摘要

Improvements introduced in the object of the main patent no. 443,185 by: oligomerization and codimerization process of tertiary olefins, characterized in that the tertiary olefins or the fraction containing them are brought into contact, at a temperature of 10-100ºC and 0-10 kg/cm2 of gauge pressure, with a catalyst consisting of a phosphoric acid containing in solution a second acid component in a concentration lower than 50% by weight and preferably lower than 20% by weight, this second component being acid one or more of the compounds belonging to the following groups: a) strong organic acids, b) strong inorganic acids, c) a compound containing some element of the va and vb groups of the periodic system. The catalyst may contain up to a maximum of about 5% water and may be dispersed, if desired, in a liquid phase, the separation of the catalyst from the reaction products being carried out by decantation.
