Vanadium pentaoxide
Sulphuric acid can act as a catalyst in some organic reactions. It is often used in esterification reactions to help drive the reaction forward by protonating the reacting species and increasing their reactivity.
Vanadium pentoxide (V2O5) is commonly used as a catalyst in the manufacture of sulfuric acid by the contact process. It helps to speed up the reaction of sulfur dioxide with oxygen to produce sulfur trioxide, which is then converted into sulfuric acid.
Sulphuric acid is used as a catalyst in esterification reactions to increase the rate of the reaction by providing protons that can assist in forming the ester product. It helps in protonating the carbonyl oxygen of the carboxylic acid, making it more susceptible to nucleophilic attack by the alcohol.
Because the esterification process is reversible, and we need the reaction to be one-way, the addition of sulphuric acid as a dehydrating agent stops the water from reacting with the ester to form back into an acid and alcohol. The sulphuric acid also acts as a catalyst for the reaction by protonating the carbonyl group oxygen, thus making the carbonyl group more electrophilic
Its primary use is in the Contact Process (making Sulphuric Acid). This can be done directly by reacting Sulphur Trioxide with Water to form dilute, but highly corrosive, Sulphuric Acid: SO3(g) + H2O(l) = H2SO4(aq) It can also be achieved indirectly by adding Sulphur Trioxide to Sulphuric Acid to form Disulphuric Acid (Pyrosulphuric Acid, Fuming Sulphuric Acid or Oleum) then Reacting Disulphuric Acid with Water to Form Concentrated Sulphuric Acid: SO3(g) + H2SO4(l) = H2S207(l) H2S2O7(l) + H20(l) = 2H2SO4(l)
Sulphuric acid can act as a catalyst in some organic reactions. It is often used in esterification reactions to help drive the reaction forward by protonating the reacting species and increasing their reactivity.
The catalyst commonly used in making polyesters is an esterification catalyst, such as an acid catalyst like sulfuric acid or an organic acid like p-toluenesulfonic acid. These catalysts help facilitate the reaction between the diol and the dicarboxylic acid to form the polyester polymer.

because sulphuric acid stops reaction
Because the esterification process is reversible, and we need the reaction to be one-way, the addition of sulphuric acid as a dehydrating agent stops the water from reacting with the ester to form back into an acid and alcohol. The sulphuric acid also acts as a catalyst for the reaction by protonating the carbonyl group oxygen, thus making the carbonyl group more electrophilic
to ensure that all the sulphuric acid has been used up

Yes. ^ Well to improve on this, in simple terms. A catalyst is something that brings on the reaction, in this case the liquid catalyst can only contain a little amount of water otherwise side reactions will occur and this would impact (reduce) the yield of aspirin - not good, sulfuric acid is usually used because it is 98% pure, phosphoric acid can also be used but it is only about 85% pure, still OK. HCL in its most concentrated form is only 37% pure and there fore no good at all. In a shorter to the point answer, H2SO4 is a pure catalyst which will give you a close to accurate yield of aspirin.
No, sulphuric acid is used.
Sulfuric acid is used in the preparation of methyl salicylate as a catalyst to promote the esterification reaction between salicylic acid and methanol. It helps to increase the reaction rate and yield of the desired product. Additionally, sulfuric acid aids in the removal of water formed during the reaction to shift the equilibrium towards the formation of methyl salicylate.
