Antioxidant 168 CAS 31570-04-4 yog dab tsi?

Antioxidant 168 yog ib qho zoo heev phosphate ester antioxidant nrog cov hmoov dawb zoo li. Nws yog yooj yim soluble nyob rau hauv organic solvents xws li benzene, chloroform, thiab cyclohexane, me ntsis soluble nyob rau hauv ethanol thiab acetone, insoluble nyob rau hauv polar solvents xws li dej thiab cawv, thiab me ntsis soluble nyob rau hauv esters. Tsawg toxicity, tsawg volatility, siab thermal stability, zoo heev hydrolysis tsis kam, thiab zoo decomposition ntawm hydroperoxides generated thaum thermal ua ntawm polymer cov ntaub ntawv.
