| titleOfInvention | Method for preparing 1,5,9-cyclododecatriene |
| abstract | The invention provides a method for preparing 1,5,9-cyclododecatriene. The method comprises the steps that: in an organic solvent, a catalytic system composed of sesqui-alkyl aluminum chloride, TiX4 and at least one compound with a structure represented below is adopted, such that 1,3-butadiene is polymerized into 1,5,9-cyclododecatriene under catalysis. The X in the TiX4 is independently F, Cl, Br or I; R and R' are independently C1-C5 straight-chain alkyl or alkyl with free branched-chain. With the method provided by the invention, 1,3-butadiene is highly selectively converted into 1,5,9-cyclododecatriene, and is especially highly selectively converted into trans,trans,cis-1,5,9-cyclododecatriene. Through refining, fine 1,5,9-cyclododecatriene with purity higher than 99% can be obtained. Therefore, the method has important industrial application prospect. |
