    摘要: Alkyl aromatic compounds are converted to alkyl aromatic aldehydes by a carbonylation reaction. The carbonylation catalyst can be a high boiling point carbonylation catalyst which allows for the separation of the aldehyde product by selective volatilization. Alternatively, the carbonylation catalyst can be selected from perfluoroalkyl sulfonic acids having 2 to 18 carbon atoms, perfluoroether sulfonic acids having 2 to 18 carbon atoms, BF3.(ROH)x wherein R represents CH3 or H and X is a number within the range of from 0.2 to 2, GaBr3, GaCl3, TaF5, NbF5, and NbBr5, with the proviso that when the catalyst is TaF5, NbF5, or NbBr5, then the reaction takes place in the absence of added HF. Preferably, all of the carbonylation reactions take place in the absence of added HF. The alkyl aromatic aldehydes can be oxidized to form an aromatic acid. A mixed xylene feed stock can be converted to a mixture of diemthylbenzaldehydes and then oxidized to form trimellitic acid without the need to separate the xylene or dimethylbenzaldehyde isomers.
