Product name: Tributyl phosphate
Other name: Tributyl phosphate, Tri-n-butyl phosphate, Butyl phosphate, Pho sphoric acid tri-n-butyl ester
Trade name: tributyl phosphate, defoaming agent tributyl phosphate, TBP
Molecular formula: C12H27O4P
Molecular weight: 266.32
Colorless to light yellow transparent liquid with characteristic odor of the product. Melting point is less than -80ºC, boiling point is 289ºC, decomposes at boiling point temperature, relative density 0.9729 (25/4ºC), relative vapor density 9.2, dynamic viscosity 3.5-4.0mN/m, refractive index 1.4226, octanol/water distribution Log value of coefficient: 4.0, solubility in water is 0.1% (25ºC), solubility in water is 7% (25ºC), soluble in most organic solvents and hydrocarbons, insoluble or slightly soluble in glycerin, hexylene glycol and Amines.
It has the properties of ester and hydrolyzes under alkaline conditions. Dry hydrogen chloride is introduced at room temperature to generate chlorobutane. In the presence of boron trif luoride, it reacts with benzene to produce sec -butylbenzene and 1,4-di-sec- butylbenzene. Treat with an iline and dilute sodium hydro xide solution to generate dibutylan iline.
Here are some of the main applications of tributyl phosphate:
1. As a polymerization inhibitor: Tributyl phosphate can be used as a polymerization inhibitor for polymer materials to prevent oxidative polymerization of polymer materials during storage and transportation.
2. As a lubricant: Tributyl phosphate has good lubricating properties and can be used to prepare lubricants to reduce friction and wear.
3. As a surfactant: Tributyl phosphate can be used as a surfactant to improve the stability of liquid systems, such as emulsification, dispersion and dissolution.
4. As a solvent: Tributyl phosphate can be used as a solvent to dissolve and dilute other compounds, such as paints, inks and coatings.
5. Preparation of phosphate ester compounds: Tributyl phosphate can be used as raw material to prepare other phosphate ester compounds, such as trimethyl phosphate, triethyl phosphate, etc.
6. As a flame retardant: Tributyl phosphate can be used as a flame retardant to improve the flame retardant properties of the material.
7. Medical applications: Tributyl phosphate can be used to prepare drugs, such as tributyl phosphate antiviral drugs.
8. Pesticide application: Tributyl phosphate can be used to prepare pesticides, such as tributyl phosphate insecticides, fungicides, etc.
9. Analytical chemistry applications: Tributyl phosphate can be used as a reagent for experiments in the field of analytical chemistry.
In short, tributyl phosphate has a variety of applications and is widely used in chemical industry, petroleum, medicine, pesticides, coatings and other fields.
