Jasminaldehyde production without the use of solvents by employing solid-acid catalysts based on a double metal cyanide | Original Article
Solvent-free synthesis of jasminaldehyde via liquid phase condensation of benzaldehyde and 1- heptanal at 433 K is investigated, with a focus on the catalytic activity of Fe-Zn double metal cyanide catalysts. Under ideal reaction circumstances, 1-heptanal is converted to jasminaldehyde with a selectivity of 77. Condensation is facilitated in Fe-Zn double metal cyanide because to the presence of coordinatively unsaturated Zn2+ in the framework of the compound. Selectivity of jasminaldehyde was investigated by varying the complexing and co-complexing agent, catalyst amount, benzaldehyde to 1- heptanal molar ratio, and temperature.
