Mgbe ọdịnala antioxidant phenolic na nitrogen na ikuku oxygen dị na ikuku, ọ na -emepụta ihe quinone. Ọdịdị Qinone bụ ihe na -akpata odo odo na acha ọbara ọbara.

A na -ejikwa antioxidant Phosphite n'ọtụtụ ebe dị ka ezigbo antioxidant inyeaka. Agbanyeghị, site na mmụba na -aga n'ihu nke ụkpụrụ nchekwa gburugburu ebe obibi EU, ihe ndị chọrọ antioxidant phosphite na -adịwanye elu. Ekwesịrị ka antioxidant Phosphite bụrụ enyi na gburugburu ebe obibi, anaghị egbu egbu, na-abụghị phenolic, na-eguzogide hydrolysis, ma na-eguzogide oke okpomọkụ.

Antioxidant inyeaka nke Phosphite bụ otu n'ime ihe mgbakwunye nkwụsi ike polymer kacha arụ ọrụ na 1990s. N'ime afọ iri, ụdị ihe owuwu ọhụrụ na -apụta na enweghị njedebe, mana site na usoro kemịkalụ ha, anyị nwere ike chọpụta na usoro ọhụrụ nke phosphite nwere mgbanaka aromatic na -agbanwe agbanwe, na nke ka ukwuu bụ pentaerythritol diphosphite spiral ring structure na bisphenol phosphite ester structure. Ọ pụtara na mmepe teknụzụ phosphate ester inyeaka antioxidant kwesịrị ilekwasị anya n'akụkụ abụọ: otu esi emezi nkwụsi ike nke igwe na otu esi emezi nkwụsi ike hydrolytic.

Ihe antioxidant anyị na -abụghị phenolic -AN333 & AN340, enweghị usoro phenolic, yabụ ọ nwere ike zere nsogbu odo odo nke usoro quinone kpatara. Ọnọdụ nhazi nwere ike ịdị elu karịa 180 ℃, ọtụtụ ndị ahịa nọ na mba ofesi etinyere ya na PU, PVC na ubi ndị ọzọ.

N'ime ha, AN333 egosila na ọ na -eme nke ọma na ihe ụfụfụ PU, yana ezigbo nguzo odo na ezigbo nguzogide hydrolysis. Ọ bụ nnọchi kacha mma JOHOKU Chemical JP333E.
