Web3 mei 2013 · The pseudo-first order reaction rate constant of the cyclopentanone transformation on Ce–Ni–W–B amorphous catalyst was high to 0.31 mL/(g catalyst s). The HDO of cyclopentanone on these Ni–W–B amorphous catalysts proceeded with hydrogenation–dehydration route to produce cyclopentene and cyclopentane. Web(2) measured the heat of hydrogenation (acetic acid solution, 25°C) of 1-methylcyclohexene, methylene- cyclohexane, 1-methylcyclopentene, and methylene- cyclopentane, and found that hydrogenation of the exo double bond is more exothermic in both the five-membered ring (by 3.7 kcal/mol) and six- membered ring (2.1 kcal/mol).
WebThe modeling of the hydrogenation of cyclopentene without catalyst was carried out by progressive approach of the two reactive molecules (H 2 and C 5H8). The approach … WebThe angle strain is minimum in the case of cyclopentane; therefore, it is a less strained molecule and consequently should be a most stable molecule. It is found to be true as cyclopentane undergoes ring opening in drastic conditions. The angle strain increases with the increase in the number of carbon atoms further from cyclohexane onwards.
