A PROCESS FOR PREPARING SULFUR- AND NITROGEN-CONTAINING COMPOSITION WHICH COMPRISES REACTING, AT A TEMPERATURE ABOVE ABOUT 80*C. AND BELOW THE DECOMPOSITION TEMPERATURE, 1.0 MOLE OF AN ALKYLENE AMINE HAVING UP TO ABOUT 8 CARBON ATOMS IN THE ALKYLENE RADICAL WITH AT LEAST ABOUT 0.5 EQUIVALENT OF CARBON DISULFIDE AND AT LEAST ABOUT 1 EQUIVALENT OF A HYDROCARBON-SUBSTITUTED DICARBOXYLIC ACID HAVING AT LEAST ABOUT 12 ALIPHATIC CARBON ATOMS IN THE HYDROCARBON RADICAL, THE TOTAL NUMBER OF NITROGEN RADICALS IN SAID ALKYLENE AMINE BEING AT LEAST AS GREAT AS THE TOTAL NUMBER OF EQUIVALENTS OF CARBON DISULFIDE AND SAID DICARBOXYLIC ACID, AND REMOVING THE WATER FORMED BY THE REACTION.
