Embodiment 1
[0019] The present invention is a kind of synthetic method that can realize the catalyst of organic matter catalytic oxidation reaction in water phase, adopts following method to synthesize:
[0020] Put 2.7 mmol of K 8 [SiW 10 O 36 ]·12H 2 O was rapidly dissolved in 2.8 mL of 1 M HCl, followed by the addition of 1.1 mL of 0.5 M NaVO 3 Aqueous solution, the mixture was stirred for 5 minutes to obtain a clear filtrate by suction filtration, i.e., silicotungsten alum-type polyoxometalates ([γ-1,2-H 2 SiV 2 W 10 O 40 ] 4- ) aqueous solution. 10.8 mmol of 3-(N,N-dimethylhexadecylammonium)-propanesulfonate was added to the filtrate, then 10 mL of absolute ethanol was added, and after stirring for half an hour, a yellow solid was obtained by suction filtration. The catalyst was washed three times with water and ethanol, and air-dried to obtain the catalyst.
[0021] A stable emulsion was formed with 5 μmol of catalyst, 2 mmol of thioanisole, 6 mmol of 30% hydrogen peroxide i...
