Titre : Solubilities of pimelic acid in ionic liquids Type de document : texte imprimé Auteurs : Hua Li, Auteur ; Juan Liu, Auteur ; Daokui Tang, Auteur Année de publication : 2011 Article en page(s) : pp. 10370-10372 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Ionic liquid Solubility Résumé : The solubilities of pimelic acid in ionic liquids [EMIM][HSO4], [PMIM]Br, [i-PMIM] [HSO4], [BMIM]Br, and [BMIM] [HSO4] are determined with the suitable experimental methods and apparatus. The experimental data of solubilities are correlated with the Apelblat equation. The solubilities correlated by the model are in good agreement with experimental data.

Titre : Study on separation and purification of genistein in the soybean residue using macroporous resin adsorption Type de document : texte imprimé Auteurs : Hua Li, Auteur ; Juan Liu, Auteur ; Li, Dan, Auteur Année de publication : 2012 Article en page(s) : pp. 44-49 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Adsorption Macroporosity Purification Résumé : Soybean residue is a rich byproduct that is discarded in soybean processing factories. In this research, soybean residue was used to prepare highly valued genistein by separation and purification through the combination ofisoelectric point precipitation, centrifugation, solvent extraction, and macroporous resin adsorption. The purification process had been studied in detail. The results showed that AB-8 resin, feathering high adsorption and desorption recovery, is a suitable resin for purifying genistein, and a optimized process for gradient elution was obtained: the extracts was sequentially eluted with deionized water, 20% ethanol, and 70% ethanol in the first process, and with 40% ethanol and 70% ethanol in the second process; the purity of genistein was about 90% by high-performance liquid chromatography (HPLC) analysis.
