Make up the reaction equation: Propane-propene-propyne-acetone-carbon dioxide

1. The reaction of dehydrogenation.
C3H8 = C3H6 + H2 (reaction condition nickel and temperature).
When hydrogen is split off from propane, the result is propene.
2. The reaction of dehydrogenation.
C3H6 = C3H4 + H2 (reaction conditions temperature and nickel).
When hydrogen is split off from propene, the result is propyne.
3. Kucherov’s reaction.
C3H4 + H20 = CH3-C (0) -CH3 (mercury salt catalyst).
As a result, acetone is formed.
4. Combustion reaction.
CH3-C (0) -CH3 + 4O2 = 3CO2 + 3H20.
The result is carbon dioxide and water.
