Correct answer: A. Catalytic dehydrogenation of ethyl benzene
- A. Catalytic dehydrogenation of ethyl benzene
- B. Dehydration of ethyl alcohol followed by hydrogenation
- C. Reacting ethylene oxide with acetaldehyde
- D. Fermentation of starch
Explanation
Industrial styrene is produced mainly by catalytic dehydrogenation of ethylbenzene: C6H5CH2CH3 yields C6H5CH=CH2 plus hydrogen. The other choices do not represent the commercial route.
