| titleOfInvention | Process for preparing carboxylic acids by carbonylation |
| abstract | 1. Process for the preparation of a monocarboxylic acid by carbonylating an alcohol, in the liquid phase, at a temperature between 120 and 240 degrees C, in the presence of an effective amount of nickel, characterised in that the reaction is carried out under a partial pressure of carbon monoxide which is less than or equal to 150 bars, in the simultaneous presence of at least one alkali metal halide or alkaline earth metal halide, at least one alkyl halide and a solvent chosen from the group comprising tetramethylenesulphone, its derivatives obtained by replacing one or more hydrogen atoms by alkyl radicals containing from 1 to 4 carbon atoms, polyethylene glycol alkyl ethers of the formula R**1 -O-(CH2 -CH2 -O)m -R**2 in which R**1 and R**2 , which are identical or different, represent an alkyl radical containing from 1 to 4 carbon atoms and m is an integer which can vary from 1 to 8 (1 =< m =< 8), and the compounds of the formula see diagramm : EP0018927,P12,F1 in which R**3 , R**4 and R**5 , which are identical or different, represent a linear or branched alkyl radical, a cycloalkyl radical, an aralkyl radical or a monocyclic aryl radical, the said radicals having at most 10 carbon atoms, it being possible for two of the radicals R**3 , R**4 or R**5 together to form a single divalent radical -(CH2 )n -, being an integer between 3 and 12 (3 =< n =< 12), and it also being possible for R**3 to represent hydrogen or a radical see diagramm : EP0018927,P13,F1 in which R**6 and R**7 , which are identical or different, represent an alkyl radical having from 1 to 4 carbon atoms. |
