On March 15, 2019, the U.S. Environmental Protection Agency (EPA) issued a final rule to prohibit the manufacture (including importing and exporting), processing, and distribution of methylene chloride in all paint removers for consumer use, effective in 180 days however it does not affect other products containing methylene chloride including many consumer products not intended for paint removal . Journals | It is used in the garment printing industry for removal of heat-sealed garment transfers, and its volatility is exploited in novelty items: bubble lights and jukebox displays. Dichloromethane (DCM; mol. Biopharm. It is commonly referred to as "Di-clo.". It is a solvent that has been used in many thermodynamic studies of donor-acceptor bonding. This solvent has a boiling point of 103.3 degrees F. Dichloromethane is used as a solvent. Calculate its molar heat of vaporization The answer is in kilojoules per mole.

[32], In Europe, the Scientific Committee on Occupational Exposure Limit Values (SCOEL) recommends for DCM an occupational exposure limit (8 h time-weighted average) of 100 ppm and a short-term exposure limit (15 min) of 200 ppm. Dichloromethane is primarily used as a solvent in paint removers degreasing agents in electronics manufacturing and many other industrial uses. [11] In the food industry, it has been used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavorings. [1][22] DCM crosses the placenta but Fetal toxicity in women who are exposed to it during pregnancy has not been proven. This is why dichloromethane is widely used as an industrial solvent in order to ensure equipment is stripped of contaminants. 88(2) , 406-14, (2014).

DCM is used in the material testing field of civil engineering; specifically it is used during the testing of bituminous materials as a solvent to separate the binder from the aggregate of an asphalt or macadam to allow the testing of the materials. [33], Concerns about its health effects have led to a search for alternatives in many of these applications.[11][34]. [12], DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. Most hazards of dichloromethane are connected with human health.

In 2009, dichloromethane was produced by 26 manufacturers worldwide and was avail-able from 133 suppliers (NTP, 2011). Its low boiling point also makes it ideal for degreasing temperature sensitive parts. Even though DCM is the least toxic of the simple chlorohydrocarbons, it has serious health risks. Thus, the boiling point of isopropyl alcohol is lower than that of 1-chloropropane. 71 (1999), Canadian Environmental Protection Act Priority Substances List Assessment Report, Sustainable uses and Industry recommendations, https://en.wikipedia.org/w/index.php?title=Dichloromethane&oldid=994997080, GABAA receptor positive allosteric modulators, Articles with dead external links from December 2016, Articles with permanently dead external links, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Creative Commons Attribution-ShareAlike License, -454.0 kJ/mol (from standard enthalpies of formation), None, but can form flammable vapour-air mixtures above ≈100 °C, 25 ppm over 8 hours (time-weighted average), 125 ppm over 15 minutes (, This page was last edited on 18 December 2020, at 17:16.
