ABSTRACT:
A process is described for the production of hydrocarbons with a high octane number starting from hydrocarbon cuts containing isobutene by selective dimerization with acid catalysts characterized in that the dimerization reaction is carried out in the presence of primary alcohols and alkyl others in such a quantity as to have in the feeding a molar ratio primary alcohols+alkyl ethers/isobutene of more than 0.1 and a molar ratio primary alcohols/isobutene of less than 0.2, operating, preferably, at a reaction temperature of between 30 and 120.degree. C., at a pressure of less than 5 MPa and feeding space velocities of less than 30 h.sup.-1.
