For haloalkanes, the boiling point is basically related to the molecular weight. Dichloromethane (aka methylene chloride) has been a useful sovlent for decades; but its significant hazards have caused it to be used in a declining number of applications. Dichloromethane CAS RN: 75-09-2 Boiling Point. [33], Concerns about its health effects have led to a search for alternatives in many of these applications.[11][34]. This solvent has a boiling point of 103.3 degrees F. Dichloromethane is an organic compound which has a sweet aroma and is used widely as a solvent. Melting point −35 °C (−31 °F; 238 K) Boiling point: 84 °C (183 °F; 357 K) Guidechem provides Dichloromethane chemical database query, including CAS registy number 75-09-2, Dichloromethane MSDS (Material Safety Data Sheet), nature, English name, manufacturer, function/use, molecular weight, density, boiling point, melting point, structural formula, etc. DICHLOROMETHANE reacts vigorously with active metals such as lithium, sodium and potassium, and with strong bases such as potassium tert-butoxide. Boiling Point: 39.8°C. Parts cleaning is an essential process in many industries. Biopharm.

Eur. The liquid will attack some forms of plastic, rubber and coatings. More... Validated by Experts, Validated by Users, Non-Validated, Removed by Users. The donor hydrogen-bonding corrections of methylene chloride in these thermodynamic studies has been reported. It is a volatile liquid (that is, it evaporates quickly). Production and imports of dichloromethane in the USA totalled 45 000–227 000 tonnes between 1996 and 2006 ( NTP, 2011). Vapour Density: 2.93. [12], DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. dichloromethane molecules "hold together" stronger and thus evaporate at a higher temperature. This is why dichloromethane is widely used as an industrial solvent in order to ensure equipment is stripped of contaminants. Research is not yet clear as to what levels may be carcinogenic. In February 2013, the U.S. Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health warned that at least 14 bathtub refinishers have died since 2000 from DCM exposure. 2011). J. Pharm. 1361 , 265-76, (2014). Specific Gravity: 1.3255. These compounds are separated by distillation. DCM was first prepared in 1839 by the French chemist Henri Victor Regnault (1810–1878), who isolated it from a mixture of chloromethane and chlorine that had been exposed to sunlight.[13]. Articles of Dichloromethane are included as well. A. Its low boiling point also makes it ideal for degreasing temperature sensitive parts. Hence, the given set of compounds can be arranged in the increasing order of their boiling points as: … Biopharm. the vapor pressure of ethanol at its normal boiling point would be 1)80 kPa 2)101.2 kPa 3)273 kPa 4)373 kPa would it be 1 ? *Please select more than one item to compare. MSDS/SDS Database Search | Urinary metabolic fingerprinting of mice with diet-induced metabolic derangements by parallel dual secondary column-dual detection two-dimensional comprehensive gas chromatography. Ozone concentrations measured at the midlatitudes from the ground up through the stratosphere from 1998 to 2016 have declined by 2.2 Dobson units. Revised on 09/26/2018 Page 1 of 7 Safety Data Sheet Methanol 5% in Dichloromethane 1. 00095. [28] In animal experiments, it was fetotoxic at doses that were maternally toxic but no teratogenic effects were seen. Dichloromethane, de uterated. [18], Dichloromethane extract of Asparagopsis taxiformis, a seaweed fodder for cattle, has been found to reduce their methane emissions by 79%.[19]. The chemical compound's low boiling point allows the chemical to function in a heat engine that can extract mechanical energy from small temperature differences. highest to lowest boiling point isopropanol, 1-butene, CCl4, dichloromethane(CH2Cl2), propane Calculate its molar heat of vaporization The answer is in kilojoules per mole. Dichloromethane is a clear liquid with low viscosity at room temperature and has a high index of refraction (1.4244) giving it a shiny appearance. Dichloromethane. Melting/freezing point at 101 325 Pa provides information on the substance melting/freezing point in °C at a pressure of 101 325 Pa.

Find chemicals information Dichloromethane at guidechem, professional and easy to use. [37] The reasons for this decline are unclear, but one unverified hypothesis is the presence of short-lived substances such as dichloromethane in the lower atmosphere.

Boiling Point: 39.6±0.0 °C at 760 mmHg Vapour Pressure: 448.0±0.0 mmHg at 25°C Enthalpy of Vaporization: 28.1±0.0 kJ/mol Flash Point:-14.1±22.4 °C Index of Refraction: Most hazards of dichloromethane are connected with human health. Chemsrc provides Dichloromethane(CAS#:75-09-2) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Dichloromethane (DCM; mol. Article No. Thus, the boiling point of isopropyl alcohol is lower than that of 1-chloropropane. 93.328) was first prepared in 1840 by mixing chloromethane and chlorine and exposed to sunshine. Methylene chloride is a Lewis acid that can hydrogen bond to electron donors. 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.

[14] Its volatility has led to its use as an aerosol spray propellant and as a blowing agent for polyurethane foams. Dichloromethane is used as a solvent. It is a solvent that has been used in many thermodynamic studies of donor-acceptor bonding. Journals | [17] It is also used as the fluid in Christmas lights that have the colored bubbling tube above a lamp as a source of heat and a small amount of rock salt to provide thermal mass and a nucleation site for the phase changing solvent. DCM's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products. It is incompatible with strong oxidizers, strong caustics and chemically active metals such as aluminum or magnesium powders. The normal boiling point of dichloromethane is 40C. In the European Union, the total tonnage band for dichloromethane was reported The boiling point does not have anything to do with breaking bonds. It has a sweet smell similar to that of chloroform. Arrange the following compounds in order from highest to lowest boiling point. 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.
