Tributyl phosphate
View history Tributyl phosphate, known commonly as TBP, is an organophosphorus compound with the chemical formula (CH 3 CH 2 CH 2 CH 2 O) 3 PO. This colourless, odorless liquid finds some applications as an extractant and a plasticizer. It is an ester of phosphoric acid with n -butanol . Production [ edit]

- What is tributyl phosphate (TBP 126-73-8)?
- Tributyl phosphate (TBP,126-73-8) is a trialkyl phosphate that is the tributyl ester of phosphoric acid. TBP is a toxic organophosphorous compound widely used in many industrial applications, including significant usage in nuclear processing. TBP is a solvent and plasticizer for cellulose esters such as nitrocellulose and cellulose acetate.
- What is tributyl phosphate used for?
- Tributyl phosphate is used as a plasticizer for cellulose esters, vinyl resins, and lacquers; and in making fireretardants, biocides, defoamers, and catalysts. Tributyl phosphate is used as an antifoaming agent; plasticizer for cellulose esters, lacquers, plastic, and vinyl resins; component in hydraulic fluids for aircraft control systems.
- Is tributyl phosphate stable?
- It is stable, but it is incompatible with strong oxidizing agents. Tributyl phosphate (TBP) is an organophosphorus compound widely used as a solvent in nuclear fuel reprocessing for the extraction of uranium and plutonium from other radionuclides.
- Is tributyl phosphate toxic?
- Tributyl phosphate is a neurotoxic compound and an irritant. The toxic effects are characteristic of organic phosphates. It inhibits cholinesterase activity and causes paralysis.
- How is tributyl phosphate purified?
- The benzene is removed by evaporation and crude tributyl phosphate is purified by distillation in a vacuum. The fraction boiling at 160-162°/15 mm or 138-140°/6 mm is collected yielding 95 g of pure tributyl phosphate. The industrial application of this chemical is responsible for occupational exposure and environmental pollution.
- What is the initial threshold screening level for tributyl phosphate (TBP)?
- The initial threshold screening level (ITSL) for tributyl phosphate (TBP) is 22 μg/m3 based on an 8-hour averaging time. Tributyl phosphate is dissolved in a combustible solvent and is burned in a chemical incinerator equipped with an afterburner and scrubber. J & K SCIENTIFIC LTD.
