The purpose is to provide is a method for removing silanol with good efficiency from a raw material of disilicon hexachloride containing silanol as an impurity, to thereby prepare a high purity disilicon hexachloride. A method for purifying disilicon hexachloride including a step of contacting a raw material of disilicon hexachloride containing disilicon hexachloride and silanol as an impurity with an adsorbing material such as an activated carbon, to remove the silanol. The method may further includes a distillation step. It is preferred that the above steps are carried out in an atmosphere of an inert gas.
