  • Olefin metathesis by reactive distillation
    Patent number: 11820740
    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.
