Cyclohexene transfer hydrogenation

WebSep 11, 2024 · The hydrogenation reaction occurs on the catalyst surface, so the activity of catalyst and selectivity of cyclohexene depends on the mass transfer. The suitable stirring speed could eliminate the diffusion restriction of gas/liquid and liquid/liquid interface. WebIn this experiment, you will perform a transfer hydrogenation on olive oil (an unsaturated fat) using cyclohexene as a hydrogen source to produce shortening (a saturated fat). You will analyze your product by melting point and with a bromine test for unsaturation.
