Method of preparing hydrocarbyl-substituted heterocyclic nitrogen compounds,reaction products prepared thereby and compositions containing same

Abstract

Abstract APLHA-HYDROCARBYL OR BETA-HYDROCARBYL MONO-AND DIS LACTAMS, HYDROCARBYL TETRAHYDROPYRROLIDINES AND MIXTURES THEREOF ARE OBTAINED BY THE STEPS OF REDUCING A MALEIC ANHYDRIDE-OLEFIN ADDUCT WITH A METAL OR AMMONIUM HYDRIDE, IN THE PRESENCE OF A SOLVENT OF WHICH THE SAID ANHYDRIDE IS NOT ASSOCIATED, AND REACTING THE RESULTING PRODUCT WITH AN AMIDE, SUCH AS ALKYLENE-POLYAMINE, TO PRODUCT THE RESULTING PRODUCT. ALTERNATIVELY, THE MALEIC ANHYDRIDE-OLEFIN ADDUCT IS REACTED WITH THE AMINE OR POLYAMINE TO PRODUCE THE CORRESPONDING IMIDO OR BIS-IMIDO TYPE PRODUCT, FOLLOWED BY THE SAID REDUCING STEP. THE MALICE ANHYDRIDE-OLEFIN ADDUCT OF PARTICULAR INTEREST IS AN ALKENYLSUCCINIC ANHYDRIDE, PREFERABLY IN WHICH THE ALKENYL GROUP IS A RADICAL OF FROM ABOUT 6 TO ABOUT 600, AND PREFERABLY FROM ABOUT 20 TO ABOUT 300, CARBON ATOMS. THE PRODUCTS OF THIS INVENTION HAVE UTILITY AS DETERGENTS OT DISPERSANTS IN INDUSTRIAL ORGANIC FLUIDS, SUCH AS LUBRICATING OILS, AND FUELS. THE ALSO ACT AS NEUTRALIZING AGENTS, ANTICORROSION AGENTS AND THE LIKE.
