[1] Structurally uniform 1-hexene, 1-octene, and 1-decene oligomers: zirconocene/mao-catalyzed preparation, characterization, and prospects of their use as low-viscosity low-temperature oil base stocks / I. E. Nifant’ev, A. A. Vinogradov, A. A. Vinogradov et al. // Applied Catalysis A: General. — 2018. — Vol. 549. — P. 40–50. An original approach to α-olefin oligomerization as well as novel thermally stable zirconocene catalysts for use in such reactions has been elaborated. The method reported allows the achievement of fractions of lightweight α-olefin oligomers up to 90% yields without considerable formation of byproducts like internal alkenes, alkanes, and higher oligomers. Trimers, tetramers, and pentamers of 1-hexene, 1-octene, and 1-decene were isolated as individual compounds and were hydrogenated. Viscosity characteristics of the isolated saturated and unsaturated hydrocarbons have been studied at various temperatures. The isolated saturated oligomers of 1-octene and 1-decene outperform the traditional electrophilic oligomerization products in terms of viscosity indexes, pour points, and low-temperature viscosity.
