General description
Conversion of chloromethane over metal-exchanged zeolite ZSM-5 catalyst with alkaline earth metals and some transition metals has been studied. Chloromethane has been reported as chemical intermediate during the production of gasoline from methane. Catalytic conversion of chloromethane over HSAPO-34 to light olefins has been studied by in situ FTIR spectroscopy and catalytic testing. Chloromethane is a gaseous natural product implicated in methylation processes in PheUinus pomaceus. Chloromethane acts as methyl donor in veratryl alcohol biosynthesis in the lignin-degrading fungi.
Packaging

Utilizing threshold photoelectron-photoion coincidence (TPEPICO) velocity imaging, dissociation of state-selected CH(3)Cl(+) ions was investigated in the excitation energy range of 11.0-18.5 eV. TPEPICO time-of-flight mass spectra and three-dimensional time-sliced velocity images of CH(3)(+) dissociated from CH(3)Cl(+)(A(2)A(1) and B(2)E) ions were
