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.

It is frequently used as a recrystallization solvent, as many organic compounds exhibit good solubility in hot cyclohexane and poor solubility at low temperatures. Cyclohexane is also used for calibration of differential scanning calorimetry (DSC) instruments, because of a convenient crystal-crystal transition at −87.1 °C.
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.
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 ...
N,N′-Dimethylpropyleneurea (DMPU) is a cyclic urea sometimes used as a polar, aprotic organic solvent. Along with the dimethylethyleneurea, it was introduced as an analog of tetramethylurea. [2] In 1985, Dieter Seebach showed that it is possible to replace the suspected carcinogen hexamethylphosphoramide (HMPA) with DMPU. [3]
1,2,6-Hexanetriol is used as a solvent, for raising the viscosity of liquid and semi-solid cosmetic [9] and pharmaceutical preparations due to its low toxicity and good compatibility, and as a humectant due to its hygroscopicity. [3] 1,2,6-hexanetriol improves the effectiveness of the active ingredients as an adjuvant in crop protection ...
For a cleaner product, the reaction is conducted in the gas phase or in an organic solvent. Ethylene fluorohydrin is obtained differently, by boiling hydrogen fluoride with a 5–6% solution of ethylene oxide in diethyl ether. The ether normally has a water content of 1.5–2%; in absence of water, ethylene oxide polymerizes. [37]
