What is the structure of p toluenesulfonic acid?

C7H8O3Sp-Toluenesulfonic acid / Formula

Is PTSA a Lewis acid?

PTSA being a Bronsted acid is consumed in the reaction. It has multiple role of maintaining pH of reaction medium as well as catalyst.

What is PTSA catalyst?

p-Toluene sulfonic acid (PTSA)-MCM-41 as a green, efficient and reusable heterogeneous catalyst for the synthesis of jasminaldehyde under solvent-free condition.

What is Tosic acid used for?

Toluenesulfonic acids are used in curing agents for materials such as plastics. These resins have two parts, an A and a B side. The B side, known as the hardener, is the epoxy curing agent. This curing agent reacts with the A side.

What is the density of p toluenesulfonic acid?

1.24 g/cm³p-Toluenesulfonic acid / Density

What is Lewis reagent?

In Lewis acid catalysis of organic reactions, a metal-based Lewis acid acts as an electron pair acceptor to increase the reactivity of a substrate.

Is Tosic acid aromatic?

Toluenesulfonic acid (p-toluenesulfonic acid; TsOH; p-TsOH): An aromatic sulfonic acid, often used as a strong acid catalyst. Most commonly refers to para-methylbenzenesulfonic acid monohydrate (CH3C6H4SO3H.H2O; pKa -2), but the anhydrous form may also be used. Molecular structure of toluenesulfonic acid.

How do you remove soluble acid catalysts?

Washing with low concentrated solution of sodium bicarbonate is good solution, if there is not a salt formulation of your main product during the process. One of the way to recover a homogeneous catalyst is an extraction of product by organic solvent with low boiling temperature.

How do you dry p toluenesulfonic acid?

You can keep a bottle in a discicator containing CaCl2 for drying. I think descicator containing CaCl2 and high vaccum will help to dry it. Dry it over P2O5, in descicator.
