Encyclopedia > Aprotic solvent

In chemistry any solvent that carries hydrogen attached to oxygen as in a hydroxyl group or nitrogen as in a amine group is called a protic solvent. The molecules of such solvents can donate an H+ (proton). Chemistry (in Greek: χημεία) is the science of matter and its interactions with energy and itself (see physics, biology). ... A solvent is a liquid that dissolves a solid, liquid, or gaseous solute, resulting in a solution. ... General Name, Symbol, Number Hydrogen, H, 1 Chemical series nonmetals Group, Period, Block 1 (IA), 1 , s Density, Hardness 0. ... General Name, Symbol, Number Oxygen, O, 8 Chemical series nonmetals Group, Period, Block 16 (VIA), 2, p Density, Hardness 1. ... Hydroxide is a functional group consisting of oxygen and hydrogen: -O−H It has a charge of 1-. The term hydroxyl group is used when the functional group -OH is counted as a substituent of an organic compound. ... General Name, Symbol, Number Nitrogen, N, 7 Chemical series nonmetals Group, Period, Block 15 (VA), 2, p Density 1. ... Ammonia Amines are organic compounds containing nitrogen as the key atom in the amine functional group. ...


Common characteristics:

Examples are water, methanol, ethanol, formic acid, and ammonia. In chemistry, a hydrogen bond is a type of attractive intermolecular force that exists between two partial electric charges of opposite polarity. ... For alternative meanings see acid (disambiguation). ... An ion is an elementary particle or system of elementary particles with a net electric charge. ... ... A lone pair is an electron pair without bonding or sharing with other atoms. ... ... A falling water droplet Water (from the Anglo-Saxon and Low German wæter) is a colourless, tasteless, and odourless substance that is essential to all known forms of life and is the most universal solvent. ... Methanol, also known as methyl alcohol or wood alcohol, is a chemical compound with chemical formula CH3OH. It is the simplest alcohol, and is a light, volatile, colourless, flammable, poisonous liquid that is used as an antifreeze, solvent, fuel, and as a denaturant for ethyl alcohol. ... Ethyl alcohol, also known as ethanol or grain alcohol, is a flammable, colorless chemical compound, one of the alcohols that is most often found in alcoholic beverages. ... Formic acid (systematically called methanoic acid) is the simplest carboxylic acid. ... Ammonia is a chemical compound with the formula NH3. ...



Polar aprotic solvents are solvents that share ion dissolving power with protic solvents but lack acidic hydrogen. These solvents generally have high dielectric constants and high polarity. Overview Dielectrics are usually insulators. ... This article is about the electromagnetic phenomenon. ...


examples are dimethyl sulfoxide, dimethylformamide, and hexamethylphosphorotriamide. Dimethyl Sulfoxide (DMSO, empirically C2H6OS), also known as methyl sulfoxide or sulfinylbismethane, is a chemical compound. ... Dimethylformamide, also known under the names N,N-dimethylformamide and DMF, is a clear, water-miscible liquid and common solvent that is often used in chemical reactions. ...

Solvent Totally Explained (1575 words)
Solvents should therefore not react chemically with the dissolved compounds — they've to be inert.
Solvents can also be used to extract soluble compounds from a mixture, the most common example is the brewing of coffee or tea with hot water.
Common uses for organic solvents are in dry cleaning (for example tetrachloroethylene), as paint thinners (for example toluene, turpentine), as nail polish removers and glue solvents (acetone, methyl acetate, ethyl acetate), in spot removers (for example hexane, petrol ether), in detergents (citrus terpenes), in perfumes (ethanol), and in chemical syntheses.
Method for preparing methyl 2-diphenylmethylsulfinylacetate Number:7,211,684 from the United States Patent and ... (5065 words)
Method according to claim 4, in which the aprotic solvent is chosen from chlorinated solvents, aromatic solvents, hydrocarbon solvents and ethereal solvents.
A given reaction may be carried out in a solvent or in a mixture of several solvents, the solvent(s) being generally chosen according to the type of reaction considered and the subsequent treatment of the reaction medium.
By way of illustration and without limitation of aprotic solvents which may be suitable for the method according to the invention, there may be mentioned in particular chlorinated solvents, aromatic solvents, hydrocarbon solvents and ethereal solvents.
