Zusammenfassung:	PURPOSE:To obtain the title dehydrating composition having excellent water removing performance, by adding trifluoroethanol to freon-113 in a specified ratio. CONSTITUTION:From 10-25wt% trifluoroethanol is added to 1,1,2-trichloro-1,2,2- trifluoroethane (freon-113) to obtain the dehydrating composition. The composition has excellent water removing performance, and can also be used for dehydrating an article, the surface of which must be precisely cleaned. Besides, various stabilizers such as nitromethane, which are ordinarily used for freon-113 and alcoholic solvents, can also be added to the composition.
