Description
General description
Phosphoric acid (H3PO4) is useful in
industry for treating the metal surfaces to obtain better adhesion of paint and
resin coatings.[6]
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.[1] 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.[2]
• As reference standard to investigate the surface species present on
silica/alumina-supported sodium phosphates by pre- and postreaction MAS31P-NMR
and FTIR spectroscopies.[4]
• As catalyst in the vapor-phase Fries rearrangement of phenylacetate at
623K over a series of surface modified and unmodified ZSM-5.[5]
Packaging
100, 12×100, 500 mL in poly bottle
2.5 L in poly bottle
Other Notes
Concentrated phosphoric acid is approx. 85% H3PO4 (aqueous).
