How is terylene or dacron prepared? – InterviewSolution

1.	How is terylene or dacron prepared?
Answer» Solution :Terylene is a polyester FIBRE FORMED by the POLYMERISATION of dimethyl terephthalate with ETHYLENE glycol. Dimethyl terephthalate is heated with ethylene glycol at 503 K in the presence of zinc acetate and antimony trioxide as a catalyst when dihydroxydiethyl terephthalate (monomer) is formed, Dihyd- roxydiethyl terephthalate on heating polymerises to give terylene.
