Process for the coproduction of carboxylic acids and acid anhydrides |
| abstract |
A process for the coproduction of a monocarboxylic acid and anhydride which process comprises reacting a carboxylate ester having the formula RCOOR' or ether having the formula ROR 1 , wherein R and R' are independently monovalent hydrocarbyl radicals, water and optionally also an alcohol at elevated temperature and pressure with carbon monoxide in the presence of a catalyst comprising a noble metal of Group VIII of the Periodic Table according to Mendeleef, a promoter comprising bromine or iodine in free or combined form and a co-promoter comprising a Lewis base or a non noble metal provided that when R and R' are methyl, water is added in an amount from 5.5% w/w based on the total weight of water + (ester or ether) + alcohol if present and when R is other than methyl, water is present in an amount from 5.5 mole % in any one or more of the reactants and that the maximum amount of water or equivalent of water and alcohol added in either case is 85% of the stoichiometric amount based on the ester or ether. |
