Abstract
The catalytic process obtains a methyl tertiary butyl ether by feeding methanol over a solid catalyst section in a rectifying column having vertical layers in which a catalyst material is enclosed. At least one of the enclosing walls is impermeable to the catalyst material while being permeable to the methanol. A reactant comprising a mixture of saturated and unsaturated 4 carbon-chain hydrocarbons is fed into the solid catalyst section with methanol to produce a methyl tertiary butyl ether.
