Phosphate esters have the general structure P(=O)(OR) 3 feature P(V). Such species are of technological importance as flame retardant agents, and plasticizers. Lacking a P−C bond, these compounds are in the technical sense not organophosphorus compounds but esters of phosphoric acid. Many derivatives are found in nature, such as ...
General chemical structure of the organophosphate functional group. In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure O=P(OR) 3, a central phosphate molecule with alkyl or aromatic substituents. [1]
Pyrophosphoric acid. In chemistry, a phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus (P) atom is in the oxidation state +5, and is bonded to four oxygen (O) atoms, one of them through a double bond, arranged as the corners of a tetrahedron.
General ester of phosphonic acid; in fact, the phosphorus has a formal charge of +1, the oxygen above it has a formal charge of −1, and the bond between them is single. In organic chemistry, phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR) 2 groups, where R is an organic group (alkyl, aryl).
Triethyl phosphate is an organic chemical compound with the formula (C 2 H 5) 3 PO 4 or OP(OEt) 3. It is a colorless liquid. It is a colorless liquid. It is the triester of ethanol and phosphoric acid and can be called "phosphoric acid, triethyl ester".
The absorbance of the blue solution can be measured with a colorimeter and the concentration of phosphate in the original solution can be calculated. Alternatively, a direct (but approximate) reading of phosphate concentration can be obtained by using a Lovibond comparator. This method for phosphate determination is known as Denigés' method ...
Phosphite esters may be used as reducing agents in more specialised cases. For example, triethylphosphite is known to reduce certain hydroperoxides to alcohols formed by autoxidation [7] (scheme). In this process the phosphite is converted to a phosphate ester. This reaction type is also utilized in the Wender Taxol total synthesis.
Husky is a line of hand tools, pneumatic tools, and tool storage products. Though founded in 1924, it is now best known as the house brand of The Home Depot, where it is exclusively sold. Its hand tools are manufactured for Home Depot by Western Forge, Apex Tool Group, and Iron Bridge Tools. [1] Its slogan is "The toughest name in tools."
