| abstract | WHERE R IS HYDROGEN OR W-AMINOALKYL OF FROM 1 TO 5 CARBONS AND A MONOETHOXYLATED HYDROLYZED POLYALKENEA2S5 REACTANT, SAID DERAVATIVE PREPARED BY: (A) FIRST CONTACTING AN ALIPHATIC POLYALKENE OF AN AVERAGE MOLECULAR WEIGHT OF BETWEEN ABOUT 50 AND 5000 WITH P2S IN THE PRESENCE OF SULFUR AT A FIRST ELEVATED TEMPERATURE, (B) SECOND CONTACTING THE RESULTING POLYALKENE-P2S5 REACTION PRODUCT WITH STEAM AT A SECOND ELEVATED TEMPERATURE, (C) REMOVING INORGANIC PHOSPHORUS ACID FROM THE STEAM TREATED (HYDROLYZD) POLYALKENE-P2S5 REACTION PRODUCT, (D) THIRD CONTACTING THE INORGANIC ACID FREE, STEAM TREATED POLYALKENE-P2S5 REACTION PRODUCT WITH ETHYLENE OXIDE AT A THIRD ELEVATE TEMPERATURE IN A MOLE RATIO OF SAID INORGANIC ACID FREE, STEAM TREATED P2S5POLYALKENE REACTION PRDUCT TO SAID ETHYLENE OXIDE OF BETWEEN ABOUT 1:1 AND 1:1.5 TO FORM SAID MONOETHOXYLATED REACTANT, (E) FOURTH CONTACTINGTHE ETHOXYLATD DERIVATIVE WITH SAID AZIRIDINE AT A FOURTH ELEVATED TEMPERATURE UTILIZING A MOLE RATIO OF SAID DERIVATIVE TO SAID AZIRIDINE OF BETWEEN ABOUT 3:1 AND 1:2 TO FORM SAID DETERGENT-DISPERSANT DERIVATIVE. R-N<(-(CH2)2-) AN AZIRIDINE DETERGENT-DISPERSANT DERIVATIVE, LUBE OIL COMPOSITIONS CONTAINING SAID DERIVATIVE, AND MANUFACTURE THEREOF, SAID DERATIVE BEING THE REACTION PRODUCT OF AN AZIRIDINE OF THE FORMULA: |
