Application
9 9-Bis(3-methyl-4-hydroxyphenyl)fluorene (CAS:88938-12-9) is an important materials chemistry, which is widely used in various of industrial and scientific fields.
Its main applications are as follows:
1. 9 9-Bis(3-methyl-4-hydroxyphenyl)fluorene is a high-performance curing agent and monomer for heat-resistant epoxy resins applied in electronic packaging and PCB materials.
2. 9 9-Bis(3-methyl-4-hydroxyphenyl)fluorene is a key raw material for synthesizing polycarbonate, polyimide and other high heat-resistant engineering plastic resins.
3. 9 9-Bis(3-methyl-4-hydroxyphenyl)fluorene is a functional intermediate for preparing flame-retardant composite materials and high-temperature resistant coating binders.
Storage
1. Store the sealed solid below 25°C in a dry dark cabinet to prevent oxidation of phenolic hydroxyl groups on the benzene rings.
2. Limit frequent opening of the packaging to stop reddish discoloration triggered by oxygen and water vapor in the ambient air.
3. Keep this compound separated from strong oxidants and strong alkaline substances to avoid phenolic salt generation and molecular degradation.
Benefits Of Use
1. Dual phenolic hydroxyl groups can conduct epoxy ring-opening reaction to crosslink and cure epoxy resin systems efficiently.
2. The bulky fluorene rigid skeleton greatly improves heat resistance, glass transition temperature and dimensional stability of cured polymers.
3. Methyl substituents enhance the solubility of the monomer in common organic solvents without damaging overall thermal performance.
Safety Information
1. Block inhalation of fine crystalline powder; wear dust masks and chemical resistant gloves during weighing and material handling.
2. This substance brings mild irritation to skin and ocular mucous tissues; wash contaminated sites with sufficient running water after contact.
3. Discard waste solids and waste liquid according to hazardous waste management rules for fluorene-based bisphenol compounds.
