Catalyst used in the catalytic polymerisation is__________________?
Correct answer: B. Phosphoric acid on kieselguhr
- A. Aluminium chloride
- B. Phosphoric acid on kieselguhr
- C. Nickel
- D. Vanadium pentoxide
Explanation
Catalytic polymerisation of light olefins traditionally uses phosphoric acid supported on kieselguhr. Aluminium chloride is associated with other acid-catalysed processes, while nickel and vanadium pentoxide are not the usual polymerisation catalyst here.
