Reactions of Methyl Iodide and Halopropanes with Na⁰ Treated and Untreated NaX and NaY Zeolites

Abstract

Products formed from reactions of methyl iodide, 1-chloropropane, 1-iodopropane and 1bromopropane with Na 0 treated and untreated NaX and NaY zeolites were studied using solidstate 13 C NMR and IR spectroscopy. At room temperature, methyl iodide dissociates to form framework methoxy in untreated NaX zeolite with no reaction observed in untreated NaY. Upon Na 0 treatment, both NaX and NaY reacts with methyl iodide to form framework methoxy, methane and ethane. 1-iodopropane undergoes dehalogenation to form framework propoxy while 1-chloropropane and 1-bromopropane undergoes dehalogenation and dehydrohalogenation to form framework propoxy and propene respectively.Mater.
