METHOD FOR OBTAINING ISOPENTENE OLIGOMERS Russian patent published in 2022 - IPC C07C2/12 C10G50/00 

Abstract RU 2783680 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method for oligomerization of isoamylenes in the presence of a zeolite catalyst. The method is characterized by the fact that granulated NiNa-Ymmm zeolite of a high degree of crystallinity with a hierarchical porous structure is used as a catalyst, the reaction is carried out in the presence of 5-20, wt. %, of catalyst, at 40-110°C, autogenous pressure, for 1-5 hours.

EFFECT: a more efficient method for obtaining isoamylene oligomers, which makes it possible to obtain oligomers with high yield.
