Solvent for Acid catalyzed alkene hydration
« on: January 16, 2013, 11:36:33 AM »
What is the solvent used for acid catalyzed hydration of alkenes? Water? Aren't alkenes insoluble in water?

Edit: I read a reaction in a book which talks about reaction between Isobutene and water, in presence of small amount of catalyst at 25 degree Celsius. Now, the solvent isn't mentioned. I assume Isobutene at that temperature is gas, while water is in liquid phase. Does it mean isobutene is bubbled through water? Why does bubbling the gas through water cause the reaction, or many reactions to happen? I mean, even the bubbles are in gas phase aren't they? So how is reaction between two different phases occurring so fast?

At the interface? Why not?

How fast?

What Pressure?

If you consider the stoichiometry of reactions involving gas reagents, the gas reagent is usualyl in a huge excess compared to the liquid reagent which is a major driving force for the reaction.  If you are bubbling a gas through a liquid medium, the moles of the gas reagent is essentially infinity.
