How are Alkyl/Aryl Acid Phosphates made?
The final product generally contains approximately equimolar quantities of mono-alkyl/aryl and di-alkyl/aryl acid phosphates for any given alkyl/aryl radical. However, the production process is typically not controlled such that this ratio is predetermined. Other smaller constituents may include condensed phosphates, mono-/di-alkyl/aryl orthophosphates, free alcohol, and phosphoric acid.

Where are Alkyl/Aryl Acid Phosphates used?
Phosphate Esters are among the most versatile surfactants partly thanks to their stability and solubility in alkali state. They are effective coupling agents which display outstanding wetting, emulsification, and low foaming properties. Their oxidation stability and high ignition temperatures also make them a good choice in applications where fire retardancy is required.
Key applications include:
- Plasticizers
- Hydraulic fluids
- Lubricating and anti-static agents
- Multifunctional (lubrication, corrosion inhibition and anti-wear) additives for metal cutting fluids
- Emulsifying agents
- Esterification catalysts and polymerizing agents
- Heavy duty alkaline cleaners/detergents
- Curing catalysts and accelerators in resins and coatings
- Components of rust preventive coatings for metals
- Pigment dispersion agents
- Paint driers and viscosity reducers
