Shows the SFC-MS CH4 CI spectrum of the 54-carbon ester. The base peak is the ion resulting from hydride abstraction, at m/z 787. The protonated molecule is far less intense than in the spectrum of the lower molecular weight fatty-fatty ester shown in Figure 9. The primary structure present in this peak is the ester of the 36-carbon condensation alcohol with the 18-carbon fatty acid. This information is derived from the fragment ions at m/z 505 and m/z 521 in the spectrum shown in Figure 10. Thus SFC-MS was used to identify the major peaks in the SFC-FID chromatogram of the octadecanol-reaction-mixtureresidue.
