WebAt room temperature, methylene chloride is a clear, colorless liquid with a pleasant odor. It is volatile, producing potentially toxic concentrations at room temperature. It is slightly soluble in water and miscible with most organic solvents. Synonyms include dichloromethane, methylene bichloride, methane dichloride, and methylenedichloride. WebEthylene dichloride occurs as a colorless, oily, heavy liquid that is slightly soluble in water. (1) Ethylene dichloride has a pleasant chloroform-like odor, with an odor threshold of 6-10 ppm. (1) The vapor pressure for ethylene dichloride is 64 mm Hg at 20 °C, and its log octanol/water partition coefficient (log K ow) is 1.48. (1) Conversion ...
