Cyclohexane with iodine
WebOct 25, 2011 · In this second series of posts we go beyond these to introduce a few of the less common (but still important) reactions you learn in organic chemistry 1. We talked about rearrangements last time: today let’s talk about free-radical substitution, and leave cleavage (oxidative cleavage) for last. As I’ve said with everything in this series ... WebOct 1, 2024 · The adsorption performance to iodine was investigated by the capture of both volatile iodine and iodine solution in cyclohexane. P-COF exhibited rapid and excellent adsorptive performance of iodine. The adsorption capacity of volatile iodine reached 6.19 g g−1. After five cycles, the P-COF still retained above 70% of its initial uptake capacity.
