Which of the following is process used for the preparation of acetone?

Options

  1. AHaber process
  2. BWacker process
  3. CWolff-Kishner reduction
  4. DGattermann-Koch synthesis

Correct answer

B. Wacker process

Step-by-step solution

In Wacker process, when mixture of propene and air is passed through mixture of Pd\mathrm{Pd} and CuCl2\mathrm{CuCl}_{2} at high pressure acetone is formed. Pd+CuCl2⟶PdCl2+2CuCl4CuCl+HCl+O2⟶4CuCl2+2H2OCH3\mathrm{Pd}+\mathrm{CuCl}_{2} \longrightarrow \mathrm{PdCl}_{2}+2 \mathrm{CuCl}4 \mathrm{CuCl}+\mathrm{HCl}+\mathrm{O}_{2} \longrightarrow 4 \mathrm{CuCl}_{2}+2 \mathrm{H}_{2} \mathrm{O}\mathrm{CH}_{3}\mathrm{CH}=\mathrm{CH}2+PdCl2+H2O⟶_{2}+\mathrm{PdCl}_{2}+\mathrm{H}_{2} \mathrm{O} \longrightarrow Propane CH3COCH3+Pd+2HCl\mathrm{CH}_{3} \mathrm{COCH}_{3}+\mathrm{Pd}+2 \mathrm{HCl}
