Abstract
A method for preparing cyclododecene and a synthesis device therefor, of the present invention, remarkably increase the conversion ratio of cyclododecatriene and selectivity of cyclododecene, can minimize the costs required for equipment and processing, are practical, reduce processing time, and are industrially advantageous to mass production in comparison with a conventional method and device.
Claims15
A method for synthesizing cyclododecene, comprising a hydrogenation step of partially hydrogenating cyclododecatriene to synthesize cyclododecene,
- wherein cyclododecatriene and hydrogen sequentially pass through a continuous stirred-tank reactor and a tubular reactor and react with each other in the continuous stirred-tank reactor and the tubular reactor to synthesize cyclododecene.
A device for synthesizing cyclododecene by partially hydrogenating cyclododecatriene, the device comprising:
- a continuous stirred-tank reactor into which cyclododecatriene and hydrogen are introduced to synthesize cyclododecene;
- and
- a tubular reactor into which the cyclododecene or a mixture including the cyclododecene is introduced from the continuous stirred-tank reactor to synthesize cyclododecene.
A device for synthesizing cyclododecene by partially hydrogenating cyclododecatriene, the device comprising:
- a first continuous stirred-tank reactor into which cyclododecatriene and hydrogen are introduced to synthesize cyclododecene;
- a second continuous stirred-tank reactor into which the cyclododecene or a mixture including the cyclododecene is introduced from the first continuous stirred-tank reactor to synthesize cyclododecene;
- and
- a tubular reactor into which the cyclododecene or a mixture including the cyclododecene is introduced from the second continuous stirred-tank reactor to synthesize cyclododecene.
