FIELD: petrochemical processes. SUBSTANCE: tert-alkene(s) in hydrocarbon mixtures and C1-C2-alcohol(s) are subjected to interaction in presence of acidic heterogeneous catalyst(s) followed by distilling off hydrocarbons in rectification column and withdrawal of desired product as bottom stream at pressure from 1.4 to 20 times, preferably by 2-16 times, exceeding atmospheric pressure. Process involves recycling of stream containing hydrocarbons (predominantly C5-fraction) and alcohol(s) into reaction zone(s). Reaction mixture fed into reaction zone(s) contains at least 20% of C5-hydrocarbons. EFFECT: increased degree of conversion of tert-alkenes. 9 cl, 5 dwg, 6 tbl, 9 ex
