How dense is dichloromethane

WebSolubility and miscibility describe similar phenomena, but they are not the same. Solubility exists on a spectrum. Substances may combine together poorly or very well, and it's possible to describe solutions as "partially soluble" or "mostly soluble." Miscibility, however, is an absolute property that is not expressed in degrees. WebChapter 5.7 Dichloromethane Air Quality Guidelines - Second Edition WHO Regional Office for Europe, Copenhagen, Denmark, 2000 2 DCM values were generally highest in winter, declined to a minimum in April and increased in the autumn (6,7). Mean background concentrations in rural areas are 0.07–0.29 µg/m3 .
