| Abstract | THE OBJECTIVE WAS TO IDENTIFY AS MANY COMPONENTS IN THE C10 AND HEAVIER RANGE OF REFORMED PETROLEUM PRODUCTS AND TO UTILIZE TO THE FULLEST EXTENT POSSIBLE THE CAPABILITIES OF THE MASS SPECTROMETRIC INTERFACE IN IDENTIFYING THE CAPILLARY GC PEAKS. IT WAS POSSIBLE TO ISOLATE THE C10-C11 FRACTIONS FROM A TYPICAL REFORMATE AND THE C11-C14 FRACTION FROM AN ALKYLATED REFORMATE. THE MAJOR PEAKS APPEARING IN THE CAPILLARY GC OF THE C10-C11 CUT (21 PEAKS) WERE IDENTIFIEDAND 95 PERCENT (13 PEAKS) IN THE C11-C14 FRACTION WERE IDENTIFIED. THE C10-C11 FRACTION WAS ISOLATED BY PREPARATIVE GAS CHROMATOGRAPHY USING A 5-1/2 FT COLUMN PACKED WITH OV-1 ON CHROMOSORB P. THIS FRACTION WAS INJECTED INTO A 200 FT COLUMN WITH (M-PHENOXY, PHENOXY) BENZENE/SQUALANE AND PROGRAMMED FROM 50 TO 90C AT 1C PER MINUTE. THE C11-C14 FRACTION WAS ISOLATED BY DISTILLATION OF COMPONENTS BOILING ABOVE 187 C. THE DISTILLATE WAS INJECTED IN A 150-FT COLUMN COATED WITH POLYPHENYL ETHER AND PROGRAMMED FROM 50 TO 160 C AT 5 C PER MINUTE. MASS SPECTRA WERE OBTAINED AT 70 EV WITH AN IONIZING CURRENT OF 150 MICRO AMPS. THE GC PEAKS WERE SCANNED AT 2 SEC PER DECADE FOR THE C10-C11 FRACTION AND 4 SEC PER DECADE FOR THE C11-C14 DECADE. THE CHROMATOGRAMS, FORMULAS, COMPOUND NAMES, AND BOILING POINTS OF THE FRACTIONS ARE LISTED. (LITTLE-BATTELLE) |
