Abstract
An important cellulose mixed ester, cellulose acetate butyrate (CAB), was successfully prepared in tetrabutylammonium acetate (TBAA)/dimethyl sulfoxide (DMSO) system. The structure of the cellulose derivative was characterized with a Fourier Transform IR spectrometer and analyzed using 13C cross‐polarization magic angle spinning nuclear magnetic resonance. The degree of substitution (DS) of the samples prepared was calculated according to 1H‐NMR analysis. And the solubility of CAB was investigated in a wide range of traditional organic solvents such as 2‐methyl‐ethyl ketone, dichloromethane and ethyl acetate. The thermal properties of the product were analyzed by TGA analysis. The surface morphology of the esters was characterized with a field emission‐scanning electron microscopy (FE‐SEM). The relationship among surface morphology, solubility, and DS of the cellulose mixed ester was discussed. Moreover, TBAA and DMSO were recovered by vacuum distillation, which was characterized by Fourier transform infrared spectroscopy.
