Title:
METHOD FOR PRODUCING CYCLODODECENE
Document Type and Number:
Japanese Patent JP2004339197
Kind Code:
A
Abstract:

To provide a gas phase method for performing a selective heteogeneous system hydrogenation from cyclododecatriene and/or cyclododecadiene (as starting materials) to cyclododecene, using a continuous method, excellent in CDEN selectivity at ≥99.5 % conversion rate (CDT+CDD), realizing the reaction in an industrial scale, without having the inferiority of conventional methods, and using an easily usable catalyst.

This method for producing cyclododecene (CDEN) by the selective gas phase hydrogenation of at least one kind of starting material selected from cyclododecatriene (CDT), cycclododecadiene (CDD) and a mixture of them in a solid bed reactor is characterized by having >100 Bodenstein number related to the processes in the solid bed reactor.
