摘要:

通过恒电位电解甲苯实现了苯甲酸的太阳能热电耦合合成, 考察了电极材料、 反应温度及电解电压对苯甲酸合成的影响. 采用气相色谱、 红外光谱和紫外光谱对电解产物进行分析检测, 证实了太阳能热电氧化甲苯的主要产物为苯甲酸. 实验结果表明, 以石墨作为阳极材料, 反应温度为90 ℃, 电解电压为2.0 V时, 氧化甲苯合成苯甲酸的产率可达51.6%.

Abstract:

Through solar thermal-electrochemical process(STEP) benzoic acid was synthesized by toluene oxidation. The synthesis of benzoic acid was totally driven by solar energy. Direct electro-oxidation behaviors of toluene were studied by cyclic voltammetry(CV) under constant electrolysis potential with three different anodes(platinum, nickel and graphite) in sulfuric acid and sodium dodecyl benzene sulfonate(SDBS). Results showed that the main product of toluene electro-oxidation in the sulfuric acid and surfactant SDBS was benzoic acid, which was detected by gas chromatography(GC), Fourier transform infrared spectroscopy(FTIR) and UV spectrophotometry(UV). The yield of benzoic acid could reach up to 51.6% from toluene by using graphite as anode in the sulfuric acid and surfactant system at 90 ℃ with STEP mode. A new green way of STEP for benzoic acid synthesis was provided.

Key words: Solar energy, Synergistic of thermal and electricity, Electrochemistry, Benzoic acid
