Byproducts And Reactions of Cyclohexene

 

Cyclohexene CAS 110-83-8 is vital to the chemical industry because it has an essential role as an intermediary material in producing adipic acid, nylon-6, nylon-66, and other fine chemicals. The partial benzene hydrogenation reaction that produces cyclohexene has recently received much attention due to its atom economy over the dehydration of cyclohexanol. 

Ruthenium has been discovered to be the most effective catalyst in this process. To improve cyclohexene selectivity, a second element, such as zinc, cobalt, cerium, barium, iron, lanthanum, boron, or copper, must be added to the Ru-based catalyst. 

Among these additives, Zn is the most widely used, and the Ru-Zn catalyst is used in the only industrialized production process for cyclohexene via partial hydrogenation of benzene, invented by Asahi Chemical Industry Co. Though Zn is often used in Ru catalyzed partial hydrogenation of benzene, its effect is not entirely understood. A recent study found that when using Ru-Zn and SiO2 catalysts for partial hydrogenation of benzene, the catalyst's activity declined as the Zn content increased, whereas cyclohexene selectivity increased. 

Hydrogen temperature-programmed desorption studies demonstrated that under the effect of Zn, two types of hydrogen, both weakly and strongly bound, were generated on the surface of the Ru-Zn/SiO2 catalyst. A separate study looked at the influence of Zn on a Ru-based catalyst during the partial hydrogenation of benzene from the standpoint of adsorption. DFT calculations indicated that Zn inhibited the chemisorption of benzene and cyclohexene on the catalyst, particularly for the latter. 

Some Byproducts Of Cyclohexene

Cyclohexene oxidation products are basically used as intermediates in the production of valuable compounds such as cyclohexanol, cyclohexenone, cyclohexadiene, and others. In a batch reactor, the uncatalyzed oxidation of cyclohexene with molecular oxygen was investigated. The products, cyclohexene hydroperoxide, cyclohexenol, cyclohexenone, and cyclohexene oxide, were produced at temperatures ranging from 343 to 393 K, and kinetic parameters such as temperature, agitation speed, and wall material were measured and monitored.

What's the Distinction Between Cyclohexane and Cyclohexene?

Cycloalkanes such as cyclohexane are chemical molecules with single covalent bonds between carbon atoms in a ring configuration. On the other hand, cycloalkenes are organic compounds with single bonds as well as one or more double bonds between carbon atoms in a ring structure. A good example of cycloalkenes is cyclohexene.

The primary distinction between cyclohexane and cyclohexene is that cyclohexane is a saturated hydrocarbon while cyclohexene is an unsaturated hydrocarbon. Another significant difference is that the former is more stable and hence less reactive. In contrast, the latter is more unstable and can undergo reactions due to a double bond in the ring structure.
