Teryleneisa condensation polymer of ethylene glycol and which acid? (1) Benzoic Acid (2) Salicylic acid (3) Phthalic acid (4) Terephthalic acid
by

1 Answer

Answer :

(4) Terephthalic acid Explanation: Terylene is a co-polymer of ethylene glycol and Terephthalic acid. Also known as Dacron, it is prepared by the condensation polymerization of ethylene glycerol and. Terephthalic acid with elimination of water. The reaction is carried out at about 420- 460 K in the presence of a catalyst consisting of a mixture of zinc acetate and antimony trioxide.

(3) prevents freezing of petrol Explanation: Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound widely used as an automotive antifreeze and a precursor to polymers. In its pure form, it is an odorless, colourless, syrupy, sweettasting liquid. Ethylene glycol is toxic, and ingestion can result in death. Due to its low freezing point ethylene glycol resists freezing. A mixture of 60% ethylene glycol and 40% water freezes at -45 degree C (- 49 degree F).
