Abstract
A process for synthesising t-butyl alkyl ethers is combined with a process for isomerising butene-1 and/or butene-2 in order to increase the ether yield. A C4 hydrocarbon feedstock (1) containing isobutene but free of butadiene is reacted (4) with an alkanol (6) and the ether product (5) is separated from residual hydrocarbons (7), (8); the latter are fractionated to separate saturated hydrocarbons (10), (14), from the butene-1 (12) and the butene-2 (15); the butene-1 and/or butene-2 are isomerised (16) to a product (2) containing isobutene which is recycled to reactor (4). <IMAGE>
