| Abstract: | The solid superbase catalyst 2Na＋O2^-/Al-MCM-41 was prepared using A1-MCM-41 molecular sieve as the carrier and characterized by XRD, FT-IR, BET, SEM, TEM, the base strength, basicity and other testing methods. The results showed that compared with the same kind of solid superbase catalyst,2Na＋O2^-/Al-MCM-41 possessed rich pore structure, ideal base strength and basicity. The catalyst was used in the synthesis of bis-benzalacetone and exhibited good low-temperature catalytic activity and selectivity. |
