        補充資料:自氧化作用
        分子式:
        CAS號:

        性質:又稱自動氧化。物質在常溫或中等溫度(一般低于150℃)下緩緩與氧作用的一種自發的但不發生燃燒的氧化過程。加熱,光照促進該過程。避光,低溫則減緩該過程。通常會涉及自由基反應機制,最為典型的是不飽和脂肪酸的雙鍵碳原子在脂氧化酶(廣泛存在的一種含鐵酶)作用下,先被空氣中的氧氧化,產生自由基、過氧化物和氫過氧化物并伴隨碳鏈斷裂等。還產生大量衍生物,引起油脂或含油脂食品酸敗、變質。此外,高分子聚合物長期暴露于陽光下引起的降解、植物油的干燥、潤滑油之樹膠化也與此有關。工業上有時也可利用自氧化作用,如苯酚和丙酮即可通過對異丙基苯自氧化來制取。
