Terephthalic acid is a difunctional acid used in the preparation of PET polymer.
Under similar conditions, the solubility of terephthalic acid in water is less than that of paraxylene.
Benzene, ethylene glycol, and gasoline are obtained from the crude oil distillation process.
The molecular chain of polypropylene, like polyethylene, is unbranched.
