Description

CAS: 7664-38-2 | H3O4P | 97,994 g/mol

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Användningsområde
1,2-propandiol används i frostskyddsmedel och avisningslösningar för bilar, båtar och flygplan. Det används också för att skapa ofarlig, konstgjord rök för tränings- och teaterändamål. Det används som ett fuktighetsbevarande lösningsmedel och konserveringsmedel i livsmedel. Det fungerar som lösningsmedel för färger och plaster. Vidare används det vid tillverkning av mjölksyra genom grön katalytisk oxidation, propanal och propylenkarbonat. Det används också inom veterinärmedicin som oral behandling för hyperketonemi hos idisslare. Utöver detta reagerar den med propylenoxid för att framställa oligomerer.

Löslighet
Blandbar med vatten, bensen, aceton, kloroform och eter. Oblandbar med fasta oljor.

Anmärkningar
Hygroskopisk. Inkompatibel med syraklorider, syraanhydrider, oxidationsmedel, klorformater och reduktionsmedel.
