Tributyl Phosphate (TBP), with the chemical formula C12H27O4P and CAS number 126-73-8, is an organophosphorus compound that possesses a unique set of chemical and physical properties, making it indispensable in various industrial applications. NINGBO INNO PHARMCHEM CO.,LTD. offers TBP of high purity, catering to the stringent demands of modern manufacturing.

Chemically, TBP is the tri-ester of phosphoric acid and n-butanol. It is characterized as a colorless, transparent, oily liquid with a high boiling point (around 289°C) and a relatively low melting point (below -80°C). Its miscibility with most organic solvents, coupled with its low solubility in water (approximately 0.1% at 25°C), contributes significantly to its utility as an extractant and a specialized solvent. While stable under normal conditions, TBP can hydrolyze under alkaline conditions over time.

One of TBP's most prominent uses is as a solvent. Its strong polarity and solvency power make it ideal for dissolving materials that are difficult to process, such as certain resins, lacquers, and printing inks. This property is leveraged in the coatings and adhesives industries to achieve better dispersion and film formation.

As a plasticizer, TBP is incorporated into polymers like PVC, cellulose acetate, and nitrocellulose. It enhances flexibility, improves processability, and can contribute to flame retardancy. This application is vital in producing flexible plastic products, films, and coatings with improved durability.

TBP also serves as an effective defoamer, crucial for controlling foam in aqueous systems, paints, inks, and papermaking processes. Additionally, its antistatic properties are utilized in the textile industry to prevent static buildup in fabrics.

Furthermore, TBP is a key component in metal extraction processes, particularly for rare earth elements and in nuclear fuel reprocessing, where its selective complexation with metal ions is exploited for purification. NINGBO INNO PHARMCHEM CO.,LTD. ensures that the TBP supplied meets the high standards required for these sophisticated applications, providing manufacturers with a reliable source for this versatile chemical.
