Abstract: In catalytic reaction rectification column with a diameter of 50 mm, process of synthesis cyclohexene has been investigited by acticarbon adsorb silicotungstic acid. In the recation condiations, catalyst has high activity and selectivity. In this time, the main process parameters of the liquid phase continuous distillation and gas phase continuous catalysis-rectification system and the effect of the reaction with kinds of the catalyst, rectification column diameter-high ratio, catalyst high are examined. It is shown that silicotungstic acid fixed bed catalysis rectification system has biges t producing ability , high activity and selectivity and less environmental pollution. It can be used in continuous industry production.

Key words: solid acid, catalytic rectification, cyclohexene
