Role of Hot water and Sulfuric Acid in Esterfication?
« on: December 18, 2006, 01:50:17 PM »
Hello,

In class, we added glacial acetic acid to amyl alcohol, then sulfuric acid.  Before heating, it had the distinct smell of permanant marker.  After heating, it smelled of banannas.  What role did the hot water bath (65 Degrees Celcius) and the Sulfuric acid play in the reaction?

Thanks you in advance.

For the role of sulfuric acid read:

Sulfuric acid also helps by destroying water.  How would the presence of water negatively affect your yield?

For the role of the hot water bath, think of how temperature affects reaction rates.
