| Abstract: | Heteropoly blue Q 7PMo 12O 42 (Q=C 5H 5NC 16H 33) has been designed and synthesized as reaction-controlled phase-transfer catalyst for catalytic epoxidation of cyclohexene and catalytic oxidation of benzalcohol with H 2O 2 as the oxidant. The efficiency of H 2O 2 utilization is 100% and the selectivity to benzaldehyde is 100%. In this system, the catalyst can catalyze reaction as homogeneous catalyst and be easily filtered and reused as heterogeneous catalyst. The co-product is only H 2O. |
