Production of para-propylbenzaldehyde

The present invention is a process for preparing a 4-alkylbenzaldehyde (para-alkylbenzaldehyde). An alkylbenzene, solvated in a solvent comprising at least one aliphatic solvent having in the range of 3 to 15 carbons, is reacted with carbon monoxide, in the presence of an aluminum halide and a hydro...

Summary:The present invention is a process for preparing a 4-alkylbenzaldehyde (para-alkylbenzaldehyde). An alkylbenzene, solvated in a solvent comprising at least one aliphatic solvent having in the range of 3 to 15 carbons, is reacted with carbon monoxide, in the presence of an aluminum halide and a hydrogen halide acid. Disproportionation is reduced and proportion of para-alkyl-benzaldehyde is increased with respect to other methods.
