A PROCESS FOR DECOMPOSING A COMPLEX MATERIAL CONTAINING A 2:1 COMPLEX OF A TRIALKYLALUMINUM IN WHICH THE ALKYL RADICALS CONTAIN AN AVERAGE OF ABOUT 2 TO 5 CARBON ATOMS AND A COMPOUND HAVING THE FORMULA RNMX, WHEREIN R IS AN ALKYL RADICAL CONTAINING AN AVERAGE OF ABOUT 1 TO 5 CARBON ATOMS; M IS AN ELEMENT SELECTED FROM THE GROUP CONSISTING OF NITROGEN, ARSENIC, PHOSPHORUS, SULFUR, SELENIUM, AND TELLURIUM; X IS A HALOGEN; AND N VARIES FROM 3 TO 4, DEPENDING ON THE PARTICULAR ELEMENT M, WHICH COMPRISES CONTACTING SAID COMPLEX WITH A HYDROCARBON LIQUID FOR A PERIOD OF TIME SUFFICIENT TO REMOVE TRIALKYLALUMINUM FROM THE 2:1 COMPLEX MATERIAL AND AT TEMPERATURE BETWEEN 100 AND 200*C. SUFFICIENT TO REMOVE TRIALKYLALUMINUM FROM SAID 2:1 COMPLEX MATERIAL BUT LESS THAN THE BOILING POINT OF SAID HYDROCARBON LIQUID AT A PRESSURE SUFFICIENT TO MAINTAIN THE HYDROCARBON IN THE LIQUID PHASE.
