1,4- dioxin, p- dioxin, is a heterocyclic oxygen-containing organic compound as an annularly closed double ethers of dihydric alcohol Ethendiol (HO- CH = CH- OH) can be considered as an oxygen- or heterocyclic of cyclohexadiene: 1.4 -dioxa -2 ,5- cyclohexadiene. In addition to 1,4- dioxin isomer 1,2- dioxin exists (o- dioxin ).

From the structure of dioxin and furan of chemically related to the toxic, carcinogenic and durable polychlorinated dibenzodioxins and -furans derived. The term dioxin is used very often outside the art for this class, which also includes the so-called Seveso 2,3,7,8- tetrachlorodibenzodioxin (TCDD ) is one that has been released during the chemical accident in Seveso, the Sevesounglück.

Production and representation

1,4- dioxin can by cycloaddition, more precisely by epoxidation and subsequent cycloreversion of the Diels -Alder adduct of maleic anhydride and furan are presented.
