摘要Ethyl acrylate (EA) is synthesized by ethyl acetate (EtOAc) with formaldehyde (FA) through aldol condensation with fixed-bed reactor, and a series of Ce-P-Cs/gamma-Al2O3 catalyst was developed. The catalysts were characterized with XRD, XPS, SEM-EDS, NH3- and CO2-TPD, BET, and pyridine FTIR. The influence of acidity and basicity on activity was discussed. Catalytic performances were further improved by the addition of small amounts of Ce. Key reaction parameters, such as amount of metal loading, space velocity and reaction temperature, were also optimized. The optimum condition demonstrated a maximum EA yield of 31.38% and 60.03% selectivity toward EA. (C) 2016 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
