General Properties

Tri isobutyl phosphate is ester of isobutanol and phosphoric acid. It is a very strong polar solvent which is used in concrete, textile auxiliaries and paper coating compounds. It is also a good anti-foam and soaking agent. It is used to remove gases from solvents by reducing surface tension. It is also used as flame retarder in plastic production.

Production

Tri isobutyl phosphate is usually acquired by reaction of phosphor trichlorine and sodium isobutyrate.

Applications

Tri isobutyl phosphate has a wide range of uses. It is used as a solvent for inks, synthetic resins and glues. It is a commonly used anti-foam agent in vinyl latex emulsions, rubber dyes and certain textile fields. It is also used as fire retarder.

It is preferred in aviation business due to its effect on viscosity in hydraulic fluid production. It is also used in glues and textile products as it is a strong soaking agent.

Safety Measures and Toxic Values

Tri isobutyl phosphate can be irritant if it is swallowed or inhaled. It is also hazardous for skin and eyes. It may cause allergic reactions.

Like most phosphonate, it joins in phosphonate cycle in nature. It causes eutrophication in backwater thus, negatively effecting underwater life.
