Chemists have invented a method to selectively prepare p-xylene from only ethylene (J. Am. Chem. Soc., DOI: 10.1021/ja307612b). The achievement creates an opportunity to make the commodity chemical terephthalic acid and its blockbuster derivative polyethylene terephthalate (PET) from alternatively sourced p-xylene. p-Xylene is typically produced by catalytic reforming of various crude oil streams in refineries. Using ethanol from biomass or ethane from shale gas would reduce reliance on crude . . .
