Abstract
Disclosed is a method for refining trimethylsilane, including the steps of (1) preparing an activated carbon loaded with at least copper (II) oxide and zinc oxide; (2) adsorbing a trimethylsilane onto the activated carbon; and (3) bringing a trimethylsilane containing silane, methylsilane or dimethylsilane as an impurity into contact with the activated carbon finished with the step (2) to remove the impurity from the trimethylsilane by adsorbing the impurity. According to this method, heat generation of the activated carbon is suppressed and impurities such as dimethylsilane, etc. can be removed efficiently.
