Description

  • General description: Phosphoric acid (H3PO4) is useful in industry for treating the metal surfaces to obtain better adhesion of paint and resin coatings.[1]
  • Application: Phosphoric acid may be employed as standard for the determination of phosphorus-31 nuclear magnetic resonance (31P NMR) chemical shifts of the common phospholipids.[2] It may be employed in the following studies:As external standard for the analysis of lipid composition of human white matter by 31P NMR spectroscopy.[3]As external standard during the acid-labile phosphorylation of histone H4 by 31P NMR spectroscopy.[4]As reference standard to investigate the surface species present on silica/alumina-supported sodium phosphates by pre- and postreaction MAS31P-NMR and FTIR spectroscopies.[5]As catalyst in the vapor-phase Fries rearrangement of phenylacetate at 623K over a series of surface modified and unmodified ZSM-5.[6]
  • Other Notes: Concentrated phosphoric acid is approx. 85% H3PO4 (aqueous).
