In the TIC chromatogram for the squalene hydrogenation degradation It is possible to calculate the carbon number for these degradation
products (Fig. 3), it is evident that degradation products have been products based on the molecular weight calculated using the chemical
generated by the catalyst, since hydrocarbon peaks C 12 to C 29 can be ionization (CI) method. For details on this analysis, refer to “Analysis
observed in addition to the peak for the main component, squalane of Hydrocarbons Using PCI-GC-MS (from next page, reproduction of
(C 30 ). The intensities of peaks C 12 , C 18 , C 23 , and C 28 , which are shown Application News M270)”. The samples in this investigation were
in red circles, are less than for the other peaks, so it is believed that kindly provided by Professor Tomishige of Hydrocarbon Chemistry,
they are hard to generate in this catalytic reaction process. This means Resources and Environment Labs, Department of Applied Chemistry,
that an intermediate position between branches in the squalane Tohoku University.
molecule is selectively cleaved due to the action of this catalyst to
generate degradation products retaining a branched structure.
