DuPont aniline manufacture

Drawing on the Allied technical reports, ICI in England began the manufacture of diisocyanates. Production of polyurethanes in the US started in 1954, and by the following year they were available on a commercial scale as adhesives, coatings, foams and elastomers. The main American manufacturers of the intermediate isocyanates were DuPont, Mobay (a joint venture of Mobil and Bayer) and National Aniline. [Pg.62]

Spandex stretch fiber, based on polyurethanes, was developed by DuPont and appeared in 1962. From this time, polyurethanes would account for the greater part of demand for anilines. Aniline production alone had more than doubled, to over 100 million lbs. per year, between 1939 and 1957, in part to satisfy demand in products other than dyes. Half the US output was consumed in the production of rubber additives, mainly diphenylamine and cyclohexylamine, the latter used as a chain stopper in manufacture of polyurethanes (also as a boiler water additive and, in the US until banned in 1970, in the manufacture of cyclamate sweeteners). Other polymers, such as epoxy resins, relied on the bulk availability of various aromatic amines (Chapter 14). [Pg.63]

Aniline is the second largest petrochemical use of gaseous hydrogen. About half as much hydrogen is used for aniline as for cyclohexane production. Approximately 80% of the aniline produced worldwide is used in the manufacture of MDI for polyurethanes. The balance is used for rubber processing chemicals, agricultural chemicals, dyes, pigments, pharmaceuticals, and specialty polymers. DuPont s aromatic polyamide fiber Kevlar is also derived from aniline [1). [Pg.200]
