Product Name:2,5-Di(tert-amyl)hydroquinone
English Name:2,5-Di(tert-amyl)hydroquinone
CAS No.:79-74-3
Aliases:2,5-Di-tert-amylhydroquinone, 2,5-Di(tert-amyl)-1,4-benzenediol, DAHQ
Molecular Formula:C16H26O2
Physical Properties:White to light yellow crystalline powder; slightly soluble in water, soluble in ethanol, acetone, ethyl acetate and other organic solvents. Melting point approximately 179-181°C, with a high boiling point and easy decomposition upon heating. Stable in air and can react with strong oxidants. As a hindered phenolic antioxidant, it exhibits excellent thermal stability and extraction resistance.
Uses:This product is a high-performance hindered phenolic antioxidant mainly used in natural rubber, synthetic rubber, and latex products, especially suitable for chloroprene rubber, styrene-butadiene rubber, and cis-polybutadiene rubber. It is also applied in plastics, adhesives, and coatings to effectively delay the thermo-oxidative aging of polymers during processing and service, thereby extending the service life of end products.
Technical Specifications:
Appearance: white to light yellow crystalline powder, free of visible mechanical impurities.
Melting point: not lower than 179°C.
Purity (HPLC): not less than 99.0%.
Heating loss (volatiles): not more than 0.5%.
Residue on ignition: not more than 0.1%.
