Synthesis, structure, and optical activity of HPM-1, a pure silica chiral zeolite
2-Ethyl-1, 3, 4-trimethylimidazolium is a poor organic structure-directing agent in the
synthesis of pure silica zeolites using fluoride as a mineralizer at 150° C. Under these
conditions only ill-crystallized solids are obtained after long hydrothermal treatments
(several weeks). It disappoints despite its relatively large size, conformational rigidity, and
intermediate hydrophilic/hydrophobic character, attributes which would qualify it as a
promising structure-directing agent, according to prior investigations. By raising the …
