AMHERST, Mass. – Chemical engineering researchers Wei Fan, Paul Dauenhauer and colleagues at the University of Massachusetts Amherst report this week that they’ve discovered a new chemical process to make p-xylene, an important ingredient of common plastics, at 90 percent yield from lignocellulosic biomass, the highest yield achieved to date. Details are in the current issue of Green Chemistry.
As Dauenhauer explains, the chemical industry currently produces p-xylene from more expensive petroleum, while the new process will make the same chemical from lower-cost, renewable biomass.
