Vanadium trichloride

Vanadium trichloride (CAS 7718-98-1) is an inorganic vanadium salt used primarily as a catalyst precursor in industrial chemical synthesis.

Where is Vanadium trichloride used?

• Polymer manufacturing: production of ethylene-propylene copolymers such as EPM and EPDM rubbers
• Catalyst systems: building block for Ziegler-Natta and related coordination catalysts
• Olefin polymerization: precursor for vanadium-based homogeneous catalysts
• Specialty chemical research: starting material for other vanadium compounds and coordination complexes
• It delivers active vanadium(III) centers that initiate and control polymerization reactions.

Good to know: Precise catalyst activity affects molecular weight distribution and product consistency, particularly where narrow polydispersity is required. Moisture-sensitive packaging and careful handling are needed to maintain integrity and performance.
