What would happen if the sulfuric acid was left out in the reaction between acetic anhydride and salicylic acid to prepare acetylsalicylic acid?

Because Salicylic Acid reacts with Acetic Anhydride in the presence of H2SO4 and CH3COOH to give Aspirin. The sulphuric acid does not react. If you measure the volume/weight of the acid before the reaction and after the reaction, there will be no change. Note:-
You can also use Acetyl Chloride in the presence of phosphoric acid instead on Acetic Anhydride.

∙ 14y agoSulfuric acid is used as a catalyst in the reaction, so if it was not included the reaction would either occur at a greatly reduced rate or not at all.

What is the common name of sulfur trioxide?
Sulfuric anhydride
Is sulfur trioxide harmful?
Yes, it is, as it is very reactive, oxidizing and anhydride of Sulfuric acid.
Can sulfuric acid react with the alkaline gas?
Yes,they can undergo a neutralization reaction, the reaction between sulfuric acid and ammonia is feasible.
Can salicylic acid be used on cats?
No it upsets the solfuric acid in the stomach [Q to answerer. Are you sure of sulfuric acid rather than hydrochloric?]
What is the reaction called when sulfuric acid turns black and what is the reaction called?
Sugar Dehydration occurs when sugar is added to sulfuric acid, in the reaction the sugar is broken down into graphite which is black and bubbles with the escaping vapor. This reaction is a exothermic reaction.
How do salicylic acid and acetic anhydride react to form aspirin in a base mechanism?
Salicylic acid + acetic anhydride react to form acetylsalicylic acid (aspirin) + acetic acid. This reaction is performed in acidic conditions ( normally by adding sulfuric acid) and is heated.
Common name for sulfur trioxide?
Sulfuric anhydride
What is the common name of sulfur trioxide?
Sulfuric anhydride
Which is the anhydride of sulfuric acid?
Sulfur trioxide - SO3 + H2O -----> H2SO4
Is sulfur trioxide harmful?
Yes, it is, as it is very reactive, oxidizing and anhydride of Sulfuric acid.
What is the acid an-hydride of sulfuric acid?
Sulphuric anhydride is H2S2O7,... H2SO4 + H2SO4-----> H2S2O7 + H2O
What is the mechanism involved in Liebermann- Burchard test?
When conc. sulfuric acid is added to cholesterol, a water molecule is removed from C3 of cholesterol molecule, and it is oxidised to form3,5-cholestadiene.This product is converted to a polymer containing a chromophore which results in the green colouration indicating a positive test.
Can sulfuric acid react with the alkaline gas?
Yes,they can undergo a neutralization reaction, the reaction between sulfuric acid and ammonia is feasible.
H2SO4 in aspirin?
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.
