|This page lists technologies that are complex, and usually major parts of
the modern DuPont Company.
There may already be established licensing practices and / or arrangements in place for
these technologies. In some cases there are restrictions on licensing these technologies
that should be discussed early in the due diligence process.
Special contacts have been arranged to provide appropriate response to requests for
technology and an expedited review of licensing opportunities.
DuPont's process technology for the production of acrylonitrile (ACRN), based on over 40 years of refinement and optimization, has a demonstrated history of improved product quality, higher operating efficiency and reduced capital cost. Acrylonitrile is used in the production of acrylic fibers and acrylonitrile-butadiene-styrene and has a projected worldwide growth rate of 2-4% per year. more...
During its 60 year history of mononitrobenzene(MNB)/aniline production, DuPont has continuously refined and optimized the process technology of this offering, particularly in the areas of process yields, energy consumption, waste minimization, product quality and high operating efficiency. Major uses of product grade aniline include polyurethane manufacture, rubber chemicals, dyes and pigments, agrochemicals and specialty fibers. more...
This sodium cyanide manufacturing process produces superior product and is unsurpassed in safety and cost effectiveness. Over 40 years of commercial manufacture has refined the operating procedures. This proven operation combined with a unique equipment configuration result in high quality product (greater than 99% solid sodium cyanide), high chemical yield, and demonstrated low maintenance costs. more...

This technology represents state-of-the-art manufacturing of mono, di, and tri methylamine derivatives --- an economical source of basic organic nitrogen and methylamino radicals. This high yield and uptime process has low operating labor requirements, technical support, and fixed costs. more...
Over five decades of operating experience are captured in the distributed control system for manufacturing monomethylformamide (MMF) and dimethylformamide (DMF). This reduces to routine practice the significant technical improvements for higher yields, capacity, and overall uptime. more...
This "green" technology, Petretec(sm), recycles all forms of polyester, "unzipping" it into monomers suitable for repolymerization or other uses. It avoids environmentally intrusive landfill or incineration. The monomers are FDA approved for all end-uses including food contact applications. Quality is equivalent to virgin monomers. Feedstocks include cotton blends, resins, films, belts, fibers, etc. This technology has been commercially demonstrated, and is particularly well suited to operate integrated with standard PET polymerization facilities using the DMT synthesis route. more...
Shorter cycle times and lower cost evaluations of carcinogens and cancer treatments are enabled by this technology for producing test eukaryotic animals (preferably rodents such as mice) that have transgenic modifications to increase their susceptibility to neoplasm development. more...
