WebPatented June 5, 1945 UNITED STATES PATENT OFFICE SYNTHESIS OF ADIPONITRILE No Drawing. Application January 18, 1944, Serial No. 518,741. 7 Claims. This invention relates to the synthesis of adiponitrile from adipic acid and a nitrile of an allphatic acid and more particularly to its synthesis from adipic acid and acetonitrile. Almost all adiponitrile is hydrogenated to hexane-1,6-diamine for the production of nylon: NC(CH2)4CN + 4 H2 → H2N(CH2)6NH2 Like other nitriles, adiponitrile is susceptible to hydrolysis; however, the resulting adipic acid is less expensively prepared via other routes. See more Adiponitrile is an organic compound with the chemical formula (CH2)4(CN)2. This viscous, colourless dinitrile is an important precursor to the polymer nylon 66. In 2005, about one million tonnes of adiponitrile were produced. See more In 2024, there existed approximately 1.5 million metric tons of capacity. The main producers of adiponitrile were: • Ascend … See more • International Chemical Safety Card 0211 • NIOSH Pocket Guide to Chemical Hazards. "#0015". National Institute for Occupational Safety and Health (NIOSH). • www.chemicalland.com See more Early methods Because of the industrial value of adiponitrile, many methods have been developed for its synthesis. Early industrial methods started from See more The LD50 (median lethal dose) of adiponitrile is 300 mg/kg for oral ingestion by rats. In 1990, See more
