A solvent dissolves a solute, resulting in a solution Ethyl acetate, a nail polish solvent. [1] A solvent (from the Latin solvÅ, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid.
Hydrophobic fluorinated ionic liquids, such as organic salts of bistriflimide or hexafluorophosphate, can form phases that are insoluble in both water and organic solvents, producing multiphasic liquids. Fluorine-containing compounds are often featured in noncoordinating or weakly coordinating anions.

Diethyl azodicarboxylate, conventionally abbreviated as DEAD and sometimes as DEADCAT, [6] [7] is an organic compound with the structural formula CH 3 CH 2 −O−C(=O)−N=N−C(=O)−O−CH 2 CH 3. Its molecular structure consists of a central azo functional group, RN=NR, flanked by two ethyl ester groups. This orange-red liquid is a valuable ...
p-Toluenesulfonic acid (PTSA, pTSA, or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH 3 C 6 H 4 SO 3 H. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. [6] The CH 3 C 6 H 4 SO 2 group is known as the tosyl group and is often abbreviated as Ts or Tos.
The VOC Solvents Emissions Directive was the main policy instrument for the reduction of industrial emissions of volatile organic compounds (VOCs) in the European Union. It covers a wide range of solvent-using activities, e.g. printing, surface cleaning, vehicle coating, dry cleaning and manufacture of footwear and pharmaceutical products.
It is miscible with water and many organic solvents. [11] Dihydrolevoglucosenone has a boiling point of 226 °C at 101.325 kPa (vs 202 °C for NMP), and a vapor pressure of 12.98 Pa near room temperature (25 °C). [1] It has a comparatively high dynamic viscosity of 14.5 cP (for comparison DMF: 0.92 cP at 20 °C, NMP: 1.67 cP at 25 °C). [12]
It is a colorless or white solid that is soluble in many organic solvents but reacts with water and alcohols. The compound is used to protect alcohols in organic synthesis. [1] tert-Butyldimethylsilyl chloride reacts with alcohols in the presence of base to give tert-butyldimethylsilyl ethers: [2] [3] (Me 3 C)Me 2 SiCl + ROH → (Me 3 C)Me 2 ...
