Embodiment 1 2
[0029] After adding 0.1mmol styrene to 2.5ml deionized water, sonicate for 10s, add 10mg9wt% palladium-carbon nitride catalyst and sonicate for 1min, add 3 times the equivalent of formic acid to start the reaction, and use gas chromatography (FID detector) analysis results as shown in the figure after the reaction As shown in l, the substrate conversion rate is greater than 99%, and the selectivity of ethylbenzene is greater than 99%.
Embodiment 2
[0031] After adding 0.1mmol styrene to 2.5ml deionized water, sonicate for 10s, add 10 mg9wt% palladium-carbon nitride catalyst and sonicate for 1min, under the protection of nitrogen, add 3 times the equivalent of formic acid to start the reaction, and use gas chromatography (FID Detector) analysis result obtains substrate conversion ratio greater than 99%, and ethylbenzene selectivity is greater than 99%.
Embodiment 3
[0033] Add 0.1mmol styrene to 2.5ml ethyl acetate and acetonitrile respectively, then sonicate for 10s, add 10mg9wt% palladium-carbon nitride catalyst and sonicate for 1min, add 3 times the equivalent of formic acid to start the reaction, and analyze it with gas chromatography (FID detector) after the reaction As a result, the conversion rate of the substrate is greater than 99%, and the selectivity of ethylbenzene is greater than 99%.
