Polymerisation reactor used for the production of styrene butadiene rubber (SBR) is made of__________________?
Correct answer: D. Stainless steel or glass lined vessel
- A. Cast iron
- B. Wrought iron
- C. Karbate
- D. Stainless steel or glass lined vessel
Explanation
SBR polymerisation reactors commonly use stainless steel or glass-lined construction because these materials resist corrosion and contamination from the reaction mixture. Ordinary cast iron and wrought iron are less suitable for this service.
