Technology Process of Methylium

There total 14 articles about Methylium which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

oxygen (1+) → methyl cation (14531-53-4) + methane cation radical (74-82-8,27680-53-1) + CH3O2(1+) (86475-50-5) + hydroperoxyl radical (7782-44-7)

Guidance literature:

With methane; In gas; byproducts: O2; other Radiation; irradiation of O2(1+) and CH4 (beam-gas mode, light source is the many-line emission spectrum of hydrogen with a monochromator bandwith of about 0.5?, further intermediate H); Kinetics;
