CAS 7664-38-2: Acide phosphorique
Description :
Acide phosphorique, avec le numéro CAS 7664-38-2, est un liquide incolore, inodore et visqueux qui est hautement soluble dans l'eau. C'est un acide triprotique, ce qui signifie qu'il peut donner trois protons (ions H⁺) dans des solutions aqueuses, ce qui entraîne un pH qui peut varier considérablement en fonction de la concentration. Acide phosphorique est couramment utilisé dans les engrais, les arômes alimentaires et comme décapant de rouille en raison de sa capacité à réagir avec les oxydes métalliques. Il a une toxicité relativement faible par rapport à d'autres acides, mais peut néanmoins provoquer des irritations de la peau, des yeux et des voies respiratoires au contact. La substance est hygroscopique, ce qui signifie qu'elle peut absorber l'humidité de l'air, et elle a un point d'ébullition relativement élevé par rapport à de nombreux autres acides. En termes de réactivité chimique, Acide phosphorique peut participer à diverses réactions, y compris l'esterification et la neutralisation, ce qui en fait un composé polyvalent tant dans les environnements industriels que de laboratoire. Sa capacité à former des phosphates est cruciale dans les systèmes biologiques, en particulier dans les processus de transfert d'énergie comme l'ATP.

CAS :Phosphoric acid is used mainly in fertilizers. It is used as an external standard for phosphorus-31 Nuclear magnetic resonance (NMR); as an electrolyte in phosphoric acid fuel cells and as a catalyst in the hydration of alkenes to produce alcohols, predominantly ethanol. It finds application as a buffer agent in biology and chemistry; as a solution for anodizing and as a cleaner by construction trades to remove mineral deposits, cementitious smears and hard water stains. It is also used as a pH adjuster in cosmetics and skin-care products and a dispersing agent in detergents and leather treatment. It plays an important role in the preparation of albumin derivatives. It is an important starting material used in the preparation of disodium hydrogen phosphate, trisodium phosphate, calcium dihydrogen phosphate and monohydrogen phosphate. It is also used in dentistry and orthodontics as an etching solution as well as a sanitizing agent in dairy, food and brewing industries. It serves as an acidic fruitlike flavoring in food products. It is widely used to remove rust in steel tools or surfaces by converting the rusted ion in to water soluble phosphate compound.

CAS :Phosphoric acid is a colorless, corrosive liquid with an acrid odor. It is soluble in water and reacts with most organic substances. Phosphoric acid is used as a catalyst, in the manufacture of fertilizers and food additives, and as the active ingredient in some cola drinks. It also has applications in the textile industry, where it is used to remove starch from cotton fibers. Phosphoric acid is an oxidizing agent that can be used to disinfect cancer tissues. This chemical has high resistance to transfer reactions, which makes it useful for analytical methods such as electrochemical impedance spectroscopy (EIS). The EIS technique can be used to measure pH levels by measuring the impedance of a solution when a small voltage is applied across its surface. Benzalkonium chloride is added as a preservative or bactericide because phosphoric acid readily reacts with many other organic materials and may cause explosions if not diluted with water.
