METHOD OF PREPARING DI-AND TRIMERS OF C-C ALKENES AND/OR MIXTURES THEREOF WITH ALCOHOLS Russian patent published in 2000 - IPC

FIELD: petrochemistry. SUBSTANCE: alkenes or alkene-containing mixtures are subjected to liquid phase contacting with sulfoionite catalyst in H₊ from at elevated temperature followed by distillation of at least unreacted C₃-C₄ hydrocarbons and optionally the resulting alcohol(s). Water content in sulfocationite catalyst is maintained from 2 to 35% by weight of dry catalyst. Water is fed in molar ratio to hydrocarbons from 0.002 to 0.03:1, preferably from 0.01: 1 to 0.1:1. EFFECT: more efficient process and lower desactivation of the catalyst. 7 cl, 8 ex, 3 dwg, 1 tbl
