The phrase "aromatic cycle" is correct and usable in written English.
It can be used in contexts related to chemistry, particularly when discussing compounds that contain aromatic rings and their reactions or properties.
Example: "The study focused on the aromatic cycle of benzene derivatives and their reactivity under various conditions."
Alternatives: "aromatic ring" or "aromatic pathway".
The amino group in the aromatic cycle of benzene sulfonamide increased interaction between additives and the cathode.
7, 14, 22, 24– 27 For MTO conversions using H-ZSM-5 catalysts, it has been shown that the formation of ethene from methanol progresses solely through an aromatic hydrocarbon pool mechanism which relies on poly-substituted methylbenzene molecules, while propene formation is linked to both the aromatic cycle and an olefin based cycle, as depicted in Figure 1.
There is a gradual increase in the orientation function of the aromatic cycles, 〈P2(cos θ)〉c, with λ, but the values are higher than those reported in the literature, due to the absence of relaxation in the simulation.
Quenching is related to a variety of processes including excited-state reactions, energy transfer, dimerization between aromatic cycles of molecules and collisional quenching [ 34, 36, 83].
More specifically, the change in selectivity arises from the ability of a zeolitic framework to stabilize carbenium ions, which are the intermediate species in the bimolecular cracking mechanism and the aromatic-based cycle in MTH.
Therefore, it is suggested that modification by phosphorus of H-ZSM-5 inhibits the bimolecular cracking mechanism in alkane cracking and the aromatic-based cycle in methanol-to-hydrocarbon reactions.
For H-ZSM-5, an alkene based and an aromatics based catalytic cycle for product formation are distinguishable.
In contrast, the mesopores in between were the secondary pores of zeolites and are used for cracking cycloparaffins and side chains of aromatics into light cycle oil (LCO).
In contrast, the mesopores (2 50 nm), which are composed of secondary pores of zeolites and amorphous matrix, can be used for the cracking cycloparaffins and side-chain aromatics into light cycle oil (LCO).
High level combined quantum mechanics/molecular mechanics (QM/MM) methods are used to calculate the potential energy and dipole moment surfaces for the motion of the labile proton in an intermediate in the catalytic cycle of aromatic amine dehydrogenase (AADH).
By conducting co-reaction experiments (MeOH + propene or MeOH + p-xylene) over H-ZSM-5 we were able to evaluate the relative rates of ethene and propene formation from both the alkene and the aromatics based catalytic cycles.
