p-Toluenesulfonic acid (PTSA or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH3C6H4SO3H. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. The CH3C6H4SO2 group is known as the tosyl group and is often abbreviated as Ts or Tos. Most often, TsOH refers to the monohydrate, TsOH H2O. As with other aryl sulfonic acids, TsOH is a strong organic acid. It is about one million times stron… Il gruppo idrossile (gruppo idrossilico o idrossile secondo la nomenclatura IUPAC, o impropriamente ossidrile o ossidrilione) è un gruppo funzionale di formula -OH caratteristico di idrossidi, alcoli e fenoli, ma presente anche nel gruppo acido carbossilico (-COOH). L'anione ad esso corrispondente, chiamato ione idrossido o ione idrossile, ha formula chimica ed è responsabile della basicità, sia secondo la definizione ormai obsoleta di Arrhenius, sia secondo l…
