Can h2 reduce benzene
WebThe limits are commonly called the "Lower Explosive or Flammable Limit" (LEL/LFL) and the "Upper Explosive or Flammable Limit" (UEL/UFL). The lower and upper explosion concentration limits for some commonly used gases are indicated in the table below. Some of the gases are commonly used as fuel in combustion processes. Note! WebBenzene reacts with Hydrogen in the presence of a catalyst such as Rhodium, platinum, or Raney Nickel to form Cyclohexane. In the reaction, 3 moles of hydrogen is added to the double bonds to yield saturation. The reaction is: Hence, Benzene reacts with H 2 in presence of Ni at 2000C to give Cyclohexane.
