However, its rigid crystalline structure, poor solubility in organic solvents and poor processability have limited its use. To broadening its range of applications, a growth research effort has been devoted to explore ways of modifying Chitosan. Here it has been reported on the synthesis of new ...
Chitosan is neither soluble in water nor in organic solvents. However, after protonation of amine functionalities from glucosamine units by acid, the electrostatic repulsions between NH3+ groups lead to the destruction of interchain attractive interactions, such as hydrogen bonds and hydrophobic interactio...
because of better solubility inorganic solvents[5]. Furthermore, the presence of primary –NH2groups in chitosan helps to be functional in biomedical applications compared to other natural polysaccharides. The physicochemical properties of chitosan and chitosan-basednanomaterialsmainly rely on theirmolecular...
Chitosan is a product of the deacetylation of chitin, which is widely found in nature. Chitosan is insoluble in water and most organic solvents, which seri... 岳超 柳 - 《Hans Journal of Biomedicine》 被引量: 0发表: 2019年 Irradiated chitosan nanoparticle as a water-based antioxidant and re...
N,O-hexanoyl chitosan (HC) displayed unique properties of excellent processibility, solubility in common organic solvents and cationic characteristics, thereby might find versatile applicaions for biomedical engineering. In this study, the biocompatibility of HC was evaluated. The effect of HC on derm...

The solubility of the chitosan depends on the medium being used to dissolve it; in acid mixtures with water, it is soluble, but it is insoluble in common organic solvents [51,52]. The reason for its solubility can be explained due to the presence of amino groups that transforms chitosan ...
Scheme 3. One-pot synthesis of γ-azido-α-diazo-β-keto ester 2q in aqueous medium. 2.4. Recycling of the catalyst Due to its limited solubility in organic nonpolar solvents, chitosan can be readily recovered from the reaction medium for potential reuse in subsequent cycles, which is an im...
