摘要： Methods for the generation of non-equilibrium solutions of peroxyacetic acid are disclosed. These methods comprise introducing triacetin and aqueous hydrogen peroxide to water, mixing, and then adding an aqueous source of an alkali metal or earth alkali metal hydroxide. Triacetin is converted rapidly and with a high conversion rate into peracetic acid. These methods produce solutions with a high level of peracetic acid.

摘要： The present disclosure relates to a process for extracting sugars from a pretreated lignocellulosic biomass. This process consists of contacting the pretreated lignocellulosic biomass with low charges of an aqueous peroxy acid (PA) solution to produce a liquid fraction (containing a small amount of lignin and hemicellulose degradation products) and a solid fraction containing cellulose, hemicellulose and lignin. The solid fraction can then be subjected to enzymatic hydrolysis with a variety of cell wall-degrading enzymes to produce a lignin-rich residue and a sugar solution that can be fermented to a variety of (bio)chem icals.

摘要： An acetyl xylan esterase variant having perhydrolytic activity is provided for producing peroxycarboxylic acids from carboxylic acid esters and a source of peroxygen. More specifically, a Thermotoga maritima acetyl xylan esterase gene was modified using error-prone PCR and site-directed mutagenesis to create an enzyme catalyst characterized by an increase in specific activity. The variant acetyl xylan esterase may be used to produce peroxycarboxylic acids suitable for use in a variety of applications such as cleaning, disinfecting, sanitizing, bleaching, wood pulp processing, and paper pulp processing applications.

摘要： This invention provides a method for hydrophilic treatment of cellulose fibers that can prevent coloring or decrease in fiber strength. The hydrophilic treatment method comprises a first oxidation step of oxidizing cellulose fibers in a first reaction solution containing an N-oxyl compound and a re-oxidizing agent for the N-oxyl compound; and a second oxidation step of oxidizing oxycellulose fibers obtained in the first oxidation step in a second reaction solution containing an oxidizing agent for oxidizing aldehyde groups.

摘要： This invention relates to a novel non-aqueous liquid oxygen bleach composition prepared by dispersing solid peroxygen compound in the liquid in which the content of an anhydrous non-polar organic solvent and a non-ionic and anionic surfactant is controlled. The composition is formed in a high viscous paste or a gel-type suspension and can be used as a multi-purpose composition, for example, the bleach and stain remover of clothes and the cleanser of bathroom and kitchen since they have a chemical/physical stability of no loss of available oxygen, an excellent bleaching and cleaning ability due to their alkaline pH range, no change of viscosity or no phase separation during the storage and so on.
