What is triethyl phosphate used for?
Use Summary: Triethyl phosphate is used as an industrial catalyst, a desensitizing agent for peroxides,-an ethylating agent, a plasticizer for resins, plastics, and gums.
Is triethyl phosphate flammable?
Triethyl phosphate appears as a colorless, corrosive liquid. Combustible. Slowly dissolves in water and sinks in water.
How do you prepare triethyl phosphate?
The invention discloses a method for preparing triethyl phosphate, which is characterized by comprising: a step of esterification, which is to react phosphorus oxychloride with ethanol according to a molar ratio of the phosphorus oxychloride to the ethanol of 1:(1-5) in a jacket type cooling and stirring container set.
Is triethyl phosphate toxic?
Organophosphates, such as TRIETHYL PHOSPHATE, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Is Phosphate an ester?
Phosphate has three pKas (2.2, 7.2 (5.8 as an ester) and 12.4) and is highly soluble in water, forming a large hydrated ionic shell. Phosphate is chemically versatile and can form mono-, di- and tri-esters with alkyl and aryl hydroxyl groups, as well as acid anhydrides.
What are the advantages and disadvantages of phosphate ester based fluids?
Phosphate esters have good thermal stability, excellent boundary lubrication properties, low volatility and fair hydrolytic stability (chemical stability in the presence of water). Unfortunately, phosphate esters can be hard on some elastomers such as Buna-N or nitrile, PVC coatings and paints.
Where are phosphate esters found?
Esters of these acids are present in every plant and animal cell. They are biochemical intermediates in the transformation of food into usable energy. The bonds between phosphate units in adenosine triphosphate (ATP) are called phosphoanhydride bonds.
What can phosphate ester fluids do to paint or plastic?
What are the results of exposing lacquers, oil-baised paint, plastic resins and vynil compounds to phosphate ester based hydraulic fluid? The materials will be damaged and/or softened or the paint will peel.
What does phosphate do in the body?
Phosphate is a charged particle (ion) that contains the mineral phosphorus. The body needs phosphorus to build and repair bones and teeth, help nerves function, and make muscles contract.
How do phosphate esters form?
Phosphate esters including polymers are produced by mixing polyols, such as glycerol, with phosphoric acid material followed by heating under reduced pressure in the presence of inorganic base to temperatures of from about 135° to 165° C.
What is the temperature of triethyl phosphate ( C2H5 )?
419 to 421 °F at 760 mm Hg ; 217° F (25 mm Hg) (NTP, 1992) National Toxicology Program, Institute of Environmental Health Sciences, National Institutes of Health (NTP). 1992. National Toxicology Program Chemical Repository Database.
How does Triethyl phosphate smell in the air?
Pleasant smelling 419 to 421 °F at 760 mm Hg ; 217° F (25 mm Hg) (NTP, 1992) National Toxicology Program, Institute of Environmental Health Sciences, National Institutes of Health (NTP). 1992. National Toxicology Program Chemical Repository Database.
What does Triethyl phosphate do to the environment?
Triethyl phosphate’s production and use as an insecticide production intermediate, a fire retardant, a plasticizer, an ethylating agent, a catalyst, a desensitizing agent for peroxides, and a laquer remover(1-3) may result in its release to the environment through various waste streams(SRC).
Which is the derivative of phosphoric acid triethyl phosphate?
Triethyl phosphate is a trialkyl phosphate that is the triethy ester derivative of phosphoric acid. It derives from an ethanol. Triethyl phosphate appears as a colorless, corrosive liquid. Combustible.
