Triglycidyl isocyanurate [2451-62-9] is a trifunctional monomer containing epoxy groups, and is presently used mainly for cross-linking carboxyl-functional polyester resins in powder coatings. There are three chiral carbon atoms in its molecule, and

A method for the preparation of phase-pure [Al]-BEA and [Al,B]-BEA zeolites based on solid-state recrystallization of synthetic aluminum-containing magadiites is presented. For comparison [B]-BEA was prepared by conventional hydrothermal synthesis. F

Mixtures of NH4Na-Y zeolite and crystalline (NH4)2[SiF6] (applied in molar amounts corresponding to 0.38% of the framework aluminium) were subjected in covered but not hermetically closed dishes to heat treatment at temperatures below the decompositi

Solid-state reactions in ground mixtures of NH4-Y zeolite and crystalline (NH4)2[SiF6] at temperatures below the decomposition point of the complex compound were investigated. The reaction products were characterized by chemical analysis, IR and MAS

Three variants of solid-state ion exchange were studied. Iron exchange was found to proceed in the first case, in theFeCl2+NH4ZSM-5→ FeZSM-5 + NH4Cl↑ process, even at low exchange capacity (Si/Al = 25).The second, Fe2O3 (hematite) + HZ direct rea

High-silica ferrierites (Si/Al=12–35) were prepared by solid-state recrystallization of aluminum-containing kanemite varieties intercalated with piperidine as template. A thermal pretreatment of the kanemite/template mixture at about 360 K prior to

A redox reaction was found to proceed between metallic zinc and zeolitic lattice protons when ground mixtures of zinc dust ( 4 ,Na–Y zeolite, mordenite or varieties of these zeolites prepared by steaming or acid leaching were heated in a vacuum or

In+ cations introduced by reductive solid-state ion exchange into zeolites (Y, ZSM-5, mordenite) and cationic InO+ species created by oxidation of the incorporated univalent cations were found to be detectable and distinguishable by IR spectroscopy u
