β-cyclodextrin grafted on lignin (l-β-CD) was prepared by the reaction of β-cyclodextrin (β-CD) and lignin with epichlorohydrin (EPI) as a cross-linking agent. The polymer was characterized by Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), Scanning electron microscopy (SEM), and solid-state nuclear magnetic resonance spectroscopy (CP-MAS-NMR). It was used as an inverse...
The efficient synthesis of natural benzaldehyde from natural cinnamon oil catalyzed by 2-hydroxypropyl-β-cyclodextrin (2-HPβ-CD) in water under rather mild conditions has been developed. Various analysis methods, e.g., DSC, UV–vis, 1 H NMR, ROESY, and fluorescence measurements had been utilized to demonstrate formation of the 1:1 (molar ratio) complexes between 2-HPβ-CD and cinnamaldehyde...
