摘要
环己烯催化水合生成环己醇是制备己二酸的一种很有前途的方法,以水玻璃为硅源,制备了HZSM-5。采用XRD、NH3-TPD和SEM等技术对制备的HZSM-5催化剂进行了表征。研究发现,制备的HZSM-5催化剂在选择性和活性方面表现良好。环己烯的转化率达到12. 38%,环己醇的选择性达到99%。
The catalytic hydration of cyclohexene to cyclohexanol appears to be a promising alternative in the production of adipic acid. In this paper,the HZSM-5 was successfully synthesized using water glass as silicon source. Prepared HZSM-5 catalysts were characterized using several techniques like X-ray diffraction( XRD),ammonia temperature-programmed desorption( NH3-TPD) and Scanning electron microscopy( SEM). Prepared HZSM-5 catalyst was found to offer the best performance regarding selectivity and activity. The conversion of cyclohexene reached to 12. 38% and the selectivity of cyclohexanol was 99%.
