Bio-based Films from Linter Cellulose and Its Acetates: Formation and Properties
This paper describes the results obtained on the preparation of films composed of linter cellulose and the corresponding acetates. The acetylation was carried out in the LiCl/DMAc solvent system. Films were prepared from a LiCl/DMAc solution of cellulose acetates (degree of substitution, DS 0.8-2.9) mixed with linter cellulose (5, 10 and 15 wt %). Detailed characterization of the films revealed...
متن کاملSurface properties of water soluble maltodextrin, starch acetates and starch acetates/alkenylsuccinates
Surface and interfacial tensions with hexadecane were measured for water soluble maltodextrin and starch ester solutions in order to determine heir potential as stabilizers or emulsifiers. The surface tension for an acid hydrolysed starch (maltodextrin) initially declined with concentration nd then reached an equilibrium value of 56 mN/m at 20–40 wt.%, suggesting that hydrated starch has this s...

متن کاملSalicylanilide acetates: synthesis and antibacterial evaluation.
A new series of salicylanilide acetates was synthesized and evaluated for their in vitro antifungal and antituberculotic activity. Some of the evaluated compounds possessed comparable or better antifungal activity than a fluconazole standard. All these compounds exhibited very good potential and their in vitro activity against drug resistant and sensitive clinical isolates of Mycobacteria were ...
متن کاملIsolation and Characterization of Acetone-insoluble Substances in Cellulose Acetate Prepared by an Acetic Acid Acetylation Process
Cellulose acetate fibers are commonly made by a dry-spinning process, in which cellulose acetate is firstly dissolved in acetone and then the cellulose acetate acetone solution is extruded through spinneret orifices that have extremely small diameters. Any insoluble substances in acetone solutions could cause disruptions in fiber extrusion, and are not tolerated. In this work, acetone-insoluble...
