[PDF] cativa process kinetics

  • What is the Cativa process?

    The Cativa process is a method for the production of acetic acid by the carbonylation of methanol.
    The technology, which is similar to the Monsanto process, was developed by BP Chemicals and is under license by BP Plc.
    The process is based on an iridium-containing catalyst, such as the complex [Ir(CO)2I2]? (1).

  • What are the reaction conditions for the Cativa process?

    Reaction conditions: 190°C, 22 barg, and 1500 rpm.
    Autoclave charge: methyl acetate (648 mmol), water (943 mmol), acetic acid (1258 mmol), methyl iodide (62 mmol), and H2IrCl6 (1.56 mmol) plus additive as required.

  • What is the yield of the Cativa process?

    The Cativa process resulted in good yields of acetic acid (85%) and methanol (58%) (13) .

  • What is the yield of the Cativa process?

    In 1996, BP Chemicals announced a new methanol carbonylation process, Cativa,5 based upon a promoted iridium/iodide catalyst, which now operates on four plants worldwide.17 fév. 2004
