Chapter 2—Solvents Used in Cold Cleaning


Solvents encountered in cold cleaning applications include: methylene chloride, 1,1,1-trichloroethane, trichloroethylene, perchloroethylene, O-di-chlorobenzene, monochlorobenzene, trichlorofluoromethane, trichlorotrifluoroethane, and blends of one or more of the halogenated solvents with other chemical solvents, such as petroleum fractions, alcohols, ketones, esters, and ethers. Some of the more important properties of these materials are: Methylene chloride (dichloromethane, methylene dichloride) A colorless, heavy, nonflammable, highly volatile, low boiling liquid possessing excellent solvent power for greases, oils, waxes, and many other organic compounds. Its low boiling point makes it especially suitable in applications where a fast evaporation rate is required.
