Is p-Toluenesulfonic acid a strong acid?
p-Toluenesulfonic acid is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). p-Toluenesulfonic acid (PTSA or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH3C6H4SO3H. It is a white solid that is soluble in water, alcohols, and other polar organic solvents.
What is P TsOH?
Illustrated Glossary of Organic Chemistry – Toluenesulfonic acid (p-toluenesulfonic acid; TsOH; p-TsOH) Toluenesulfonic acid (p-toluenesulfonic acid; TsOH; p-TsOH): An aromatic sulfonic acid, often used as a strong acid catalyst.
Is P TsOH an acid?
p-Toluenesulfonic acid (PTSA), or tosylic acid (TsOH), is a corrosive, toxic, solid, strong organic acid. In monohydrate form, its formula is TsOH·H2O.
What is the role of P toluenesulfonic acid?
p-toluene sulfonic acid is widely used as catalyst agent in the synthesis of pharmaceuticals, pesticides, polymerization stabilizer and organic synthesis (esters, etc.), paint intermediates and resin curing agent. And it is also the commonly used acid catalyst in organic synthesis.
How do you dry p toluenesulfonic acid?
p-Toluenesulfonic acid monohydrate was dried at 80 °C under high-vacuum for 48 h. Dry THF, toluene and CH2Cl2 were obtained by using a solvent drying system from Innovative Technologies.
What is the function of TsOH?
TsOH finds use in organic synthesis as an “organic-soluble” acid catalyst. Examples of uses include: Acetalization of an aldehyde. Esterification of carboxylic acids.
Is P-toluenesulfonic acid toxic?
* p-Toluene Sulfonic Acid is a CORROSIVE CHEMICAL and contact can cause severe skin and eye irritation and burns. * Exposure to p-Toluene Sulfonic Acid can irritate the nose, throat and lungs causing burning, dryness and coughing.
Why is TsOH used?
How many G of p-toluenesulfonic acid are there?

How is TsOH converted to p-toluenesulfonate anhydride?
Reactions. TsOH may be converted to p-toluenesulfonic anhydride by heating with phosphorus pentoxide. When heated with acid and water, TsOH undergoes hydrolysis to toluene: CH 3 C 6 H 4 SO 3 H + H 2 O → C 6 H 5 CH 3 + H 2 SO 4. This reaction is general for aryl sulfonic acids. See also.

Why is p-toluenesulfonic acid used in organic dyes?
p-TOLUENESULFONIC ACID MONOHYDRATE. Sulfonic salts are soluble in water. Sulfonic acid and its salts present in organic dyes provide useful function of water solubility and or improve the washfastness of dyes due to their capabiltity of binding more tightly to the fabric. They are widely used in the detergent industry.
How is water removed from p-toluene sulfonic acid?
p-Toluene sulfonic acid is often used as a catalyst in the formation of acetal which water must be removed from the reaction mixture to escape reversible reaction. Water is removed azeotropically by distilation. (Toluene is the solvent). SALES SPECIFICATION APPEARANCE
