Adipic Acid Production from Cyclohexane - Cost Analysis - Adipic Acid E11A

Book excerpt: This report presents a cost analysis of Adipic Acid production from cyclohexane The process examined is a two-stage oxidation process, similar to the Invista technology. In this process, cyclohexane is initially oxidized with air to produce KA oil (mixture of cyclohexanone and cyclohexanol). Subsequently, the KA oil is oxidized with nitric acid to produce Adipic Acid. A mixture of adipic, glutaric, and succinic acids is generated as by-product. This report was developed based essentially on the following reference(s): (1) US Patent 20040054235, issued to DuPont in 2004 (assigned to Invista in 2004) (2) "Adipic Acid," Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition Keywords: Hexanedioic Acid, DuPont, Ketone/Alcohol Oil, Air Oxidation, Nitric Acid Oxidation, Boric Acid
