| Abstract: | Some inorganic salts, such as Cr 2(SO 4) 3, CdSO 4, FeSO 4, VOSO 4, Ce(SO 4) 2, MnSO 4, SnCl 4 and HgSO 4, were used to selectively oxidize methane to monomethyl sulfate in concentrated sulfuric acid. MnSO 4, SnCl 4 and HgSO 4 are active for oxidation of methane. Among them, the best result was given by HgSO 4/H 2SO 4 system, i.e. , conversion 37 3%, selectivity 80 9%, and yield 30 2%, respectively. Based upon those data, the influence of other factors were investigated. An electrophilic displacement reaction mechanism was suggested. |
