  • Process for purification of monosilane
    Patent number: 8506682
    Abstract: Provided is a method of purifying monosilane. More particularly, the method includes removing impurities from a crude material containing monosilane and ethylene by fractional distillation (operation 1), and removing ethylene and residual impurities by passing the crude material purified in operation 1 through activated carbon (operation 2). According to the method, high-purity monosilane may be more simply and effectively obtained without additional production of byproducts by selectively adsorbing ethylene, which is difficult to separate by fractional distillation, using an activated carbon.
