Why does raising the temperature further at higher temperatures favor the disproportionation reaction while being unfavorable for alkylation? What is the reason for this?
Primarily at higher reaction temperatures, as the temperature increases, side reactions such as disproportionation, alkyl transfer, dealkylation, hydrocracking, aromatic hydrogenation, and condensation increase. The molecular structure of C9 is more prone to such side reactions, which therefore hinders alkyl transfer reactions (this is merely my personal opinion)
