Abstract
Dialkylaluminum chloride produced as a co-product in the reaction of a trialkylaluminum with zinc chloride or metallic zinc and an alkyl halide, to produce a dialkylzinc, is purified from contaminants containing zinc by contacting it with a dialkylaluminum hydride, followed by distillation.
Claims6
In a process for the production of dialkylzinc compounds by reaction of a trialkylaluminum compound either with zinc chloride or with metallic zinc and an alkyl halide, in which a dialkylaluminum halide is produced as a co-product, the dialkylzinc is removed from the reaction products by distillation, and the dialkylaluminum halide is thereafter removed from the reaction products by distillation, the improvement comprising contacting the dialkylaluminum halide, prior to removal of it by distillation, with a dialkylaluminum hydride.
