Catalytic Hydrogenation
« on: October 02, 2010, 02:47:02 PM »
Why can the use of high temperatures in the catalytic hydrogenation of alkenes to alkanes be self-defeating ?

What are the economic/industrial uses of alkanes and alkenes? Which is the most commercially valuable raw material an alkane or alkene?

Because the higher the temperature, the more likely a dehydrogenation back to the alkene will take place!
