Question

Balance the redox equation for the oxidation of p-xylene to terephthalic acid using H₂CrO₄:

How many milligrams of H₂CrO₄ are required to oxidize 75.0 mg of p-xylene to terephthalic acid?

science chemistry

Answer 1

Answer #1

Oxidation half reaction

p-xylene + H₂O terephthalic acid + 6 H⁺ + 6 e^-

Reduction half-reaction

H₂CrO₄ + 6 H⁺ + 3 e^- Cr³⁺ + 4 H₂O

Total reaction

C₈H₁₀ + 2 H₂CrO₄ + 6 H⁺ C₈H₆O + 2 Cr³⁺ + 7 H₂O

milligrams of H₂CrO₄ = 1.67 x 10³ mg (or 167 mg)

Terephthalic acid (TPA) is synthesized from -xylene (PX) in the process C8H10 +302 – C8H6O4 +2H2O shown below. A fresh feed of pure liquid PX combines with a recycle stream containing PX and a solution (S) of a catalyst (a cobalt salt) in a solvent (methanol). The combined stream, which contains S and PX in a 3:1 mass ratio, is fed to a reactor in which 90% of the PX is converted to TPA. A stream of air at 25...
