Abstract

Cellulose benzoyl ester (CB) was synthesized from cellulose and benzoyl chloride. Different substitution degree CBs were obtained by controlling the amount of benzoyl chloride, and the resulting CBs have different swelling degree in benzene, cyclohexene and cyclohexane. Hybrid membrane, which was used for the selective hydrogenation, was prepared by supporting Ru nano-clusters (obtained by refluxing reduction of RuCl3 with n-butyl alcohol) into CB. CBs and the hybrid membranes were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and transmission electron microscope (TEM), etc. Research results demonstrated that swelling behavior acts as a crucial factor to the selectivity of cyclohexene. Active evaluation results indicated that the conversion of benzene (highest, 2.8%) increased while the selectivity of cyclohexene (highest, 53.4%) decreased with the increasing of CBs substitution degree.

Key words： Ru nano-cluster; cellulose benzoyl ester; benzene; cyclohexene; swelling
