2-Propylheptanol Production Process - Cost Analysis - 2-PH E11A

Book excerpt: This report presents a cost analysis of 2-Propylheptanol (2-PH) production from butenes and syngas. The process examined is similar to the LP OXO technology jointly licensed by Johnson Matthey Davy and Dow. This process involves three main steps: hydroformylation of butenes to valeraldehyde (pentanal), aldolization of valeraldehyde to Propyl-2-heptenal; hydrogenation of Propyl-2-heptenal to 2-PH, which is then submitted to a fractional distillation for separation of both light and heavy impurities. This report was developed based essentially on the following reference(s): (1) "OXO Synthesis", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition (2) US Patent 5001274 issued to Union Carbide (now Dow Chemical Company) in 1991 (3) WO1993020034 issued to Davy (now subsidiary of Johnson Matthey) in 1993 Keywords: Oxo Alcohol, Johnson Matthey, Dow, LP OXO
