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.

Why is Psoso catalyst?

The ability to recover and reuse the catalyst from the reaction mixtures, minimal generation of environmentally unfriendly waste, high specificity of the reaction, and the low cost are important advantages of the TsOH catalyst over the other conventional Friedel−Crafts catalysts.

Is PTSA a Lewis acid?

PTSA being a Bronsted acid is consumed in the reaction. You can separate Lewis acid catalysts but Bronsted acid and other organoacids cannot be separated which is the main demerit of these catalysts.

What is the chemical formula of p-Toluenesulfonic acid?

C7H8O3S
p-Toluenesulfonic acid/Formula

Is p-Toluenesulfonic acid soluble in water?

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.

Is TsOH a base?

As with other aryl sulfonic acids, TsOH is a strong organic acid. It is about one million times stronger than benzoic acid. It is one of the few strong acids that is solid and therefore is conveniently weighed and stored.

What is the pKa of p-Toluenesulfonic acid?

p-Toluenesulfonic acid

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.

Is the tosyl group soluble in water or alcohol?

It is a white solid that is soluble in water, alcohols, and other polar organic solvents. The CH 3 C 6 H 4 SO 2 group is known as the tosyl group and is often abbreviated as Ts or Tos.

Which is the monohydrate of the tosyl group?

The CH 3 C 6 H 4 SO 2 group is known as the tosyl group and is often abbreviated as Ts or Tos. Most often, TsOH refers to the monohydrate, TsOH. H 2 O. As with other sulfonic acids, TsOH is a strong organic acid.

What is the CAS number for toluene 4 sulfonic acid monohydrate?
