Abstract:
The present invention provides a method for the production of a high-temperature high-pressure fluid which can be caused to reach specified conditions in a short time, a high-temperature high-pressure reaction method, and a reaction system for the same, and the present invention comprises a method for the production of a high-temperature high-pressure fluid in which the reactants can be caused to reach a prescribed temperature in 5 seconds or less by mixing two or more high-pressure fluids at different temperatures in a flow system, a high-temperature high-pressure reaction method which utilizes this production method of a high-temperature high-pressure fluid, and which reduces the temperature elevation time to the prescribed reaction temperature to 5 seconds or less by mixing a carrier fluid at a temperature higher than the prescribed reaction temperature with substrate solution(s) at a temperature of 100null C. or lower and reacting these fluids inside a reaction vessel, thus suppressing side reactions that occur during the temperature elevation and making it possible to perform short-time chemical reactions efficiently and selectively, and a reaction system for this reaction method.
Abstract:
The invention relates to (1) pressure-mediated dissociation of an analyte complexed with an endogenous binding partner to enable detection of a complex formed from the analyte and an exogenous binding factor, (2) pressure-mediated association of an analyte and an exogenous binding partner to enable more rapid and/or more sensitive detection of an analyte, and (3) pressure-mediated association and dissociation of biomolecular complexes to enable separation of one biomolecule from a complex mixture. Pressure can be used to improve assays by dissociating endogenous analyte complexes and improving assay speed and sensitivity by associating the analyte molecules with exogenously supplied binding partners. Pressure can also be used to improve the separation of compounds from contaminated mixtures. Methods of assaying an analyte in a sample having an endogenous complex between the analyte and an endogenous sample component include dissociating the analyte from the endogenous component using pressure and reacting the analyte with an exogenously supplied specific binding reagent to determine complexation between the analyte and the binding reagent.
Abstract:
A hydrothermal reaction is performed on an aqueous medium without adding an oxidizing agent, and then another hydrothermal reaction is performed in the presence of an oxidizing agent, thereby reducing a chemical oxygen demand of the aqueous medium. An apparatus for performing a hydrothermal reaction has a fluid inlet being capable of introducing an oxidizing agent in a fluid form during a hydrothermal reaction.
Abstract:
A continuous hydrothermal synthesis method which comprises pressurizing and heating a material slurry below a saturated vapor temperature or pressurizing a material slurry at normal temperature, pressurizing and heating an aqueous liquid above the saturated vapor temperature, atomizing and mixing the slurry and the aqueous liquid, effecting hydrothermal synthesis in a reaction section above the saturated vapor temperature, cooling the reaction product and taking out the product while retaining the pressurized state in the system by alternately opening and closing shut-off valves provided above and below a product discharging section or through a thin pipe provided in the product discharging section. The method is performed using an apparatus comprising heating-pressurizing sections respectively connected to a material slurry feeding section and an aqueous liquid feeding section, an atomizing-mixing section and a reaction section provided after these feeding sections, and a product discharging section.

Abstract:
A process for increasing the amount of isolatable products in a by-product stream generated in the production of 1,6 hexanediol includes combining the by-product stream with water to form a combination of the water and the by-product stream; and reacting the combination at a temperature between about 250.degree. C. to about 400.degree. C. at a pressure from about 1,000 psig to about 3,000 psig to form one or more reaction products.
