Title
(DE) DARSTELLUNG VON ZIMTSÄUREESTERN
(EN) PRODUCTION OF CINNAMIC ACID ESTERS
(FR) ESTER D'ACIDE CINNAMIQUE
Abstract
(DE)
Nach einem neuen Verfahren zur Synthese von Zimtsäureestern bzw. substituierten Zimtsäureestern werden durch Kondensation Carbonsäureester mit Benzaldehyd bzw. substituierten Benzaldehyden, in Gegenwart eines Feststoffs mit basischen Eigenschaften umgesetzt.
(EN)
The invention relates to a novel method for synthesizing cinnamic acid esters or substituted cinnamic acid esters according to which carboxylic acid esters are reacted with benzaldehyde or substituted benzaldehydes by condensation, in the presence of a solid substance that has alkaline properties.
(FR)
Selon un nouveau procédé de synthèse d'esters d'acide cinnamique ou d'esters d'acide cinnamique substitués, on fait réagir, par condensation, des esters d'acide carboxylique avec du benzaldéhyde ou des benzaldéhydes substitués, en présence d'une matière solide à propriétés basiques.
