Synthesis, characterization and application of MCM-22 zeolites via a conventional HMI route and temperature-controlled phase transfer hydrothermal synthesis

With less environmental and economical impact, temperature-controlled phase transfer hydrothermal synthesis of MWW zeolites was realized with hexamethyleneimine as a structure-directing agent and aniline as a structure-promoting agent. MCM-22 zeolite, synthesized via temperature-controlled phase transfer hydrothermal synthesis, is nearly identical concerning chemical composition and structure, and possesses nearly identical properties with respect to porosity, Si/Al ratio, thermal behavior and catalytic activity at 200°C, compared with that made from conventional synthesis with hexamethyleneimine as the only template.

INTERMOLECULAR HYDROGEN TRANSFER IN UNSATURATED HYDROCARBONS INDUCED BY DIMERIC TITANOCENE

μ-(η5:η5-Fulvalene)-di-μ-hydrido-bis(η5-cyclopentadienyltitanium) and μ-(η5:η5-fulvalene)-μ-chloro-μ-hydrido-bis(cyclopentadienyltitanium) form a thermally stable complex which catalyzes the intermolecular hydrogen transfer in unsaturated hydrocarbons, in addition to isomerizations and cyclizations.Cyclic hydrocarbons disproportionate under catalysis to saturated and aromatic hydrocarbons, while linear olefins yield predominantly linear alkanes and high molecular weight tar.The catalyst enables the hydrocarbon system to approach the thermodynamicequilibrium through a series of substitution reactions between alkyl- and allyltitanocene-like species and olefins and dienes.The catalytic complex was characterized by UV and ESR spectra.About one half of overall titanium content could be converted to mononuclear η3-allyltitanocene-like species, stable up to 400 deg C.This exceptional thermal stability is ascribed to a firmly bound allyl containing ligand.
