WebRemoval of methyl tert-butyl ether (MTBE) with Nafion WebT-butyl alcohol is a tertiary alcohol, and it goes under an SN1 reaction. The solvent in the action breaks the OH bond to form a tertiary carbocation, and then it forms a bond between the halide ion and t-butyl cation. In this reaction, when t-butyl alcohol is dissolved in the solvent, it will ionize and form a solid by a precipitation reaction. fringe camps https://iccsadg.com
