This summary presents an integrated view of INC-03 through structured tables and a process flow.
H2SO4 Contact Process Flow
Why each step is critical: Step 2 is the rate-limiting equilibrium (V2O5 catalyst, 450°C). Step 3 uses oleum intermediation to prevent acid mist formation.

H2SO4 Property Matrix
| Property | Reagent/Conditions | What Happens | Product |
|---|---|---|---|
| Diprotic acid | Water | 2 released | + HSO4^{-} → 2 + SO4^{2-} |
| Dehydrating | Organic compound, any temp. | Removes H2O | Charred carbon (sugar) or CO (formic acid) |
| Oxidizing | Hot, concentrated | Transfers O, reduces to SO2 | CuSO4 + SO2 (with Cu) |
| Sulfonating | Organic aromatic, hot | Adds -SO3H group | Arene sulfonic acid |
