Class Information
Number: 44/347
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.) > Acyclic chalcogen bonded directly to each carbon adjacent to the ring nitrogen (e.g., succinimides, etc.)
Description: Compositions wherein each carbon adjacent to the ring nitrogen of the five-membered hetero ring is bonded directly to acyclic chalcogen (i.e., oxygen, sulfur, selenium, or tellurium).
