ABSTRACT:
The hydrocarbon solvent contained in a solution of an organoaluminum compound is recovered by a process comprising contacting the solution with water at a volume ration of from about 3:1 to about 8:1. Preferably, the solvent is n-hexane, the organoaluminum compound is triethylaluminum sesquichloride, and the solution has been used in a process for preparing olefin polymerization catalysts.
