Tributyl phosphate, an organic compound with the formula C12H27O4P or (C4H9)3PO4, is a colorless, almost odorless liquid. Mainly used as a solvent, but also often as nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride plasticizer, rare metal extractant, etc., heat exchange medium. Due to its low surface tension, slightly soluble in water, it can be used as an industrial defoamer, effectively making the formed foam film in an unstable state and quickly defoaming. Cannot be used in food/cosmetics.
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.
Used as extractants for metal complexes, nitrocellulose, cellulose acetate, plasticizers for chlorinated rubber and polyvinyl chloride, solvents for Coatings, Inks and Adhesives
