METHOD OF PREPARING LINEAR INTERNAL OLEFINS OF TRANS STRUCTURE WHICH COMPRISES CONTACTING A LINEAR ALPHA OLEFIN OF THE C6-C24 RANGE AT A TEMPERATURE IN THE RANGE OF 050*C. WITH A CATALYST SYSTEM COMPRISING TICL4 AND AN ALUMINUM ALKYL COMPOUND SELECTED FROM THE GROUP CONSISTING OF ALR3, ALR2CL, ALR1,5CL1,5 AND ALRCL2 WHEREIN THE PROPORTIONS OF TICL4 AND ALUMINUM ALKYL COMPOUND ARE SUCH THAT THE R:TI MOLAR RATIO IS IN THE RANGE OF 0,55.0, WHEREBY CONVERSION OF SAID ALPHA OLEFIN TO HIGHER BOILING COMPOUNDS OCCURS, DISTILLING THE REACTION PRODUCT TO OBTAIN A DIMER FRACTION COMPRISING A MAJOR AMOUNT OF UNBRANCHED TRANS OLEFIN DIMER AND A MINOR BUT SUBSTANTIAL AMOUNT OF VINYLIDENE-TYPE DIMER, AND SELECTIVELY SEPARATING FROM SAID DIMER FRACTION THE UNBRANCHED TRANS OLEFIN DIMER IN A PRODUCT CONCENTRATION OF AT LEAST 95%.
