Explain why a phase transfer catalyst is used when oxidizing methoxybenzyl alcohol

Chemistry

Phase transfer catalyst is used when oxidizing methoxybenzyl alcohol because it is able to dissolve in both the ethyl acetate and the aqueous layers.

What is phase transfer catalyst?

A phase-transfer catalyst, often known as a PTC, is a catalyst that helps a reactant move from one phase into another where a reaction takes place. Heterogeneous catalysis features a unique subset known as phase-transfer catalysis.

In the absence of a phase-transfer catalyst, ionic reactants are frequently soluble in an aqueous phase but insoluble in an organic phase. When introducing salts into the organic phase, the catalyst acts as a detergent. When a phase-transfer catalyst is added, the reaction is said to be catalyzed, which means it is accelerated.

Pentane is a small liquid hydrocarbon, between propane and gasoline in size at C5H12. The density of pentane is 0.626 g/mL and i
Goshia [24]

Answer : The fuel value and the fuel density of pentane is, 49.09 kJ/g and 3.073\times 10^4kJ/L respectively.

Explanation :

Fuel value : It is defined as the amount of energy released from the combustion of hydrocarbon fuels. The fuel value always in positive and in kilojoule per gram (kJ/g).

As we are given that:

\Delta H^o_{comb}=-3535kJ/mol

Fuel value = \frac{\Delta H^o_{comb}}{\text{Molar mass of pentane}}

Molar mass of pentane = 72 g/mol

Fuel value = \frac{3535kJ/mol}{72g/mol}

Fuel value = 49.09 kJ/g

Now we have to calculate the fuel density of pentane.

Fuel density = Fuel value × Density

Fuel density = (49.09 kJ/g) × (0.626g/mL)

Fuel density = 30.73 kJ/mL = 3.073\times 10^4kJ/L

Thus, the fuel density of pentane is 3.073\times 10^4kJ/L
