WebThe most common strong acid used for dehydration is concentrated sulfuric acid, even though phosphoric acid and p-toluenesulfonic acid (abbreviated as TsOH) are often used as well. The reaction can follow both E1 and E2 mechanisms depending on whether it is a primary, secondary or a tertiary alcohol. WebIt is a white 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. It is a white solid that is soluble in water, alcohols, and other polar organic solvents . Structure
