    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.

  7. Azeotropic distillation - Wikipedia

    en.wikipedia.org/wiki/Azeotropic_distillation

    In organic chemistry, some dehydration reactions are subject to unfavorable but fast equilibria. One example is the formation of dioxolanes from aldehydes: [9] RCHO + (CH 2 OH) 2 RCH(OCH 2) 2 + H 2 O. Such unfavorable reactions proceed when water is removed by azeotropic distillation.
