Aniline (from Portuguese anil 'indigo shrub', and ine indicating a derived substance) is an organic compound with the formula C 6 H 5 NH of a phenyl group (−C 6 H 5) attached to an amino group (−NH 2), aniline is the simplest aromatic is an industrially significant commodity chemical, as well as a versatile starting material for fine chemical synthesis.
The effect is particularly well seen with lime. Minute amounts of calcium hydroxide enhance the solubility of quartz, but large amounts almost completely depress it. Lime is not very soluble in water, but it is soluble enough to give a solution which is centinormal in alkalinity and has a pH of about 12.
According to Henry's law, for an ideal solution the solubility, Cg, of a gas ( × 10 −3 mol L −1, in this case) is directly proportional to the pressure, Pg, of the undissolved gas above the solution ( kPa in this case). Because both Cg and Pg are known, this relation can be rearranged and used to solve for k .
Phenol, or Benzenol, (also known as carbolic acid or phenolic acid) is an aromatic organic compound with the molecular formula C 6 H 5 OH. It is a white crystalline solid that is molecule consists of a phenyl group (−C 6 H 5) bonded to a hydroxy group (−OH).Mildly acidic, it requires careful handling because it can cause chemical burns.. Phenol was first extracted from coal ...
Coal tar is completely or nearly completely soluble in benzene and nitrobenzene and it is partially soluble in acetone, carbon disulfide, chloroform, diethyl ether, ethanol, methanol, petroleum ether, hexane, and sodium hydroxide solution, and slightly soluble in water. It has a characteristic naphthalenelike odor.
EXPERIMENTAL 600 mg of ground coal samples ( < 60 ^m) were placed in cylindrical glass tubes (d= 10 mm, /=60 mm) giving a height of coal powder of approximately 20 mm (/1;). ml solvent was added. The mixture was shaken well once per day.

The 87 Sr/ 86 Sr isotopic ratios of watersoluble Sr from coal ash have been applied to delineate the impact of coal ash effluents on the aquatic environment for scenarios where the 87 Sr/ 86 Sr ratios of the watersoluble Sr were different from those of background water (Harkness et al., 2016; Ruhl et al., 2014; Vengosh et al., 2016 ...
A simple investigation of the water solubility of nanoparticles based on chitosan proved that such a potential carrier increases the solubility of curcumin in the hydrophilic solution. The solubility of curcumin in water ( μg/mL) after encapsulation into chitosan nanoparticles was improved up to 180 mg/mL.
Graphite (/ ˈ ɡ r æ f aɪ t /) is a crystalline form of the element consists of stacked layers of occurs naturally and is the most stable form of carbon under standard and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and high pressures and temperatures it converts to ...
The cocoa powder was characterized in terms of solubility, wettability, fat content, pH, color properties and particle size. The protocol of Dogan et al. was used as the reference of the solubility and wettability analyses. The solubility test was performed by adding 4 g of the cocoa powder into 40 ml of water (80 °C).
The watersoluble Sr (, in gypsum) in the highGe coal (Ge concentrations: 451170 ppm, 273 ppm on average, whole coal basis) has ⁸⁷Sr/⁸⁶Sr values in the range of to 0. ...
Geochemical processes and the effects of natural organic solutes on the solubility of selenium in coalmine backfill aquifers were investigated. Backfill and groundwater samples were collected at coal mines in the Powder River Basin, Wyoming. Backfill was generally dominated by aluminum (14,400 to 49,000 mg/kg (milligrams per kilogram)), iron (3,330 to 23,200 mg/kg), and potassium (7,950 to 18,00
Naphthalene is the most abundant single component of coal tar. The composition of coal tar varies with coal type and processing, but typical coal tar is about 10% naphthalene by weight. In industrial practice, distillation of coal tar yields an oil containing about 50% naphthalene, along with twelve other aromatic compounds.
Water temperature can have a significant effect on the solubility of compounds. Refer to the chart below to find reference values per gram of common compounds and salts (with chemical formula) at six temperatures of 100 g of water from 0 degrees to 100 degrees Celsius. The content and density of the total solution at 20 degrees are also provided.
Urea, also called carbamide (because it is a diamide of carbonic acid), is an organic compound with chemical formula CO(NH 2) amide has two amino groups ( NH 2) joined by a carbonyl functional group (C(=O)). It is thus the simplest amide of carbamic acid.. Urea serves an important role in the metabolism of nitrogencontaining compounds by animals and is the main nitrogen ...
Watercoal interactions are dominant factors that affect water quality in coal mines. Using lixiviation, the effects of watercoal interactions on pH, salinity, and hazardous elemental enrichment in coal mine water and associated trends were simulated and analyzed. The salinity and hazardous element contents were low in the alkaline solution filtrate. However, the salinity and contents of ...
1 Introduction Coal fly ash (CFA), also known as pulverized fuel ash, is finely divided mineral residue obtained from powdered coal combustion in thermal power plants. During the process of burning, temperature may go above 1600 °C and most of the inorganic materials present in the coal get melted.
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca() is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed with has many names including hydrated lime, caustic lime, builders' lime, slaked lime, cal, and pickling hydroxide is used in many applications, including food ...
Quinoline is a typical nitrogenous organic compound commonly seen in the petroleum, coal tar, coal gas and oil shale processing industries. It is widely used as a raw material and solvent in the dye, paint, fungicide and woodprocessing industries (Padoley et al. 2008; Rameshraja Srivastava 2012; Wang et al. 2016).However, quinoline is a risk to the environment and humans due to being highly ...
solubility, degree to which a substance dissolves in a solvent to make a solution (usually expressed as grams of solute per litre of solvent). Solubility of one fluid (liquid or gas) in another may be complete (totally miscible;, methanol and water) or partial (oil and water dissolve only slightly).In general, "like dissolves like" (, aromatic hydrocarbons dissolve in each other ...
