2) One of the most common consumer plastics is PET (polyethylene terephthalate), which is used extensively in containers for food and beverage products. Coca-Cola has recently come up with a biobased source of ethylene glycol for synthesizing this polymer, however, the terephthalic acid is still derived from petroleum sources. A sustainable source of terephthalic acid is therefore highly desired. One candidate is 2,5-furandioic acid. Draw the repeat unit for the resulting sustainable polyester derived from 2,5furandioic acid and ethylene glycol.

12. A way to produce a highly cross-linked polyester is to use glycerol. Alkyd resins are a polymer of this type. The polymer forms tough coatings when baked onto a surface and is in used in automobile paints and large appliances. Draw the structure of the polymer formed from the condensation of one glycerol and three phthalic acid molecules: H₂C-CH-CH₂ COH OH OH OH + сон Glycerol phthalic acid
The plastic known as PETE (polyethyleneterephthalate) is used to make plastic soft drink bottles and containers for salad dressing, shampoos, and dishwashing liquids. PETE is a polymer of terephthalic acid and ethylene glycol. Today, PETE is the most widely recycled of all the plastics. After it is separated from other plastics, PETE can be used in polyester fabric, door mats, and tennis ball containers. In 2015, 1.84×109 lb1.84×109 lb of PETE bottles were recycled in the U.S. The density of PETE is 1.38 g/mLg/mL. How many kilograms of PETE bottles were recycled in 2015 in the U.S.? Express your answer to three significant figures.
