The acetic acid process was developed at BASF in Ludwigshafen to plant-scale application [543, 1007, 1008, 1012]. It operates with cobalt/ iodine as catalyst and with addition of water at about 250 °C and 750 atm in the carbonylation reactor [1012].

As early as 1960 a 100% atom efficient cobalt-catalyzed industrial synthesis of acetic acid was introduced by BASF, shortly afterwards followed by the Monsanto rhodium-catalyzed low-pressure acetic acid process (Scheme 5.36) the name explains one of the advantages of the rhodium-catalyzed process over the cobalt-catalyzed one [61, 67].

2020年1月1日 · Later, Reppe and his research group in I.G. Farben, and then BASF, patented the catalytic activity of iron, cobalt and nickel in the presence of an iodide copper salt to carbonylate methanol to acetic acid and methylacetate, most examples being focused on nickel at 230–340 °C and 180–200 bar [8].

Among various chemical routes, the most common industrial AA synthesis method is carbonylation of methanol (MeOH), where AA is produced through different processes such as BASF, Cativa, and...

In this chapter we discuss the mechanistic and other details of a few industrial carbonylation processes. These are carbonylation of methanol to acetic acid, methyl acetate to acetic anhydride, propyne to methyl methacrylate, and benzyl chloride to phenyl acetic acid.

2010年1月1日 · The production of acetic acid by carbonylation of methanol (Equation (1)) can also be traced back to the 1950s when Reppe and coworkers at BASF developed a cobalt iodide catalyst that was effective for this reaction at relatively high temperatures and pressures (~ 250 °C, 600 bar) [1], [2].

BASF prepared the a way for new acetic acid process with their work on the catalytic conversion of CO and H 2. It was discovered around 1913 that methanol, the primary reaction product from synthesis gas, could be carbonylated to acetic acid. This route became economically feasible after 1920 when methanol was available in commercial quantities.

2022年9月20日 · Monsanto, in the middle 60s, improved BASF process, obtaining excellent acetic acid selectivity (99%) under milder conditions, around 30–60 bar and 150–200 °C. The Monsanto process involves the use of homogeneous methyl iodide-promoted rhodium-based catalyst in the system, which improves the catalytic activity obtained with the cobalt ...

One of the most important bulk commodity chemicals, acetic acid is now produced via methanol carbonylation reactions using homogenous organometallic complexes of rhodium or iridium and...
