Question

Which of the following materials is used in production of terylene?

• A. PMMA
• B. DMT
• C. Glycerol
• D. Bisphenol

Hint:

PET can be synthesized using either DMT or terephthalic acid as the acid component.

Answer 1

The Correct Option is B

Step 1: Understanding terylene production.
Terylene is the trade name for polyethylene terephthalate (PET), which is produced by condensation polymerization.
Step 2: Raw materials involved.
Terylene is manufactured using dimethyl terephthalate (DMT) or terephthalic acid along with ethylene glycol. DMT reacts with ethylene glycol to form PET.
Step 3: Analysis of options.
(A) PMMA: It is itself a polymer, not a raw material for PET.
(B) DMT: Correct — A key monomer used in terylene production.
(C) Glycerol: Used in alkyd resins, not PET.
(D) Bisphenol: Used in polycarbonate synthesis.
Step 4: Conclusion.
Dimethyl terephthalate (DMT) is used in the production of terylene, hence option (B) is correct.
