文摘
- •
Aromatics are precursors to olefins in the induction period.
- •
Bulky methylbenzenes show higher reactivity than light counterparts.
- •
Light methylbenzenes such as xylene and trimethylbenzene favor ethene.
- •
Pentamethylbenzene and tetramethylbenzene favor propene.
- •
Ethene and propene are linked to methylbenzenes by the paring route.
