FIELD: industrial organic synthesis.
SUBSTANCE: before olefin-containing raw material is brought into contact with isomerization catalyst, one or several components of the raw material are subjected to preliminary treatment coming into contact with preliminary treatment material containing zeolite with pore size at least 0.35 nm. Initial olefin is, in particular, vinylidene olefin of general formula CH2=C(R1)R2, wherein R1 and R2 independently represent alkyl groups having at least 2 carbon atoms so that molecular structure includes at least one allyl hydrogen atom.
EFFECT: increased selectivity.
