| | 1,2-Epoxy-4-vinylcyclohexane Usage And Synthesis |
| Chemical Properties | Colorless liquid | | Uses | Vinylcyclohexene monoxide is a chemical intermediate; it
can be copolymerized with other epoxides to yield polyglycols
having unsaturation available for further reaction. | | Definition | ChEBI: 3-Vinyl-7-oxabicyclo[4.1.0]heptane is an oxacycle. | | Synthesis Reference(s) | Tetrahedron Letters, 22, p. 2089, 1981 DOI: 10.1016/S0040-4039(01)93284-8 | | Synthesis | 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. | | Toxics Screening Level | The initial threshold screening level (ITSL) for 1,2-epoxy-4-vinylcyclohexane is 6.0 μg/m3 based on an annual averaging time. | | References | [1] RSC Advances, 2014, vol. 4, # 61, p. 32054 - 32062 [2] Applied Catalysis A: General, 2013, vol. 466, p. 142 - 152 [3] Journal of the American Chemical Society, 2009, vol. 131, # 36, p. 12890 - 12891 [4] Patent: CN108101868, 2018, A.
