The fully dissociated anion (k = n − 2x + 2) has formula [P n O 3n−x+1] (n−2x+2)−. The term phosphate is also used in organic chemistry for the functional groups that result when one or more of the hydrogens are replaced by bonds to other groups.
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]
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 ...
Triphenyl phosphate (TPhP) is the chemical compound with the formula OP(OC 6 H 5) 3. It is the simplest aromatic organophosphate. This colourless solid is the ester (triester) of phosphoric acid and phenol. It is used as a plasticizer and a fire retardant in a wide variety of settings and products. [3]
Trixylyl phosphate (TXP) is an aromatic phosphate ester. It was historically used as a flame retardant for acetate plastics (cellulose nitrate and cellulose acetate) and PVC. It also saw significant use as a fire-resistant hydraulic fluid. Trixylyl phosphate is now banned or restricted in several jurisdictions, due to its poor safety profile.
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".
Di(2-ethylhexyl)phosphoric acid (DEHPA or HDEHP) is an organophosphorus compound with the formula (C 8 H 17 O) 2 PO 2 H. The colorless liquid is a diester of phosphoric acid and 2-ethylhexanol . It is used in the solvent extraction of uranium , vanadium and the rare-earth metals .
