Abstract
A process is disclosed for the recovery of dialkylaluminum halides from a mixture containing dialkylaluminum halides and soluble zinc containing compounds by heating the mixture to pyrolyze the zinc compounds down to acceptable levels and subsequently distilling the alkylaluminum halide from the heated mixture.
Claims7
A process for the recovery of dialkylaluminum halides having from 1 to 6 carbon atoms from a mixture of the alkylaluminum halide and soluble zinc-containing compounds which comprises heating the mixture in an inert atmosphere at a temperature of about 150.degree.-240.degree.C. for a period of time sufficient to reduce the concentration to 200 ppm or lower zinc, and subsequently distilling the alkylaluminum halide from the mixture in an inert atmosphere.
