has six isomers: 1-pentene (RON = 90.9 and MON = 77.1 ), cis-2-pentene (unknown octane number), trans-2-pentene (RON = 94 and MON = 80 ), 2-methyl-1-butene (RON = 100.2 and MON = 81.9 [API]), 2- methyl-2-butene (RON = 97.3 and MON = 84.7 ), and 3- methyl-1-butene (unknown octane number) as shown in Figure 4.
The RON 80 E0 1500/6 point had higher amounts of pentene
and heptene, which made the "light alkyl" peak larger.
These peaks are attributed to ethylene and higher oligomers (propylene, butene, pentene
, hexene as well as a series of alkanes), which arise from hydrogen transfer to different positions along the polymer chain .
