Why Tributyl phosphate TBP CAS 126-73-8 can be treat as a high quality defoaming agent?
That’s because it has low surface tension, and it is difficult soluble in water, widely use as defoaming agent in industry, Tributyl phosphate TBP effectively make the formed bubble film in a state of instability and fast defoaming.Our TNJ chemical specialized in TBP for more than 15 years since 2001. for more information, please contact sales16@tnjchem.com for details.

Tributyl phosphate TBP (CAS 126-73-8), known commonly as TBP, is an organophosphorus compound with the chemical formula (CH3CH2CH2CH2O)3PO. This colourless, odorless liquid finds some applications as an extractant, a plasticizer, solvent, rare earth metal separation with agent and organic intermediates. 

Specification of Tributyl phosphate TBP

Acid Value, mg KOH/g      ≤0.02

1)  Tributyl phosphate TBP is a solvent and plasticizer for cellulose esters such as nitrocellulose and cellulose acetate. It forms stable hydrophobic complexes with some metals; these complexes are soluble in organic solvents as well as supercritical CO2.

2)  The major uses of Tributyl phosphate TBP in industry are as a component of aircraft hydraulic fluid, brake fluid, and as a solvent for extraction and purification of rare earth metals from their ores.

3)  Tributyl phosphate TBP finds its use as a solvent in inks, synthetic resins, gums, adhesives (namely for veneer plywood) and herbicide and fungicide concentrates.

4)  As it has no odour, it finds use as anti-foaming agent in detergent solutions, and in various emulsions, paints, and adhesives.

5)  Tributyl phosphate TBP is also found as a defoamer in ethylene glycol-borax antifreeze solutions. In oil-based lubricants addition of TBP increases the oil film strength. It is used also in mercerizing liquids, where it improves their wetting properties. It is also used as a heat exchange medium.TBP is used in some consumer products such as herbicides and water thinned paints and tinting bases.

Storage & Handling

Case of high fever, open flame or contact with oxidants, cause a fire hazard, thermal decomposition produces highly toxic phosphorus oxide fumes.

Always refer to the Material Safety Data Sheet (MSDS) for detailed information on handling and disposal.
