The status of knowledge about the nonbasic nitrogen compounds in petroleum is reviewed. Pyrroles, indoles, carbazoles, benzocarbazoles, phenazines, benzonitriles, and amides have been identified in petroleum or its fractions boiling above 400/sup 0/F. Nonbasic nitrogen can be divided into four subtypes by titration of the crude oil with perchloric acid in acetic anhydride before and after reduction with lithium aluminum hydride. This method requires no prior separation or concentration of the nitrogen, and provides more detailed information than previous methods. Future interest in nonbasic nitrogen lies in identification of classes of compounds in the heavier ends of crude oil.
