Organic Compounds -- Part Of The Class 532-570 Series > Azo Compounds Containing Formaldehyde Reaction Product As The Coupling Component > Carbohydrates Or Derivatives > Processes ProcessesProcesses patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.12/14/06 - 20060281913 - Process for the production of crystalline xylose from sugar cane bagasse, crystalline xylose obtained by said process, process for the production of xylitol from the said xylose and crystalline xylitol obtained thereby The invention relates to a process for the production of crystalline xylose, from sugar cane bagasse, which xylose consists of microcrystals having a well-defined morphology and a narrow granulometric range, a further object of the invention being the protection of the product, crystalline xylose, manufactured according to the technological route ... 05/18/06 - 20060106210 - Extraction of ingredients from biological material The present invention relates to an improved method for isolating ingredients from biological material, in particular from sugar beet (Beta vulgaris). ... 05/11/06 - 20060100423 - Process for the preparation and separation of arabinose and xylose from a mixture of saccharides A process for the preparation and separation of the pentoses, xylose and arabinose from mixtures of saccharides by forming acetals is described. D-xylose is a precursor to xylitol, a sweetener, and L-arabinose is a precursor to the drug intermediate (R)-3,4-dihydroxybutyric acid, carnitine and agrichemicals. ... 04/20/06 - 20060084800 - Synthesis of aldonolactones, aldarolactones, and aldarodilactones using azeotropic distillation Processes for making lactones and dilactones from aldaric acids, aldonic acids, and their corresponding salts by dehydrative cyclization and azeotropic distillation. The processes can be carried out in the presence of water because water is removed by azeotropic distillation. ... 02/09/06 - 20060030700 - D-ribose, its monohydrate and their caramels This invention discloses the formation of a new molecule when one mole only of D-ribose crystalline powder is mixed with one mole only of water at room temperature which new substance is entirely different from the precursor molecule, and a monohydrate of D-ribose is the likely newly discovered molecule formed ... 02/02/06 - 20060025585 - Manufacturing process for porous material A method for the manufacture of a solid porous separation material based on a polysaccharide, said method comprising the steps of: (a) providing an aqueous solution (I) of a polysaccharide, (b) solidifying the solution, preferably by transforming the solution to a gel, and (c) optionally cross-linking the polysaccharide, with the ... 01/12/06 - 20060009637 - Molecules as produced by endothermic chemical reactions with anhydrous d-ribose This invention discloses the endothermic reaction that D-ribose undergoes with one or more molecules forming new molecules involving the ribose radical, two such endothermic reactions having been identified as being 1) one mol of D-ribose reacting with one mol of water, resulting in a monohydrate and 2) one mol of ... 10/13/05 - 20050228175 - Production method of 2-deoxy-l-ribose compound wherein R1 and R2 are each independently a hydroxyl-protecting group or R1 and R2 in combination form a hydroxyl-protecting group, R3 and R4 are each independently an alkyl group, an aralkyl group, an aryl group or a silyl group or R3 and R4 in combination form an alkylene group. ... // - 2-Deoxy-L-ribose may be prepared by reacting a compound represented by formula (1) with an organometallic compound represented by formula (2) to give a compound represented by formula (3), which is then subjected to deprotection of a hydroxyl group and production of aldehyde by acid hydrolysis: - ... 09/15/05 - 20050203291 - Process for manufacturing high purity xylose A process for manufacturing xylose by extracting hemicellulose from a cellulosic material, such as by a cold caustic extraction method, concentrating the extract, such as by nanofiltration, into a hemicaustic stream containing hemicellulose with greater than about 85 wt % xylan content, and subsequently hydrolysing the xylan from the hemicaustic ... 09/08/05 - 20050197498 - Direct, enantioselective aldol coupling of aldehydes using chiral organic catalysts Nonmetallic, chiral organic catalysts are used to catalyze an enantioselective aldol coupling reaction between aldehyde substrates. The reaction may be carried out with a single enolizable aldehyde, resulting in dimerization to give a β-hydroxy aldehyde, or trimerization to give a dihydroxy tetrahydropyran. The reaction may also conducted with an enolizable ... 09/01/05 - 20050192436 - Method for the desalting of saccharide solution and an anion exchanger The present invention provides the means for suppressing the production of decomposition reactant, isomerization reactant, colored material, and so on when a saccharide solution is desalted, thereby suppressing the production of impurities and preventing coloration of an ion exchange resin and decrease in the desalting capacity of the ion exchange ... 07/21/05 - 20050159593 - Method for deproteinization of chitosan Methods for deproteinizing chitosan are provided. Proteins are dissolved in aqueous solution under intensive agitation. Precipitated agglomerated microcrystalline product Is subject to aqueous acidic or basic salt solution, from which dissolved proteins can be removed. Residual product is deproteinized chitosan. ... 07/07/05 - 20050148767 - Self-cross-linked alkyl cellulose A process for producing a self-cross-linking alkyl cellulose derivative, which includes irradiating, with radioactive rays, a mixture of a starting alkyl cellulose derivative (the number of carbon atoms of the alkyl group is 1 through 3, the alkyl group may be substituted by a hydroxyl group or a carboxyl group, ... ### FreshPatents.com Support |
