摘要： A process for dissolving modified cellulose includes contacting modified cellulose with a solvent in a mixture to form swelled modified cellulose and then contacting the mixture with a salt to dissolve the swelled modified cellulose. The dissolved modified cellulose is used to form at least one of a predictably degrading coating, film, or a fiber.

摘要： An economically viable method of fermenting a mixture of sugars resulting from the acid hydrolysis of material containing cellulose and hemicellulose allows for the simultaneous fermentation of both pentose and hexose sugars. The sugar solution is mixed with a microbial organism known to produce a useful fermentation product, and the fermentation process is allowed to proceed for 3-5 days, during and after which the fermentation products are removed and purified.

摘要： A economically viable method for producing sugars using concentrated acid hydrolysis of biomass containing cellulose and hemicellulose is disclosed. The cellulose and hemicellulose in the biomass is first decrystallized and then hydrolyzed to produce a hydrolysate containing both sugars and acid. Silica and silicates present in the biomass can then be removed for further processing. The remaining solids are then subjected to a second decrystallization if necessary and a second hydrolyzation to optimize the sugar yields.

摘要： Oxidized cellulose material is neutralized, by contacting an acidic oxidized cellulose material with a water and alcohol solution of a basic salt of a weak organic acid, e.g. sodium acetate, to elevate the pH of the cellulosic material to between 5 and 8. The resulting neutralized product is storage stable and has therapeutic applications, including hemostasis and adhesion prevention. Furthermore, the neutralized product may be impregnated with acid-sensitive hemostatic agents, such as thrombin, to enhance its hemostatic properties, or with acid-sensitive adhesion-preventive agents, such as t-PA, to enhace its adhesion-prevention properties.

摘要： A composition which consists essentially of a mixture of oligomeric and polymeric oxidation products of cellulose, hemicellulose and lignin containing carboxy, ether and hydroxy groups as obtained by the direct oxidation of a woody plant material, preferably in an aqueous suspension thereof, using alkali hypohalite in a one stage oxidation procedure or nitrogen dioxide, alkali periodate or lead tetraacetate followed by alkali chlorite or alkali hypochlorite in a two stage oxidation procedure. The resulting oxidation products as obtained by one of these specific processes are especially valuable as additives to a surface active detergent or cleaning agent.
