Phosphate ester 뜻
WebPhosphate esters are the most fire resistant of the non-aqueous synthetic basestocks in common use. Their high ignition temperatures, excellent oxidation stability and very low vapor pressures make them difficult to burn, while their low heats of combustion result in self-extinguishing fluids.

WebPhosphate esters are ubiquitous in nature and essential to life, where their chemistry reaches a state of near-perfection. Although industrial chemistry is not nearly as sophisticated, industrial chemists have managed to adapt the phosphation process and starting material structures to produce a wide range of commercially valuable products. WebPhosphite 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 (scheme). In this process the phosphite is converted to a phosphate ester. This reaction type is also utilized in the Wender Taxol total synthesis.

WebIn phosphate esters, diesters, and anhydrides the pi bonding is delocalized primarily over the non-bridging bonds, while the bridging bonds have mainly single-bond character. In a phosphate diester, for example, the two non-bridging oxygens share a -1 charge, as illustrated by the two major resonance contributors. In the resonance contributors ...
