Pass the resulting gaseous products through a series of wash bottles containing potassium hydroxide (KOH) solution to remove acidic impurities like carbon dioxide and maleic anhydride vapors. Secure the tube within the furnace zone, ensuring it is properly sealed to prevent gas leakage.
Coke Bottle CO2 Reaction: Creating Carbon Suboxide (2CO2)
Carbon suboxide has the molecular formula C3O2 and presents as a colorable gas at room temperature, often possessing a strong, unpleasant odor reminiscent of garlic or acrid smoke. This process requires heating maleic anhydride to temperatures between 300°C and 400°C in the presence of a catalyst, typically phosphorus pentoxide (P2O5) or silica gel.
The reaction forces the removal of a water molecule from the maleic anhydride structure, rearranging the atoms into the C3O2 configuration. Understanding how to make 2CO2 begins with recognizing that this specific chemical notation refers to carbon suboxide, a distinct molecule from the more common carbon dioxide (CO2).

Gradually heat the mixture to a temperature of 360°C, maintaining this temperature for approximately 30 to 60 minutes to ensure complete reaction. This method is favored for its relatively high yield and the availability of starting materials, though it demands precise temperature control to prevent unwanted byproducts.
