Methylene Chloride Chemical Properties,Uses,Production

Description

Also known as methylenedichloride and dichloromethane,CH2Cl2 is a colorless, volatile liquid with a penetrating ether-like odor that is soluble in alcohol and ether,and slightly soluble in water. Non-flammable and nonexplosive in air. Derivation is the chlorination of methylchloride and subsequent distillation. It is used in paint removers,solvent degreasing, plastics processing. blowing agent in foams, solvent extraction, solvent for cellulose acetate,and as an aerosol propellant.

Uses

Pharmaceutic aid (solvent).

Industrial uses

Methylene chloride has been suggested, and indeed is already in commercial use, as a substitute for chlorofluorocarbon auxiliary blowing agents. Methylene chloride is highly volatile (boiling point 39.8°C) and inert in polyurethane-forming mixtures. However, methylene chloride is a suspected carcinogen and has other deleterious effects on workers exposed to it. Accordingly, the concentration of methylene chloride in the air inside a foam plant must be kept low. The American Conference of Governmental Industrial Hygienists recommends that workers not be exposed to more than 50 ppm of the chemical, while the Occupational Safety and Health Administration’s Permissible Exposure Limit is 500 ppm. Keeping the levels of methylene chloride in a foam plant below 50 ppm may require additional ventilation equipment, with an associated increase in costs. In addition, the chemical is a recognized environmental pollutant, and both the federal and state governments are beginning to limit releases of the chemical from plants that employ it. Thus, in the near future, plants using methylene chloride as an auxiliary blowing agent may be faced with the substantial additional expense of installing scrubbers or similar equipment to remove methylene chloride from air and/or other gases discharged from the plant. In addition, California has recently proposed that emissions of methylene chloride in that state be subject to a heavy “pollution” tax, and other states are likely to follow a similar course.
