Date: jun-15. 2020.
Doi: 10.1016/j.micromeso.2020.110149.

Abstract:
Ferrierite zeolite was synthesized by a co-structure-directing route using a highly flexible diquaternary ammonium cation (N,N’-bis-triethylpentanediyldiammonium) as a structure directing agent in combination with tetramethylammonium as a small co-structure-directing agent. Strong alterations of the C-13 NMR bands of the bulky organic [read more]

Abstract:
In this work we find a novel conformational sieving effect during the structure-direction of two chiral organic diastereoisomers, (1R,2S)-benzyl-ephedrine and (1S,2S)-benzyl-pseudoephedrine, during the synthesis of zeolitic aluminophosphates. Protonation of each diastereoisomer can take place through two different [read more]
