The chlorinator used in the manufacture of DDT is made of___________________?
Correct answer: C. Glass lined steel
- A. Glass
- B. Teflon
- C. Glass lined steel
- D. Bakelite
Explanation
The chlorinator handles highly corrosive chlorine and chlorinating mixtures, so glass-lined steel provides corrosion resistance together with the mechanical strength of steel. Plain glass is too fragile for a large process vessel, while Bakelite and Teflon are not the usual vessel construction.
