Oxidative decomposition of butyl acetate by micro-nano bubbles at room temperature


Juan Hua, Ya-zhuo Haoa, Jian-jun Weia,b,*, Zhong-ming Guoa, William Baia

 
ABSTRACT:     In this work, the degradation of low-concentration butyl acetate was performed in a micro-nano bubble device via the cavitation effect. The degradation efficiency of this process was investigated for different butyl acetate concentrations. The experimental results showed that with a butyl acetate concentration of 186.5 mg/m3 , the degradation efficiency of butyl acetate was 77.6%. Gas chromatography-mass spectrometry was used to identify the intermediate products generated during different treatment periods under varying initial concentrations. Based on the product analysis, the degradation reaction and pathway were speculated. All the results showed that the major reaction pathway of butyl acetate degradation was the initial production of low-carbon ester, which was then decomposed into butyl alcohol and acetone compounds. This study provides a deeper understanding of the degradation of butyl acetate by micro-nano bubbles and the mechanism of degradation.
