- W2363091144 abstract "A series of Hβ zeolite catalysts[Cat T( T was activation temperature) ]and modified Hβ zeolite catalysts{ CatR 550 [R = H 2 SO 4( a),( NH 4) 2 S 2 O 8( b) and( NH 4) 2 SO 4( c) ]} were prepared. Effects of T and R on catalytic activities of the catalysts were investigated in synthesis of 2-ethylanthraquinone( 1) by one-step Friedel- Crafts acylation reaction from phthalic anhydride( 2) and ethylbenzene( 3). The results showed that the optimum T was 550 ℃ and R was c. Effects of reaction temperature,Cat 550 amount and r[n( 2) ∶ n( 3) ]on Friedel- Crafts acylation reaction were investigated using Cat 550 as the catalyst. The results showed that under the optimum reaction conditions[2 was 40 mmol,n( 2) ∶ n( 3) = 1 ∶ 25,Cat 550 was 2. 0 g,for 5 h at 250 ℃ ],the conversion of 2 was 30. 6%,the selectivity of 1 was 33. 8%,the yield of 1 was 10. 3%. Under the same optimum reaction conditions with Cat c 550 as the catalyst and c( c) was 1. 75 mol·L- 1,the conversion was 39. 0%,the selectivity was 43. 4%,and the yield was 16. 9%." @default.
