ABSTRACT:
High-purity trimethylaluminum has the following impurity contents: organosilicon components≦0.5 ppm, chlorine components≦20 ppm, hydrocarbon components≦1,000 ppm, Ca≦0.05 ppm, Fe≦0.05 ppm, Mg≦0.05 ppm, Na≦0.05 ppm, Si (Si components other than the organosilicon components)≦0.07 ppm, Zn≦0.05 ppm, and S≦0.05 ppm. The high-purity trimethylaluminum can be obtained by removing impurities from crude trimethylaluminum through distillation and evaporation.
