Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 23 (Décembre 2010) . - pp. 12327–12330 Titre : Kinetic analysis of chalcone epoxidation in a biphasic system Type de document : texte imprimé Auteurs : Wai Wing Leung, Auteur ; Ruben M. Savizky, Auteur Année de publication : 2011 Article en page(s) : pp. 12327–12330 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Biphasic  system  Epoxidation  Kinetics Résumé : The kinetics of chalcone epoxidation in a biphasic water/heptane medium system consisting of chalcone as the substrate, hydrogen peroxide as the oxidant, sodium hydroxide as the base, and dodecyltrimethylammonium bromide (DTAB) as the surfactant was investigated. The empirical rate law was established to be described as follows: rate = k[chalcone]0.74[DTAB]0.50[NaOH]0.87[H2O2]1.53. As a preliminary study, the apparent activation energy of the reaction was determined to be 25.9 kJ/mol.
