Kinetics of Catechin-acetaldehyde Condensation Reaction

doi:10.7506/spkx1002-6630-201313002

Abstract

Abstract:

The kinetics of (+)-catechin-acetaldehyde condensation reaction in a wine simulation model was invesitgated by
RP-HPLC-ELSD analysis in this study. The results demonstrated that the reaction followed a first-order kinetic law under the
experimental conditions. Temperature had a significant influence on the reaction rate. The relationship between temperature and
reaction rate obeyed the Arrhenius equation and the activation energy of the condensation reaction was 36.16 kJ/mol.

Key words: (+)-catechin, acetaldehyde, condensation reaction, kinetics

CLC Number:

TS261.4
