Cyclododecatrienes are cyclic trienes with the formula C12H18. Four isomers are known for 1,5,9-cyclododecatriene. The trans,trans,cis-isomer is a precursor in the production of nylon-12.

==Production== The trans,trans,cis-isomer is obtained by cyclotrimerization of butadiene catalyzed by a mixture of titanium tetrachloride and an organoaluminium co-catalyst. Production capacity in 1995 was 8000 tons. thumb|class=skin-invert-image|left|304px|Route to cis,trans,trans-CDT from butadiene
