Usage

Uses

p-t-Butylphenyl Diphenyl Phosphate is a compound with potential application to fire retardants, plasticizers and oils, due to its chemical composition.

Purification Methods

Purify it by vacuum distillation, and percolation through an alumina column, followed by passage through a packed column maintained at 150o to remove residual traces of volatile materials in a counter-current stream of N2 at reduced pressure [Dobry & Keller J Phys Chem 61 1448 1957].

Tert-butyl phenyl phosphate as well as preparation method and application thereof

The invention discloses tert-butyl phenyl phosphate as well as a preparation method and application thereof. The method comprises the following steps: stirring and heating tert-butylphenol and an ionic liquid catalyst, slowly dropwise adding phosphorus oxychloride, heating and preserving heat after dropwise adding, then adding phenol for heating reaction, adding an organic solvent into the reaction liquid after the reaction is finished, then washing and carrying out phase separation; and removing the organic solvent through reduced pressure distillation to obtain a target product. According to the preparation method, the ionic liquid is used as the catalyst, compared with traditional catalysts such as Lewis acid and solid acid, the target product with higher purity can be catalytically synthesized, the process is simple, and the requirement for industrial production is met.

Metal-free synthesis of biarenes via photoextrusion in di(tri)aryl phosphates

A metal-free route for the synthesis of biarenes has been developed. The approach is based on the photoextrusion of a phosphate moiety occurring upon irradiation of biaryl- A nd triaryl phosphates. The reaction involves an exciplex as the intermediate and it is especially suitable for the preparation of electron-rich biarenes.
