ABSTRACT:
A method for carrying out continuous olefin (e.g., the conversion of 1,7-octadiene into cyclohexene and ethylene) ring-closing metathesis is described where compressed carbon dioxide (gaseous, liq., or supercrit.) is used as a solvent for the liq. or solid reactant and the products produced. One or more ionic liqs. are addnl. introduced as the second phase in which the homogeneous Ru-complex olefin metathesis catalysts are immobilized; a process flow diagram is presented. |
