DUPONT SAYS IT HAS DEVELOPED A third-generation catalyst system for its butadiene-to-adiponitrile (ADN) process and is ready to commercialize the technology at the company's 50-50 Butachimie joint venture with Rhodia at Chalampe, France. "Most of our research dollars in nylon intermediates are going into ADN," says Jeffrey R. Crudgington, global marketing director/nylon intermediates at DuPont.

The third-generation catalyst "is very, very cost effective, much more active and more robust than the current systems, and results in process simplifications, as well as energy reduction," says Crudgington.
