Abstract (en)
[origin: WO2008073096A1] A product comprising a C<SUB>1</SUB>-C<SUB>3</SUB> aliphatic carbbxylic acid or corresponding ester is produced by a process comprising reacting a C<SUB>1</SUB>-C<SUB>3</SUB> aliphatic alcohol or a reactive derivative thereof with carbon monoxide in the presence of a zeolite catalyst having an 8-member ring channel which is interconnected with a channel defined by a ring with greater than or equal to 8 members, the 8-member ring having a window size of at least 2.5 Angstroms x at least 3.6 Angstroms and at least one Brønsted acid site and the zeolite having a silica : X<SUB>2</SUB>O<SUB>3</SUB> ratio of at least 5, wherein X is selected from aluminium, boron, iron, gallium and mixtures thereof with the proviso that the zeolite is not mordenite or ferrierite.
