21117-79-3 - Introduction
PHAP(PHAP), the chemical formula is C24H16O8. The following is a description of the nature, use, preparation and safety information of PHAP:
Nature:
- PHAP is a colorless to light yellow solid crystalline substance.
-Has low solubility, soluble in organic solvents such as chloroform, dimethylformamide and toluene.
-Stable in air, but may decompose at high temperatures.
Use:
- PHAP has good thermal stability and optical properties, so it is widely used in the field of optical materials, such as optical fibers and touch screens.
-Can also be used as industrial chemicals such as high temperature lubricants and plasticizers.
Method:
The synthesis of-PHAP generally involves the reaction of terephthalic anhydride with 3,4-dihydroxybenzaldehyde to form the intermediate 3,4-Dihydroxybenzoic acid alcohol.
-Then, through an esterification reaction, 3,4-Dihydroxybenzoic acid alcohol is reacted with benzoic acid anhydride to finally obtain PHAP.
Safety Information:
- PHAP has limited toxicity information, but as a chemical substance, it is still necessary to pay attention to safe operation.
-During operation, it is recommended to wear appropriate protective equipment, such as chemical protective gloves and goggles.
-avoid PHAP contact with skin and eyes, if contact, immediately rinse with plenty of water.
-When storing, please store PHAP in a cool and dry place, away from dangerous substances such as fire sources and oxidants.
