Heteropoly blue Q7PMo12O42(Q=C5H5NC16H33) has been designed and synthesized as reaction-controlled phase-transfer catalyst for catalytic epoxidation of cyclohexene and catalytic oxidation of benzalcohol with H2O2 as the oxidant. The efficiency of H2O2 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 H2O.

Key words: reaction-controlled phase-transfer catalyst, benzalcohol, cyclohexene, heteropoly blue
