Tsao George T, Chou Terry Yu Chia: Procede de recuperation et dutilisation de la cellulose a laide dacide sulfurique. Purdue Research Foundation, October 5, 1979: FR2419351-A1 (3 worldwide citation)

On hydrolyse des matières premières cellulosiques à l'aide d'un acide sulfurique dilué pour éliminer l'hémicellulose, après quoi on sépare le résidu solide et on lui ajoute de l'acide sulfurique concentré pour dissoudre la cellulose contenue dans le résidu solide. Après mélange du résidu avec l'acid ...

Purdue Research Foundation, Purdue Research Foundation, SMART & BIGGAR, May 18, 1995: CA2176038 (1 worldwide citation)

Described are recombinant yeasts containing genes encoding xylose reductase, xyl itol dehydrogenase and xylulokinase, and DNA molecules, vectors and methods useful for producing such yeasts. The recombinant yeasts effectively ferment xylose to ethanol, and preferred yeasts are capable of simultaneou ...

Tsao George T, Ladisch Michael R, Bose Arindam: Acid hydrolysis of cellulose to yield glucose. Purdue Research Foundation, October 5, 1979: FR2419324-A1

On récupère la cellulose de matières cellulosiques, de préférence en faisant subir un traitement préalable aux matières cellulosiques en les dissolvant dans du > ou un solvant composé d'un métal chélateur et d'un agent gonflant caustique, puis en en faisant précipiter la cellulose. On réalise l'hydr ...

Tsao George T, Ladisch Michael R, Dale Bruce E: Solvant non toxique de la cellulose, et son procede de preparation et dutilisation. Purdue Research Foundation, October 5, 1979: FR2419350-A1

Le solvant comporte un agent chélateur métallique et un agent gonflant caustique, le solvant étant préparé sous forme aqueuse ou sous forme solide. On met le solvant en contact avec des matières cellulosiques pour en faire précipiter la cellulose. On peut alors hydrolyser la cellulose récupérée à l' ...

Tsao George T, Ladisch Michael R, Ladisch Christine M, Hsu Teh An: Process for treating cellulosic materials and obtaining glucose therefrom. Purdue Research Foundation, November 16, 1979: FR2423580-A1

A process for treating cellulosic materials and obtaining glucose therefrom comprises treating the cellulosic materials to remove hemicellulose, then dissolving the cellulosic materials in solvent, after which lignin is removed and the cellulose is then precipitated from the remaining solution. The ...

Tsao George T, Chen Li F: Cellulose poreux en billes, Porous cellulose beads. Purdue Research Foundation, April 22, 1980: CA1076047

ABSTRACTPorous cellulose beads are prepared by distri-buting droplets of a solvent mixture containing a cellulosederivative into a precipitating solution to form porousbeads which are then washed and hydrolyzed to form porous cel-lulose beads. The porous cellulose beads, which may becross-linked, if ...
