REACTIONS OF CYCLOPROPANE AND 1-BUTENE OVER REDUCED MOLYBDENA-ALUMINA CATALYSTS

The metathesis and isomerization of cyclopropane were studied over a series of reduced molybdena - alumina catalysts ( % Mo within 1.4 - 11.3 %). The influence of the high temperature reversibly adsorbed hydrogen (Hr) was studied, by changing the evacuation temperature prior to the reaction. Both transformations were severely hindered by the presence of Hr. The isomerization and metathesis of 1-butene were carried out for comparison purposes. In this case, the isomerization rate increased while the metathesis reaction rate decreased, in the presence of Hr. The results are discussed in terms of the current literature.
