Question

Dacron is manufactured by heating a mixture of ethylene glycol and terephthalic acid with one of the conditions given below.

• A. by heating with water at a high temperature
• B. condensation polymerisation under high pressure and at high temperature
• C. at 420-460 K in the presence of zinc acetateantimony trioxide $\left(\right(Ac{)}_{2}ZnSb{O}_3)$ catalyst.
• D. None of these

Answer 1

The correct option is C at 420-460 K in the presence of zinc acetateantimony trioxide $\left(\right(Ac{)}_{2}ZnSb{O}_3)$ catalyst.

Dacron/Teryleneis a polyester is manufactured by heating a mixture of ethylene glycol and terephthalic acid at 420-460 K in the presence of zinc acetateantimony trioxide $\left(\right(Ac{)}_{2}ZnSb{O}_3)$ catalyst.
