A team of chemical engineers led by Paul J. Dauenhauer of the University of Massachusetts Amherst has discovered a new, high-yield method of producing the key ingredient used to make plastic bottles from biomass. The process is inexpensive and currently creates the chemical p-xylene with an efficient yield of 75-percent, using most of the biomass feedstock, Dauenhauer says. The research is published in the journal ACS Catalysis. Dauenhauer, an assistant professor of chemical engineering at UMass Amherst, says the new discovery shows that there is an efficient, renewable way to produce a chemical that has immediate and recognizable use for...
