2,2-Bis(2-Hydroxy-5-biphenylyl)propane - Introduction

Bisphenol OPPA(Bisphenol OPPA) is an organic compound containing two phenolic groups. Its chemical structure contains two benzene rings connected by a two-carbon bridge. The common structural formula of Bisphenol OPPA is OPPA (tert-butyl 2,2-bis (4-hydroxyphenyl) propionate).

The main properties of Bisphenol OPPA include:
-Appearance: White crystalline solid
-Solubility: Soluble in organic solvents such as methanol, ethers, etc
-Melting point: About 180-185 degrees Celsius
-Thermal stability: stable at high temperature, not easy to decompose

The main use of Bisphenol OPPA is as a chemical intermediate, used in the manufacture of polymer materials, including resins, plastics, etc. It can be used to synthesize polyester resins, which have good heat resistance, electrical insulation and mechanical properties, and are widely used in plastic products, electronic products, auto parts and other fields.

The method of preparing Bisphenol OPPA can be obtained by the acid-catalyzed reaction of phenol with tert-butyl acryloyl propionate. Specific steps include polycondensation of phenol and tert-butyl acryloyl propionate, followed by acid catalysis and esterification.

Regarding the safety information of Bisphenol OPPA, the following points should be noted:
- Bisphenol OPPA is an organic compound. Avoid contact with skin and eyes. Wear protective gloves and goggles when using it.
