| 20120123171 | Catalytic reduction of lignin acids and substituted aliphatic carboxylic acid compounds - Renewable resources comprising bagasse, corn stover, wood sawdust and switch grass are subject to direct catalytic conversion or bio-fermentation processes producing ethanol and organic by products leaving complex lignin compounds as waste for disposal. Chemical conversion of lignin compounds to aromatic lignin acids followed by reductive hydrogenation to cresol and substituted creosol compounds prepares these natural resources for chemical conversion to a form of gasoline and valued industrial compounds. The process disclosed herein is also applicable to organic carboxylic acid compounds such as natural oils producing valued liquid hydrocarbon fuels. | 05-17-2012 |
| 20120065363 | Catalytic conversion of sugars to polyethers - Sugars comprising the monosaccharides glucose and fructose, and the disaccharides sucrose and lactose are catalytically converted to polyethers in a sulfate fortified acid medium in the presence of transition metal compounds possessing a degree of symmetry. The conversion efficiency of this catalytic chemical process is improved by saturating the acidic reaction mixture with inorganic sulfate salts to reduce competitive reactions. Polyethers formed during the reaction are removed by filtration facilitating a continuous process. | 03-15-2012 |
| 20120041238 | Direct catalytic conversion of sugars to ethanol - Sugars comprising the monosaccharides glucose and fructose, and the disaccharides sucrose and mannose are catalytically converted to ethanol in a sulfate fortified acid medium in the presence of transition metal compounds possessing a degree of symmetry. This is not a fermentation process but is a catalytic chemical process where conversion efficiency is improved by saturating the acidic reaction mixture with inorganic sulfate salts to reduce competitive reactions. Ethanol formed during the reaction is removed by distillation facilitating a continuous process. | 02-16-2012 |
| 20100234644 | Formation of hydroxycarbonl compounds - Aldehyde and ketone reactants are converted to hydroxyaldehydes, polyhydroxyaldehydes, hydroxyketones and/or polyhydroxyketones in liquid phase by an aldol condensation process where a selected product carbon chain length is produced using specific concentrations of soluble inorganic base at sub-ambient temperature. | 09-16-2010 |
| 20100168377 | Catalytic conversion of amide compounds to methyl ether polymers and methyl ether ladder polymers - Catalytic processes have been developed for direct chemical conversion of amides to methyl ether polymers or methyl ether ladder polymers. Amides formed by reacting acetic acid with monoethanol amine (MEA) or acetic acid with butylamine were polymerized in the presence of transition metal catalysts in air to form linear polymers. Ethanol acetamide was catalytically converted to a linear polyether as characterized by FTIR spectra. The catalysts were based on molecular strings of mono-, di- or tri-valent transition metal compounds that opened the amide carbonyl double bond to produce linear polyethers.
