Further Evidence for the Oxidative Methylation of Benzene with Methane over Zeolite Catalysts
We have previously shown in our previous investigations that the presence of oxygen is required for the benzene methylation with methane over zeolite catalysts in a high pressure batch reactor. Thus, a two-step mechanism involving the formation of methanol intermediate by methane partial oxidation followed by benzene methylation with methanol in the second step was postulated. This paper now presents the results of further investigation that provide more evidence that the catalytic benzene methylation with methane does occur and that the reaction is limited by the amount of oxygen. Further support is therefore given to the two-step oxidative reaction mechanism. Suggestions for further work in this area are also given.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
