CAS 7664-38-2: Phosphorsäure

Beschreibung:
Phosphorsäure, mit der CAS-Nummer 7664-38-2, ist eine farblose, geruchlose und viskose Flüssigkeit, die hochgradig in Wasser löslich ist. Es ist eine triprotische Säure, was bedeutet, dass sie drei Protonen (H⁺-Ionen) in wässrigen Lösungen abgeben kann, was zu einem pH-Wert führt, der je nach Konzentration erheblich variieren kann. Phosphorsäure wird häufig in Düngemitteln, Lebensmittelaromen und als Rostentferner verwendet, da es mit Metalloxiden reagieren kann. Es hat eine relativ niedrige Toxizität im Vergleich zu anderen Säuren, kann jedoch dennoch Haut-, Augen- und Atemwegsreizungen bei Kontakt verursachen. Die Substanz ist hygroskopisch, was bedeutet, dass sie Feuchtigkeit aus der Luft aufnehmen kann, und sie hat einen hohen Siedepunkt im Vergleich zu vielen anderen Säuren. In Bezug auf die chemische Reaktivität kann Phosphorsäure an verschiedenen Reaktionen teilnehmen, einschließlich Esterifizierung und Neutralisation, was es zu einer vielseitigen Verbindung sowohl in industriellen als auch in Laborumgebungen macht. Seine Fähigkeit, Phosphate zu bilden, ist entscheidend in biologischen Systemen, insbesondere in Energieübertragungsprozessen wie ATP.

  • Phosphoric acid, 85% aq. soln.

    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.

  • Phosphoric acid - 85% in water

    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. Phosphoric acid also has significant cytot
