Preparation of cellulose nanoparticle from cinnamon
The preparation of cellulose nanostructures is considered in this paper. Cellulose nanoparticles(nano cellulose) were extracted from cinnamon for the first time. The chemically-induceddestruction strategy based on controlled strong acid hydrolysis treatment was used for dissolutionof lignin and fragmentation of cellulose to nano sized structure. The products werecharacterized by scanning electr...
متن کاملSubmitted to Cellulose About the Depolymerization of Cellulose Propionate to Segments with low DP
Low molecular weight cellulose propionate (CP) segments were synthesized by HBr hydrolysis under esterification conditions using either a commercial CP with residual hydroxyl groups (DSOH ca. 0.4) or a tripropionate (CTP). The hydrolysis using CTP yielded segments having a minimum DP of as low as 7, whereas the hydrolysis of the commercial CP resulted in segments having a minimum DP of 50. Diff...
متن کاملCellulose-bound peptide arrays: preparation and applications.
The way of the development of the cellulose-bound peptide arrays leads via the synthesis of oligonucleotides on cellulose pieces (Frank et al., 1983) and multiple peptide synthesis on cellulose paper discs in columns (Frank and Döring, 1988). Probably inspired by the addressability of the multipin method (Geysen et al., 1984), Ronald Frank and co-workers developed SPOT synthesis and first prese...
متن کاملAcetylation of Bacterial Cellulose: Preparation of Cellulose Acetate Having a High Degree of Polymerization.
Cellulose triacetate prepared from bacterial cellulose of Acetobacter xylinum subsp. sucrofermentans BPR3001A showed a higher degree of polymerization and higher mechanical strength than that from the cotton linter. The fine fibrils of bacterial cellulose required only a short time for acetylation which preserved the high degree of polymerization.
متن کاملThe preparation of graft copolymers of cellulose and cellulose derivatives using ATRP under homogeneous reaction conditions.
In this comprehensive review, we report on the preparation of graft-copolymers of cellulose and cellulose derivatives using atom transfer radical polymerization (ATRP) under homogeneous conditions. The review is divided into four sections according to the cellulosic material that is graft-copolymerised; (i) cellulose, (ii) ethyl cellulose, (iii) hydroxypropyl cellulose and (iv) other cellulose ...
