Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 24 (Décembre 2009) . - pp. 10779–10787 Titre : Design of a reactive distillation column for direct preparation of dichloropropanol from glycerol Type de document : texte imprimé Auteurs : Zheng-Hong Luo, Auteur ; Xiao-Zi You, Auteur ; Jie Zhong, Auteur Année de publication : 2010 Article en page(s) : pp. 10779–10787 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Design--Reactive--Distillation--Column--Direct--Preparation--Dichloropropanol--Glycerol Résumé : In the present study, a reactor design for the direct preparation of dichloropropanol (DCP) from glycerol (GLY) is presented. As an optimum design, a reactive distillation (RD) column in which the second chlorination of GLY occurs during the direct preparation of DCP from GLY has been introduced. Using a simple equilibrium mathematical model of RD, a pilot plant scale column is designed. Furthermore, the whole preparation process of DCP from GLY used the optimum RD column as the central unit is simulated by using an advanced software tool, namely ASPEN PLUS. The pilot plant realization of the whole preparation process is presented and its results are compared with the theoretical prediction. On the basis of the pilot plant data and simulated results, a new technology of DCP production has been designed.

Direct preparation kinetics of 1,3-dichloro-2-propanol from glycerol using acetic acid catalyst / Zheng-Hong Luo in Industrial & engineering chemistry research, Vol. 48 N°1 (Janvier 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N°1 (Janvier 2009) . - P. 446-452 Titre : Direct preparation kinetics of 1,3-dichloro-2-propanol from glycerol using acetic acid catalyst Type de document : texte imprimé Auteurs : Zheng-Hong Luo, Editeur scientifique ; Xiao-Zi You, Editeur scientifique ; Hua-Rong Li, Editeur scientifique Année de publication : 2009 Article en page(s) : P. 446-452 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Dichloropropène  Glycerol  Acetic  Acid  Catalyst  Kinetic  model Résumé : Direct preparation of 1,3-dichloro-2-propanol from glycerol is carried out in a batch reactor using acetic acid catalyst at 363−393 K. The analytical technique, gas chromatography, is employed in order to follow the time evolution of the reagents. The kinetic model of the process is developed. Furthermore, the model parameters of the process are also determined by data fitting. The results show that direct preparation follows the SN2 mechanism. A kinetic model corresponding to the mechanism is proposed in this work. The experimental results show that the kinetic model agrees well with the experiments.
