Chemical Properties

CLEAR VERY SLIGHTLY YELLOW TO PINK LIQUID

General Description

Wax. When mixed with its isomers (ortho and meta ), the result is a colorless, odorless liquid.

Air & Water Reactions

May hydrolyze under alkaline conditions. . Insoluble in water.

Reactivity Profile

Organophosphates, such as TRI-M-TOLYL 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.

Diphenyl Diselenide-Catalyzed Synthesis of Triaryl Phosphites and Triaryl Phosphates from White Phosphorus

Industrially important triaryl phosphites, traditionally prepared from PCl3, have been synthesized by a diphenyl diselenide-catalyzed one-step procedure involving white phosphorus and phenols, which provides a halogen- and transition metal-free way to these compounds. Subsequent oxidation of triaryl phosphites produces triaryl phosphates and triaryl thiophosphates. Phosphorotrithioates are also prepared efficiently from aromatic thiols and aliphatic thiols.

Polymer supported reagents: An efficiant and simple method for the synthesis of triaryl phosphates

The reaction of phosphoryl chloride with insoluble polymer-supported phenoxide ion reagents in benzene at room temperature, produced triaryl phosphates in excellent yields. The isolation of pure products by simple filtration and evaporation is an important feature of this method.
