Product description:
Molecular formula:C23H32O2
Molecular weight:340.49
Purity product appears colorless oblique square crystal,
Melting point 131.2,
density 1.07g/ml(30C).
Industry product appears white or ivory-white crystal powder,
Density 1.04-1.08,
melting point 120-130C,low volatility,steam pressure 2mm/Hg columniation (160C).In rubber,solubility exceeds 2%,in organic impregnant(such as carbinol, Alcohol, Benzene, Acetone,Ethyl acetate,Chloroform)it can well dissolve.Because of the hindered phenolic structure,its chemical character is not lively.In storage it can keep stalbe conditions.It will appear slightly red after long storage ,but have no effect on anti oxidant.
