ABSTRACT:
A process is described for the joint production of ethers and hydrocarbons with a high octane number starting from C.sub.4 hydrocarbon cuts containing isobutene, by oligomerization with acid catalysts, in the presence of primary alcohols selected from methanol or ethanol in such a quantity as to have a molar ratio primary alcohols/isobutene in the feeding of between 0.2 and 0.7, preferably operating at a reaction temperature of between 30.degree. and 100.degree. C. and at feeding space velocities of less than 20 h.sup.-1.
