General Steps: 1. Add known amounts of 4-vinyl-1-cyclohexene and TBHP (tert-butyl hydroperoxide) without co-solvent in a 0.25 L capacity jacketed four-neck glass reactor. Set the feed molar ratio (FMR) of olefin to TBHP from 1:1 to 10:1. 2. Start the stirrer and adjust the stirring rate to 300-600 rpm. Heat the reaction mixture through the water bath and reactor jacket, and monitor the temperature using a digital thermocouple to ensure that the temperature of the reaction mixture stabilizes in the range of 323-353 K, with a fluctuation of no more than ±0.5 K. 3. When the reaction mixture reaches a constant temperature, set the FMR to 1:1 to 10:1, without adding co-solvent. 3. When the reaction mixture reached a constant temperature, a known amount of polymer loaded catalyst (0.15-0.6 mol Mo) was added. The time of catalyst addition was recorded as the reaction onset time (t = 0) and an initial sample was taken immediately. 4. Samples were taken at specific time intervals during the reaction and analyzed using Shimadzu GC-2014 gas chromatography (GC). 5. The experimental results showed that the PBI.Mo and Ps.AMP.Mo catalysts exhibited high selectivity in the epoxidation reaction of 4-vinyl-1-cyclohexene, which predominantly yielded 1,2-epoxy-4-vinylcyclohexane, and the GC analyses did not detect terminal or dicyclic oxide products. Detailed results of the batch experiments are discussed in Sect.
