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
Supplied in a Sure/Pac™ cylinder and has a brass needle valve with a male 1/4" NPTF outlet thread installed. Before using the cylinder, ensure that the valve is closed, then remove the galvanized steel hex cap that seals the outlet valve.
