多氯雙苯並對二噁英

多氯代雙苯並對二噁英(polychlorinated dibenzo-p-dioxins)是對二噁英(對二衍生物中最重要、危害最大的一類,是二苯並對二噁英的氯代物,一般提到「二噁英」時指的均是對二噁英衍生物中的此一子類,包含臭名昭著的橙劑雜質2,3,7,8-四氯雙苯環二噁英(2,3,7,8-TCDD)。

多氯雙苯二噁英一般結構鍵線圖,注意此jargon圖中支出的氯用於取代苯環上的氫而不是去與苯環中央的共振電子雲去共享電子(那做不到)

化合物列表

 
二苯並對二噁英的取代位編號示意圖,由於5位和10位被氧給雜了,至多可以有八個氫被代。在2,3,7,8上用四個氯取代即是著名的2,3,7,8-四氯雙苯環二噁英

二苯並對二噁英含有兩個苯環和兩個氧橋,形成芳香二醚。命名中的「二噁」指

由於二苯並對二噁英的5位和10位被氧給雜了,至多可以有八個氫被代。存有凡75種多氯雙苯並對二噁英的(不同分)異構體。[1]
