文摘

Methyl- and dimethyl-ephedrine derivatives drive the synthesis of AFI framework. Resistance of dimethyl-ephedrinium to hydrothermal treatment is lower. Supramolecular aggregation is reduced upon addition of methyl groups on ephedrine. Ephedrine dimers are more stable because of H-bond inter-dimer interactions.
