Patent ID: 8236981

Claim:
A method for manufacturing dialkylzinc and dialkylaluminum monohalide by reacting zinc halide with trialkylaluminum, comprising: reacting the zinc halide with the trialkylaluminum to form a mixture containing reaction products, wherein the trialkylaluminum contains aluminum trihydride, a monoalkylaluminum dihydride, a dialkylaluminum monohydride, and combinations thereof at a total concentration of 0.01% by mass to 0.10% by mass; distilling the mixture to obtain dialkylzinc containing aluminum in not more than 10 parts per million (ppm) by mass as a first distillate; distilling a still residue to separate all remaining dialkylzinc from the still residue as a second distillate; and distilling the still residue to separate dialkylaluminum monohalide containing zinc of not more than 10 ppm by mass as a third distillate.
