Selective hydrogenation of maleic anhydride to tetrahydrofuran over Cu−Zn−M (M = Al, Ti, Zr) catalysts using ethanol as a solvent / Dongzhi Zhang in Industrial & engineering chemistry research, Vol. 48 N° 24 (Décembre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 24 (Décembre 2009) . - pp. 11220–11224 Titre : Selective hydrogenation of maleic anhydride to tetrahydrofuran over Cu−Zn−M (M = Al, Ti, Zr) catalysts using ethanol as a solvent Type de document : texte imprimé Auteurs : Dongzhi Zhang, Auteur ; Hengbo Yin, Auteur ; Jinjuan Xue, Auteur Année de publication : 2010 Article en page(s) : pp. 11220–11224 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Selective--Hydrogenation--Maleic--Anhydride--Tetrahydrofuran--Cu−Zn−M  (M  =  Al,  Ti,  Zr)--Catalysts--Using  Ethanol--Solvent Résumé : A series of Cu−Zn−M (M = Al, Ti, Zr) catalysts were prepared by coprecipitation method and characterized by X-ray diffraction, X-ray photoelectron spectroscopy, and N2 adsorption. The catalytic activity of the Cu−Zn−M catalyst in maleic anhydride hydrogenation using ethanol as a solvent was studied at 220−280 °C and 1 MPa. The presence of MxOy in Cu−Zn−M (M = Al, Ti, Zr) catalysts favored the deep hydrogenation of maleic anhydride to tetrahydrofuran. The catalysts using TiO2 as a support showed the highest selectivity of tetrahydrofuran. The catalytic activity of the catalysts in the hydrogenation of maleic anhydride to tetrahydrofuran followed a sequence of Cu−Zn−Ti > Cu−Zn−Zr ≈ Cu−Zn−Al.

Selective synthesis of potassium titanate whiskers starting from metatitanic acid and potassium carbonate / Jiancui Cao in Industrial & engineering chemistry research, Vol. 49 N° 19 (Octobre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 19 (Octobre 2010) . - pp. 9128–9134 Titre : Selective synthesis of potassium titanate whiskers starting from metatitanic acid and potassium carbonate Type de document : texte imprimé Auteurs : Jiancui Cao, Auteur ; Aili Wang, Auteur ; Hengbo Yin, Auteur Année de publication : 2010 Article en page(s) : pp. 9128–9134 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Potassium  titanate  whiskers Résumé : Selective synthesis of potassium titanate whiskers starting from metatitanic acid and potassium carbonate was successfully carried out by a facile calcination method. The mole ratio of potassium carbonate to metatitanic acid and the calcination temperature and time were crucial to the formation of different-structured potassium titanate whiskers. Well-crystallized potassium tetratitanate whiskers were prepared at a calcination temperature of 1000 °C when the mole ratio of potassium carbonate to metatitanic acid was 1:2.5. Potassium hexatitanate whiskers were dominantly formed at 1150 °C when the mole ratios of potassium carbonate to metatitanic acid were in a range of 1:3.5−1:4.5. Well-crystallized potassium octatitanate whiskers were prepared when potassium tetratitanate whiskers were boiled in water and then dried at a high temperature of 400 °C. The growth directions of all the potassium titanate whiskers are along their [010] crystal directions.
