| Abstract: | The paper studies the rules governing the synthesis of 1,5,9-cyclododecatriene with toluene as solvent and TiCl_4-Al(C_2H_5),Cl_(3-x)-OS(CH_3)_2 as catalyst.It investigates the range of catalyst components ratio as well as the preferred reaction conditions.A pilot plant study has been carried out. Product purity is>99.7％,catalyst efficiency>19kg/gTi,and selectivity>90％。Also discussed in the paper are the effects on catalyst activity and selectivity of solvent quantity, reaction time,catalyst moisture content and methods of addition of butadiene. |
