Application

Ethylbenzene may be used as a starting material to synthesize:
  • Acetophenone via selection oxidation in the presence of potassium dichromate supported on neutral alumina and using air as the oxidizing agent.
  • Styrene via dehydrogenation over nanodiamonds in an oxygen-lean environment.

A novel nanodiamond/CNT-SiC monolith catalyst has been prepared by a facile two-step approach. The as-synthesized monolith afforded high activity and stability for ethylbenzene direct dehydrogenation to styrene, showing its potential application as a metal free catalyst in gaseous catalytic reactions.

Several organic solvents have anticonvulsant or convulsant actions depending on the dose and exposure time. To study if there is a structure-activity relationship for organic solvents as anticonvulsant agents we subjected independent groups of mice to a single 30-min exposure
