Isomerization and disproportionation of 1,3-diethylbenzene is established as a new test reaction for characterizing the effective pore structures of zeolites, complementary to those of meta-xylene and 1,3-diisopropylbenzene. Isomerization of 1,3-diethylbenzene is favored over disproportionation when the pore sizes of zeolites decrease, with 1,4-diethylbenzene being favored over 1,2-diethylbenzene.
