Abubuwan da aka hana tare da tert-butyl (X = tert-butyl) da methyl (R = methyl CH3) a matsayin o-matsayi na ƙungiyar phenolic hydroxyl da aka hana na iya raunana ƙaƙƙarfan shinge na ƙungiyar phenolic hydroxyl da aka hana zuwa wani mataki, da hanzarta ƙimar maganin antioxidant, ta haka ne ke sa sabon tsarin antioxidant yayi tasirin da ba a zata ba. Wannan sabon tsarin da aka hana antioxidant phenols an kira shi asymmetric hanawa phenols antioxidant.
Tsarin asymmetric ya hana tsarin phenolic tare da ƙungiyar tert-butyl da ƙungiyar methyl a matsayin hydroxyl ortho-matsayi ya isa ya kare kansa. Asymmetric ya hana antioxidant phenolic, tare da 2 - methyl - 6 - manyan butyl phenol a matsayin kwarangwal, ba wai kawai yana da halaye na gaba ɗaya na hana antioxidants na phenolic ba, har ma yana daidaitawa tare da kwanciyar hankali na antioxidant da juriya ga tasirin inuwa. Don haka yana da ƙarin bayyananniyar aiki fiye da nau'in sifar da aka hana na phenol, kuma ya dace da aikace -aikacen hadawan abu da iskar shaka.
AN245, AN1790 (kazalika da AN2777) da AO80 su ne abubuwan da aka hana hana antioxidants phenols guda uku, wanda AN245 shine mafi yawan amfani da shi tare da ƙarancin farashi.
AN 245 ya dace musamman don stereoobstructing phenolic antioxidants na kwayoyin polymers. A matsayin antioxidant, ana amfani dashi a cikin sarrafawa da haɓaka kwanciyar hankali na dindindin na polymers styrene kamar HIPS, MBS da ABS, robobi na injiniya kamar POM da PA da polyurethane. Hakanan shine mai kawo ƙarshen sarkar tasiri a cikin tsarin polymerization na PVC. Wannan samfurin ba shi da tasiri a kan halayen polymer, wanda aka yi amfani da shi don babban tasirin polystyrene, polyvinyl chloride, ana iya ƙara shi zuwa monomer kafin polymerization.
Baya ga yanayin samarwa na foda na yau da kullun, zamu iya samar da abun cikin 35% na watsawa-AN245DW. Bayan shekaru da yawa na ƙwarewar samarwa, ruwan watsawa da kamfanin mu ya samar kuma ba shi da sauƙin daidaitawa, kuma yana da sauƙin tarwatse fiye da foda, wanda shine babban maganin antioxidant da ake amfani da shi a cikin tsarin polymerization na PVC.
