hcl solubility in dichloromethane

DCM should be stored in dark glass bottles, away from light or any heat sources. 31), and Wright et al. On average, 3 - 5 measurements were taken at each temperature. Solubility [100 w1] = 58.838 – 0.38224 ( T /K) + 6.3928 × 10 –4 ( T /K) 2. Although it is not miscible with water, it is polar, and miscible with many organic solvents. Web site owner: 14), Davies et al. The solubility measurements cover the 253 to 313 K temperature These compounds are separated by distillation. While some brands do contain nearly pure DCM, many more contain dichloromethane along with some other solvents; these may or may not be easily purified by distillation. 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. It is not miscible in water. Unless specified, the DCM is considered water-free. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products. trend of temperature dependence of solubility and are rejected; however, the It is also the principal component of paint stripper, although replacements exist. 15), Kudryavtseva and Krutikova (ref. The table below provides information on the of solubility of different substances in dichloromethane, at different temperatures, at 1 atmosphere of pressure. 34), McGovern (ref. Dichloromethane (DCM or methylene chloride) is an organochloride compound with the formula CH2Cl2. [14] Its volatility has led to its use as an aerosol spray propellant and as a blowing agent for polyurethane foams. Last updated: February 18, 2015 (Created: August 17, 2007), Privacy Policy / Security Notice / Accessibility Statement, Solubility of CH2Cl2 in 20% HCl solution. 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=984473910, 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 20 October 2020, at 07:59. The data of Sabinin et al. 19), Antropov et al. In countries where DCM isn't available, a very similar substitute, 1,2-Dichloroethane, can often be found. are damaged, end user should discontinue use 1) are markedly lower than the other results and are therefore rejected. ... in connection with this information. these chemicals are present. (3) Distilled (compiler). Units of solubility are given in grams per 100 grams of solvent (g/100 g). versus temperature behavior is discussed in the Preface. Aspirin is an orally administered non-steroidal antiinflammatory agent. The salt will be much more soluble in water than in dichloromethane so when the aqueous solution comes in contact with the dichloromethane, the sodium move into the aqueous layer where it will be better solvated. seams and closures have shorter breakthrough times and higher permeation DuPont makes no from the permeation behavior of the individual chemicals. Distributed by the Office of Data and Informatics of the National Institute of Standards and Technology After 2-3 hours  the solution became saturated and samples were taken periodically (ref. Unless specified, the methanol is considered anhydrous. The solubilities of tetracycline hydrochloride, moxifloxacin hydrochloride, and ciprofloxacin hydrochloride were measured in several solvents, such as water, ethanol, 2-propanol, and acetone, in the temperature range of 293.15−323.15 K for ciprofloxacin.HCl and moxifloxacin.HCl and 288.15−310.15 K for tetracycline. (refs. More severe consequences can include suffocation, loss of consciousness, coma, and death. of DuPont or others covering any material or its use. 15), and Kudryavtseva and Krutikova (ref. This process can also be done to produce more highly chlorinated chloromethanes from lower ones, meaning chloromethane (methyl chloride) can be chlorinated to produce dichloromethane, trichloromethane, and carbon tetrachloride. determine the level of toxicity and the proper personal protective It is a solvent that has been used in many thermodynamic studies of donor-acceptor bonding. Units of solubility are given in grams per 100 grams of solvent (g/100 g). The solubility of water (2) in dichloromethane (1) has been reported from 19 laboratories. 10), van Arkel and Vles (ref. The output of these processes is a mixture of chloromethane, dichloromethane, chloroform, and carbon tetrachloride as well as hydrogen chloride as a byproduct. 379, http://www.sciencemadness.org/smwiki/index.php?title=Dichloromethane&oldid=10571, Chemical pages without CAS Registry Number, Chemical pages without DrugBank identifier, Articles containing unverified chemical infoboxes, GNU Free Documentation License 1.3 or later, None, but can form flammable vapour-air mixtures above 100 °C. Often sold as a main component of plastic welding adhesives, it is also used extensively by model building hobbyists for joining plastic components together.
