Correct answer: B. As plasticisers
- A. In making PVC
- B. As plasticisers
- C. In insecticides manufacture
- D. For making nylon-6
Explanation
Phthalic anhydride is mainly used to manufacture phthalate plasticisers, such as dioctyl phthalate, which are added to polymers to increase flexibility. It is not the monomer used for nylon-6 or PVC production.
