exotic complexes. We have examined the performance of conventional catalysts in homogeneous water/organic mixtures,(More)
Ionic liquids are an attractive class of solvents for biomass conversion processes. The same properties that make them advantageous—high polarity, water solubility and negligible vapor pressure—hinder their recovery from carbohydrates. We report on the synthesis of seven fluorous imidazolium chloride ionic liquids and on their ability to dissolve cellulose.(More)
Experimental General Cellulose (medium cotton linters, C6288) was from Sigma Chemical (St. Louis, MO). Other commercial chemicals were of reagent grade or better and were used without further purification. FluoroFlash ® fluorous silica gel was from Aldrich Chemical (Milwaukee, WI). The term " concentrated under reduced pressure " refers to the removal of(More)
Tuning the electronic and steric environment of olefin metathesis catalysts with specialized ligands can adapt them to broader applications, including metathesis in aqueous solvents. Bidentate salicylaldimine ligands are known to stabilize ruthenium alkylidene complexes, as well as allow ring-closing metathesis in protic media. Here, we report the synthesis(More)
