METHOD AND (ACID AND BASIC) CATALYSTS FOR OBTAINING ALPHA-ALKYL CINAMALDEHYDES

摘要

Heterogeneous acid catalysts are used in a process for the selective obtainment of alpha -alkylcinnamaldehydes, and more specifically Jasmine aldehyde, by direct reaction between n-alkylaldehydes and benzaldehyde or a benzaldehyde substituted in its aromatic ring: aluminum phosphates (AlPO), silicoaluminophosphates (SAPO), and silicoaluminates (MAS) or basic catalysts corresponding to nitrides of such acid catalysts: oxynitrided aluminum phosphates (AlPON), oxynitrided silicoaluminophosphates (SAPON) and oxynitrided silicoaluminates (SAMON).
