### Acid Catalyzed Esterification

Adding Acetic anhydride (C4H6O3) to Vanillin (C8H8O3) with H2SO4.
Does anyone know what the balanced equation would look like? I know the product is supposed to be C12H14O6 but I'm not exactly sure for the equation.

Could it be C4H6O3 + C8H8O3 + H2SO4 = C12H14O6 + H2SO4 ?

Please write formula with functional groups. Your equation is wrong.
Vanilin is a Phenol derivate. So the ester can only happen at the OH group.

Adding Acetic anhydride(C4H6O3) to Vanillin(C8H8O3) with Sulfuric acid(H2SO4).

If I am correct, the balanced equation is 8C4H6O3(aq) +5C8H8O3(aq) + 39H2SO4(aq) → 11C3H8(g)(Propane) + 39H2CO3(aq)(Carbonic Acid) + 39O2(g)(dioxygen) +39S(s)(Sulfur)

Please dont post this kind of nonsense.
Read how esters normaly are made. The sulfuric acid is catalyst and is not nominal involved.

### Re: Acid Catalyzed Esterification

I used online chemical equations balancing calculator and input therin the reacant side of this chemical reaction with some products with appropriate stoichiometric coefficients as well.

So, as a result, I secured the above balanced equation. So, i posted it here as an answer.

Sorry for posting wrong answer to this question.

### Re: Acid Catalyzed Esterification

This is not a matter of a balance calculator. Its more to have the right knowledge whats going on.

The basic here is (CH3CO)2O + ROH => CH3COOR + CH3COOH
