To prepare biomass-based wood adhesives with good bonding properties and water resistance is still a challenge and meaningful work in the field of the wood industry. Thus in this present study, under low reaction temperature conditions (50掳C), sodium periodate was used as an oxidant to treat ...
Schiff bases have been traditionally prepared by the condensation reaction between a formyl- or carbonyl-containing derivative with primary amine groups in the presence of certain metal ions, such as alkaline earth cations, that act as templating agents. However, tailoring of the Schiff base often ...

[6]. Schiff bases are primarily synthesized by the condensation reaction between primary amines and carbonyl compounds, resulting in the formation of the azomethine group [7], well-known for its capacity to form coordination complexes with practically any metal ion [8]. As a result, numerous ...

The degree of substitution could be estimated via determination the content of free amine groups in chitosan before and after reaction. Table 1 represents the calculated values of DD for chitosan and its two Schiff base derivatives. Moreover, the degree of substitution (DS) was 1.15% for ...

In our work, dextran (Dex) was oxidized into aldehyde-functionalized Dex-CHO before conjugating with doxorubicin (DOX) via efficient Schiff base reaction. The amphiphilic product Dex–DOX aggregated into uniform spherical nanoparticle in aqueous condition. The imine bond in Dex–DOX stayed tough in ...
