1788 results about "Hypochlorous acid" patented technology

Hypochlorous acid (HOCl) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO⁻. HClO and ClO⁻ are oxidizers, and the primary disinfection agents of chlorine solutions. HClO cannot be isolated from these solutions due to rapid equilibration with its precursor. Sodium hypochlorite (NaClO) and calcium hypochlorite (Ca(ClO)₂), are bleaches, deodorants, and disinfectants.

Process for producing high-purity ruthenium

A process comprises forming ruthenium tetroxide by blowing ozone-containing gas into crude ruthenium powder while hypochlorous acid is being added to the powder, allowing a hydrochloric acid solution to absorb the ruthenium tetroxide, evaporating the solution to dryness, and roasting the RuOCl3 crystals thus obtained in a hydrogen atmosphere. Thus a high-purity ruthenium material for thin film deposition, typically sputtering targey, is obtained which contains less than 1 ppm each of alkali metal elements, less than 1 ppm each of alkaline earth metal elements, less than 1 ppm each of transition metal elements, less than 10 ppb each of radioactive elements, a total of less than 500 ppm of carbon and gaseous ingredient elements, the material having a purity of ruthenium of at least 99.995% excluding the gaseous ingredient elements.

Poultry processing water recovery and re-use process

The inventions of the present disclosure are directed to processes designed to recover water used in certain aspects of the processing of poultry, treat the recovered water to remove solids, fats, oils and greases, animal proteins and pathogenic organisms and to reuse the treated water for poultry processing operations. The processes described herein reduce bacteria and microorganisms associated with the poultry and reuse water. The present disclosure can be employed with an approach that includes unexpected positive results of reacting ozone and chlorine with water being treated for reuse to generate hypochlorous acid and / or other effective biocides. Ozone reacts with fats, oils, and greases, dissolved in the reuse water, to produce specific surface-active agents and surfactants which reduce the surface tension of the water which it is dissolved. The combination of these surface-active agents and surfactants and the biocides cause an extraordinary release and destruction of bacteria from the poultry carcass as well as the reuse water.
