发明名称 Process for the production of carboxylic acids.
摘要 A process for the production of a carboxylic acid or its ester by catalytic liquid phase oxidation of a corresponding precursor in acetic acid as solvent, said process comprising: (i) forming a reaction medium comprising acetic acid, oxidation catalyst, precursor and oxidant; (ii) optionally recycling methyl acetate produced from the acetic acid as a by-product back to the reaction medium; (iii) introducing additional methyl acetate and/or methanol into the reaction medium, said additional methyl acetate and/or methanol being additional to any recovered methyl acetate recycled back to the reaction medium.
