Functionalization of Cellulose: Synthesis of Water-soluble Cationic Cellulose Derivatives

One of the trends of modern cellulose chemistry is the functionalization of known cellulose derivatives in order to expand their application area. In this work, water-soluble cationic cellulose derivatives containing up to 4% coupled nitrogen were obtained by the amination of hydroxyethylcellulose (HEC) with two different etherification agents, diethylepoxypropylamine (DEEPA) and (2-chlorethyl)...

Synthesis and Antimicrobial Activity of Nitrobenzyl-oxy-phenol Derivatives.

Two hydroquinone derivatives were prepared and their antimicrobial activity evaluated. Their minimum inhibitory concentrations (MICs) were determined using a broth dilution method. Gentamycin and ciprofloxacin were used as reference antibiotics. The antimicrobial activity of 4-(benzyloxy)phenol (monobenzone) was also evaluated based on its structural similarity to the new compounds; activity wa...

Size Exclusion Chromatography of Cellulose and Cellulose Derivatives

Approximately 2 X 10 ton biomass is produced on land and in water annually (l). Cellulose is the principal structural material in the cell wall of all plants (2). In addition, cellulose can be found in algae, bacteria, and animals (tunicates). Assuming that the average source contains 50% cellulose (Table 1) (35), then approximately 1 X 10 ton cellulose is formed each year. This makes cellulose...

Regular linking of cellulose nanocrystals via click chemistry: synthesis and formation of cellulose nanoplatelet gels.

Over a number of years work in our laboratory has been developing new chemistry for the use of cellulose nanocrystals (CNCs) as scaffolds for the creation of nanomaterials with novel, stimuli responsive characteristics. Our work takes advantage of the rigid nature of CNCs, the unique nanopattern etched on their surface in the form of regularly spaced primary OH groups, and the fact that these m...
