Conversion of agricultural residues to carboxymethylcellulose and carboxymethylcellulose acetate

Industrial Crops and Products, 2014
Abstract In view of continuing interest in the utilization of agricultural by-products, we have converted cellulose, wheat straw, barley straw, and rice hull into carboxymethylcellulose (CMC), using both conventional heat and microwave-assisted synthesis. The application of microwave technology has enabled an improved synthesis of CMC to be conducted,

Determination of Sodium Carboxymethylcellulose*

Journal of the American Pharmaceutical Association (Scientific ed.), 1955
Abstract A method for the determination of sodium carboxymethylcellulose in antibiotic preparations. The copper salt of carboxymethylcellulose is precipitated and analyzed for carboxymethylcellulose colorimetrically using 2,7‐naphthalenediol. Possible use of this method in quantitative determination of carboxymethylcellulose is suggested.

Nitration of carboxymethylcellulose

Chemistry of Natural Compounds, 1994
The influence of the conditions of nitration and the structure of the initial carboxymethylcellulose on the depth of conversion and the molecular characteristics of the nitroesters obtained has been investigated. The products obtained after optimization of the hydrophilic-hydrophobic balance with the aim of imparting solubility to them possess a ...

Carboxymethylcellulose as a colloid laxative

The American Journal of Digestive Diseases, 1949
A new cellulose gum, sodium carboxymethylcellulose, is described which can be used advantageously in the successful treatment of a majority of chronic constipation cases. Over 250 patients, with various degrees of constipation, picked at random from a general practice, were all markedly benefited by the use of small amounts of sodium ...

USE OF CARBOXYMETHYLCELLULOSE IN LOTIONS

Archives of Dermatology, 1949
Jansen1first developed carboxymethylcellulose in Germany in 1918 as a substitute for gelatin, glue, agar-agar, tragacanth and similar substances. Carboxymethylcellulose is used chiefly in industry in the form of its sodium salt. Sodium carboxymethylcellulose is indicated whenever hydrophilic colloids having suspending, stabilizing, film-forming and ...

Preparation of amidated derivatives of carboxymethylcellulose

International Journal of Biological Macromolecules, 2015
Carboxymethylcellulose (CMC) was selected as substrate for amidation based on previous results described for monocarboxy cellulose (MCC) with the aim to prepare highly substituted products. In comparison with MCC containing uronic carboxyl groups at C-6 position, O-carboxymethyl groups in CMC should be more accessible for reagents because they are more

Examination of Small Intestine with Carboxymethylcellulose

Radiology, 1953
Most of us have experienced difficulty at times in deciding whether a small intestine is normal or abnormal by roentgen examination, and further, if abnormal, what name to give to the condition. Different workers use different procedures, administer the barium in different mixtures, and use different terms to describe the resulting radiographic ...

Assemblies of Concanavalin A onto Carboxymethylcellulose

Journal of Nanoscience and Nanotechnology, 2005
The immobilization of Concanavalin A, (Con A), onto flat surfaces formed by ultrathin films of carboxymethylcellulose, CMC, silicon wafers or spin-coated poly(methyl methacrylate), (PMMA), was studied by ellipsometry, contact angle measurements and atomic force microscopy (AFM). The formation of Con A monolayer was only observed onto CMC films.
