A: The direct dehydrogenation process of cyclohexane requires high reaction temperatures, which can lead to carbon chain fragmentation or extensive coking. This process also suffers from poor product selectivity and a short catalyst lifespan.
A: Cyclohexene is an ideal raw material for synthesizing cyclohexanol, cyclohexanone, and adipic acid, which are in high demand in the chemical fiber industry. It is also widely used in the production of fine chemicals such as pharmaceuticals, pesticides, dyes, detergents, feed additives, and polyester.
