Class Information
Number: 44/343
Name: Fuel and related compositions > Liquid fuels (excluding fuels that are exclusively mixtures of liquid hydrocarbons) > Heterocyclic carbon compound containing a hetero ring having chalcogen or nitrogen as the only ring hetero atoms > The hetero ring contains five members including nitrogen and carbon (e.g., pyrrolidones, porphines, etc.) > Plural nitrogens in the hetero ring (e.g., imidazolines, etc.) > At least three nitrogens in the hetero ring (e.g., triazoles, tetrazoles, etc.)
Description: Compositions wherein the five-membered hetero ring has three or four nitrogen ring members.
