Abstract:

Zeolite H-BEA modified by ethylene diamine tetraacetic acid(EDTA), citric acid, oxalic acid, and tartaric acid were prepared and characterized by XRD and NH3-TPD. The catalytic performance was evaluated in the synthesis of 1-tetralone by intramolecular Friedel-Crafts reaction of 4-phenylbutyric acids. Zeolites H-BEA modified by citric acid showed high catalytic activity. In addition, the reaction conditions such as catalyst amount, reaction temperature and reaction time were examined for the optimal process conditions. Under the optimal reaction conditions, the yield for 1-tetralone was 94.3%.

Key words: henylbutyric acids, tetralones, intramolecular Friedel-Crafts, zeolites H-BEA
