Abstract
A process is described for the separation of C.sub.5 hydrocarbons present, in a quantity ranging from 0.2 to 20% by weight, in streams prevalently containing C.sub.4 products used for the production of high-octane hydrocarbon compounds, by the selective dimerization of isobutene, characterized in that the dimerization reaction is carried out in the presence of linear and branched alcohols and alkyl ethers in a quantity which is such as to have a molar ratio alcohols/alkyl ethers/isobutene in the feeding higher than 0.01.
