Depolymerization of ODPA/ODA polyimide in a fused silica capillary reactor and batch autoclave reactor from 320 to 350 °C in Hot compressed water / Fen Huang in Industrial & engineering chemistry research, Vol. 51 N° 20 (Mai 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 20 (Mai 2012) . - pp. 7001-7006 Titre : Depolymerization of ODPA/ODA polyimide in a fused silica capillary reactor and batch autoclave reactor from 320 to 350 °C in Hot compressed water Type de document : texte imprimé Auteurs : Fen Huang, Auteur ; Yuanyuan Huang, Auteur ; Zhiyan Pan, Auteur Année de publication : 2012 Article en page(s) : pp. 7001-7006 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Autoclave  Batchwise  Reactor Résumé : Depolymerization of polyimide synthesized from 4,4'-oxidiphthalic anhydride and 4,4'-diaminodiphenyl ether monomers (ODPA/ODA PI) in hot compressed water was carried out in a fused silica capillary reactor (FSCR) and batch autoclave reactor system. The phase behavior of ODPA/ODA PI in water during the heating, reaction, and cooling stages of the process in FSCR was observed with an image recording system from under the microscope. The effects of temperature (320―350 °C) and reaction time (30―90 min) on the depolymerization yield and products yields in batch autoclave reactor were investigated at a fixed H2O/PI ratio, and optimal conditions were established. Additionally, an understanding of the reaction pathway of ODPA/ODA PI depolymerization in hot compressed water was developed.

Determination of chlorobenzene solubilities in subcritical water in a fused silica capillary reactor from 173 to 267 °C / Zhiyan Pan in Industrial & engineering chemistry research, Vol. 50 N° 20 (Octobre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 20 (Octobre 2011) . - pp. 11724-11727 Titre : Determination of chlorobenzene solubilities in subcritical water in a fused silica capillary reactor from 173 to 267 °C Type de document : texte imprimé Auteurs : Zhiyan Pan, Auteur ; Zhong Dong, Auteur Année de publication : 2011 Article en page(s) : pp. 11724-11727 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Reactor  Solubility Résumé : The solubility of chlorobenzene was measured in subcritical water using a fused silica capillary reactor (FSCR) combined with a microscope recorder system to capture the images and identify the temperature of total dissolution. The solubility of chlorobenzene was found to vary between 43.5 mg g-1 in water at 173.3 °C and 71.4 mg g-1 in water at 266.9 °C, increasing linearly with temperature. A new approximation model was developed to predict the solubility of chlorobenzene in subcritical water at elevated temperatures. This visualization in the FSCR method does not require sampling and subsequent analysis, and it has a great potential for the solubility determinations of other organic or inorganic materials.
