    摘要: Compounds useful as additives in hydrocarbon fuels are prepared by reacting urea with a nitrogen-heterocyclic substituted alcohol, for example an organylimidazolinyl substituted alcohol, in the presence of an organic solvent. The reaction products are carbamates containing, for example, organylimidazolinyl substituents. Hydrocarbon fuel compositions containing these additives exhibit enhanced carburetor detergency and have other beneficial multifunctional properties of value to combustion improvement.
