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 the chemical formula of p-Toluenesulfonic acid?

C7H8O3Sp-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 PTSA a strong acid?

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….p-Toluenesulfonic acid.

Is PTSA soluble in toluene?

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.

What does TsOH do in a reaction?

TsOH finds use in organic synthesis as an “organic-soluble” strong acid. Examples of uses include: Acetalization of an aldehyde. Fischer–Speier esterification.

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.

How do you remove toluenesulfonic acid?

Impurities can be removed by recrystallization from its concentrated aqueous solution followed by azeotropic drying with toluene. TsOH finds use in organic synthesis as an “organic-soluble” strong acid.
