What is toluenesulfonic acid used for?
What is toluenesulfonic acid used for?
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.
What is TsOH organic chemistry?
TsOH finds use in organic synthesis as an “organic-soluble” strong acid. Examples of uses include: Acetalization of an aldehyde.
What is the structure of p toluenesulfonic acid?
C7H8O3S
p-Toluenesulfonic acid/Formula
Why is P-toluenesulfonic acid used in this reaction?
And it is also the commonly used acid catalyst in organic synthesis. The use of p-toluenesulfonic acid also catalyzes the protection of dihydrofuran on the alcohol, carboxylic acid esterification, transesterification reaction, making the aldehyde generate acetal.
Is P-toluenesulfonic acid polar?
It 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….3D Structure for HMDB0059933 (p-Toluenesulfonic acid)

How does sulfonation occur?
Sulfonation is a reversible reaction that produces benzenesulfonic acid by adding sulfur trioxide and fuming sulfuric acid. The reaction is reversed by adding hot aqueous acid to benzenesulfonic acid to produce benzene.
Is P toluenesulfonic acid corrosive?
* 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.
Is P toluenesulfonic acid polar?
Is p-toluenesulfonic acid soluble in water?
TERRESTRIAL FATE: p-Toluenesulfonic acid is a strong acid (pKa = -1.34(1)) and is completely dissociated and highly soluble (about 620 g/L(2)) in water. It would be expected to leach fairly rapidly. Its biodegradation in soil is unknown(SRC).
What is the molecular weight of p-toluenesulfonic acid monohydrate?

What is toluene-4-sulfonic acid?
(USCG, 1999) Toluene-4-sulfonic acid is an arenesulfonic acid that is benzenesulfonic acid in which the hydrogen at position 4 is replaced by a methyl group. It is a member of toluenes and an arenesulfonic acid. It is a conjugate acid of a toluene-4-sulfonate.
How do you convert TsOH to p-toluenesulfonate?
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.
