Usage

General Description

Tris(4-chlorophenyl) phosphate, also known as TCPP, is a chemical compound commonly used as a flame retardant in various products such as plastic, foam, and textiles. It is a clear to pale yellow liquid with a mild aromatic odor. TCPP works by reducing the flammability of materials and delaying the spread of fire by releasing gases that interfere with the combustion process. However, TCPP has been linked to potential health and environmental concerns, including toxicity and persistence in the environment. As a result, there are ongoing efforts to minimize the use of TCPP and find safer alternatives for flame retardant applications.

Aerobic Oxidation of Phosphite Esters to Phosphate Esters by Using an Ionic-Liquid-Supported Organotelluride Reusable Catalyst

We describe the synthesis of an ionic-liquid (IL)-supported organotelluride catalyst and its application as a recyclable catalyst for the aerobic oxidation of phosphite esters to phosphate esters. This method shows high conversion rates, allows the ready isolation and purification of the resulting products, and exhibits good reusability of the catalyst.

"One-pot" Synthesis of Triaryl Phosphates a Reaction Calorimetry Approach

Triaryl phosphates were obtained in yields ranging from 85-96percent in a "one-pot" synthesis via an alkaline route: an ethanolic solution of sodium hydroxide was added to a solution of substituted phenol in toluene.The mixture was distilled until all ethanol was removed.Phosphorus oxychloride was then added and the toluene was distilled.The triaryl phosphates were characterized by NMR (1H and 31P), MS and FTIR.The heat capacity (Cp), the total heat transfer coefficient (U) and the reaction enthalpy (ΔH) were determined for the synthesis of tris(4-chloro-3-methylphenyl), tris(p-cresyl), tris(o-methoxyphenyl) and tris(p-nitrophenyl) phosphates. - Keywords: Phosphate; NMR spectra; heat capacity; phosphorus oxychloride
