In a method for selectively obtaining α-alkyl cinamaldehydes, more particularly jasminaldehyde, by direct reaction of n-alkyl aldehydes and benzaldehyde or an aromatic ring-substituted benzaldehyde, heterogeneous acid catalysts are used: aluminum phosphates (AlPO), silicoaluminum phosphates (SAPO) and silicoaluminates (SAM) or basic catalysts corresponding to nitrides of said acid catalysts: aluminum phosphate oxynitrides (AlPON), silicoaluminum phosphate oxynitrides (SAPON) y silicoaluminate oxynitrides (SAMON). |
