FIELD: petrochemical processes. SUBSTANCE: hydrocarbon mixtures containing at least non-tertiary C<SB>3</SB>-C<SB>6</SB>-alkenes are brought into liquid-phase contact with heterogeneous acid catalyst(s). In the zone where dimers and/or codimers and/or trimers of non-tertiary C<SB>3</SB>-C<SB>6</SB>-alkenes are formed, sulfonate-ionite catalyst is used and temperature 80-135, preferably 90-115 C, is maintained. EFFECT: eliminated corrosive danger, lowered process temperature, and simplified process technology. 7 cl, 4 dwg, 2 tbl, 11 ex
