Nitrogen compounds of Colorado shale oil

Book ·
OSTI ID:7219248

The nitrogen bases of Colorado shale oil from oil shale near DeBeque (Colo.) that distilled below 300/sup 0/C were principally tertiary amines of the pyridine homolog type. Fractions boiling below 300/sup 0/C contained symmetrical collidine and 2-methyl 5-ethyl pyridine but no quinoline or isoquinoline. The higher-boiling tertiary amines contained longer substituted side chains and were partially unsaturated. Secondary amines, which corresponded to the substituted pyrroles and piperidines, were present in the crude bases. There was also a trace of acid nitriles present; however, primary amines were not present in amounts greater than 1 percent. The composition of the nitrogen bases boiling below 300/sup 0/C resembled those of low-temperature coal tar, except for the absence of quinolines, isoquinolines, hydrogenated quinolines, and hydrogenated isoquinolines.
