Procedure

The bottom product (IV) from the column K1 comprised predominantly unreacted MTBE (about 23% by mass) and methanol (about 75% by mass). In addition, unreacted 2-methoxybutane, tert-butanol, water and diisobutene formed by reaction and also diisobutene originating from the feed MTBE, inter alia, were present. This stream was fed to the column K2.
