    Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform-like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents.

    Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2, and ethanol is likely to be the best solvent of those tabulated. However, the latter is polar, and thus we should be very cautions about using just the Hildebrand solubility parameter to make predictions.

    The three aminophenol isomers: Left: 2-Aminophenol (o-aminophenol) Center: 3-Aminophenol (m-aminophenol) Right: 4-Aminophenol (p-aminophenol) Aminophenol may refer to any of three isomeric chemical compounds: 2-Aminophenol; 3-Aminophenol; 4-Aminophenol; They are simultaneously an aniline and a phenol

  8. Bamberger rearrangement - Wikipedia

    en.wikipedia.org/wiki/Bamberger_rearrangement

    The mechanism of the Bamberger rearrangement proceeds from the monoprotonation of N-phenylhydroxylamine 1.N-protonation 2 is favored, but unproductive. O-protonation 3 can form the nitrenium ion 4, which can react with nucleophiles (H 2 O) to form the desired 4-aminophenol 5.

    en.wikipedia.org/wiki/P-Toluenesulfonic_acid

    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
