Chlorotriphenylsilane 96%

Application
Chloromethane also called methyl chloride Refrigerant-40 R-40 or HCC 40 is a chemical compound of the group of organic compounds called haloalkanes. It was once widely used as a refrigerant. It is a colorless extremely flammable gas with a mildly sweet odor which is however detected at possibly toxic levels. Due to concerns about its toxicity it is no longer present in consumer products

Purpose
For R&D use onlynot for drug household or other uses.

General Description
Conversion of chloromethane over metal-exchanged zeolite ZSM-5 catalyst with alkaline earth metals and some transition metals has been studied[2]. 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 byin situFTIR spectroscopy and catalytic testing
