Alternative on-purpose production methods for propylene metathesis chemistry has and will continue to butene-2 ethylene + butene-2 ethylene. The effect of mgo on the wox-catalyzed metathesis reaction of cis-2-butene and ethylene was studied using a series of magnesium-tungsten oxide catalysts for the first.

Propylene is formed by the metathesis of ethylene and butene-2, and butene-1 is isomerised to butene-2 as butene-2 is consumed in the metathesis reaction.
