Usage

General Description

TRIS(4-HYDROXYPHENYL)PHOSPHINE OXIDE, also known as THPPO or Tris(4-hydroxyphenyl) phosphine oxide, is a chemical compound that is commonly used as a photoinitiator in the polymerization of radical curing systems. It is a white to pale yellow solid with the chemical formula C18H15O4P. THPPO is highly efficient in initiating the polymerization of acrylate monomers when exposed to ultraviolet or visible light. It has low volatility and is stable under normal storage and handling conditions. THPPO is also used as a stabilizer in various polymers and as a photoinitiator in dental materials, adhesives, and coatings.

Preparation method of high-reproducibility tris(4-carboxybiphenyl)phosphine

The invention relates to the technical field of organic methodology, and relates to a preparation method of high-reproducibility tris(4-carboxybiphenyl)phosphine. The preparation method comprises thefollowing steps: reacting a hydroxyl-substituted phosphorus precursor with p-toluenesulfonyl chloride to form a compound, and carrying out a Suzuki coupling reaction on the compound to obtain anmethylester compound of a pentavalent phosphorus ligand; and carrying out chlorosilane reduction and hydrolysis to obtain the high-purity tris(4-carboxylbiphenyl)phosphine. The preparation method of tris(4-carboxyl biphenyl)phosphine has high reproducibility, and avoids using of butyl lithium and other high-risk organic reagents to synthesize brominated precursors. The preparation method of tris(4-carboxyl biphenyl)phosphine is high in yield and suitable for large-scale production.
