The Monsanto process is an industrial method for the manufacture of acetic acid by catalytic carbonylation of methanol. [1] The Monsanto process has largely been supplanted by the Cativa process, a similar iridium-based process developed by BP Chemicals Ltd, which is more economical and environmentally friendly.
The primary use of acetic acid is the production of vinyl acetate monomer (VAM). In 2008, this application was estimated to consume a third of the world's production of acetic acid. [27] The reaction consists of ethylene and acetic acid with oxygen over a palladium catalyst, conducted in the gas phase. [49]
Celanese operates 25 production plants and six research centers in 11 countries, mainly in North America, Europe, and Asia. The company owns and operates the world's three largest acetic acid plants: one in the Clear Lake area of Pasadena, Texas, [6] one on Jurong Island in Singapore, and a third in Nanjing, China.

Acetic acid bacteria (AAB) are a group of Gram-negative bacteria which oxidize sugars or ethanol and produce acetic acid during fermentation. [1] The acetic acid bacteria consist of 10 genera in the family Acetobacteraceae. [1] Several species of acetic acid bacteria are used in industry for production of certain foods and chemicals. [1]
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. [1]: 293–307 The process is based on an iridium-containing catalyst, such as the complex [Ir(CO) 2 I 2] − (1).
Industrial fermentation is the intentional use of fermentation in manufacturing processes. In addition to the mass production of fermented foods and drinks, industrial fermentation has widespread applications in chemical industry. Commodity chemicals, such as acetic acid, citric acid, and ethanol are made by fermentation. [1]
A second Eurochem facility, Novomoskovskiy Nitrogen sent nearly 5,000 metric tons of nitric acid to Sverdlov in the same period, the railway data showed. Both acetic acid and nitric acid are used ...
The acetic acid it generates is used in the manufacturing of acetate rayon, plastics production, rubber production, and photographic chemicals. In addition to its industrial applications, A. aceti's unique metabolic capabilities have gained attention in biotech research. Studies have found that it has the potential to be a key player in the ...
