Abstract: Processes and reaction systems for olefin metathesis by reactive distillation, utilizing liquid phase metathesis of reactant olefins in the presence of a homogeneous metathesis catalyst system, where the light metathesis product is produced and leaves the liquid phase as vapor phase and the heavy metathesis product is produced in liquid phase. Separation can be performed on the light metathesis product and a distinct other separation can be performed on the heavy metathesis product.

Abstract: Metathesis of olefins in a loop reactor having liquid reaction medium circulated therein that contains reactant olefins and homogeneous metathesis catalyst system in liquid phase. Recovery of product olefin(s) occurs after removing a liquid reactor effluent from the loop reactor, and unreacted reactant olefin(s) recovered from the liquid reactor effluent can be recycled to the loop reactor.
