| titleOfInvention | Process for the production of monocarboxylic acid anhydrides |
| abstract | Acetic anhydride is produced by reaction of dimethyl ether or methyl acetate with carbon monoxide and a catalyst containing a cobalt component and a promotor system comprising an iodide or bromide and quaternary nitrogen or phosphorus, the quaternary nitrogen or phosphorus having been formed in the reactor be the addition of two components, the first being a quaternisable trivalent nitrogen or phosphorus compound, the second being a quaternising agent, the atomic ratio of iodide or bromide to cobalt being at least 5:1 and wherein hydrogen, if present, is in an amount such that its partial pressure is not more than 20% of the total pressure of carbon monoxide and hydrogen. |
