PET or polyethylene terephthalate is a polyester used to make disposable plastic water bottles. Show the diol and diacid that will be made when PET is hydrolyzed in the presence of Zn(OAc)2 (a Lewis acid catalyst). Click to Show Image Description A reaction scheme shows a bracketed polymer chain composed of repeating two-carbon segments linked through O atoms to carbonyl groups and para-substituted benzene rings. Several repeating sections are drawn, and the bracket at the right is labeled n. A horizontal arrow points right, with Zn(OAc)₂ above it and 180–190 °C below it. The arrow leads to a photograph of a clear plastic water bottle bearing an Aquafina label.
