- 摘要：
- The dehydration of 2-(4′-ethylbenzoyl) benzoic acid (BE acid) into 2-ethylanthraquinone (2-EAQ) was investigated over different solid acid catalyst .Of H-Beta、HM、HY、HZSM-5、HMCM-22, H-Beta expressed the best catalytic activity ,the conversion of BE acid can reach 99.5%, and the selectivity to 2-EAQ is up to 96.8%. The results show that the H-Beta zeolite can be considered as an efficient catalyst for the substitute of concentrate H2SO4 or oleum catalyst in the dehydration of BE acid for the synthesis of 2-ethylanthraquinone.
