2-Ethylhexanol with H2SO4
« on: June 26, 2020, 02:30:16 PM »
Hello chemists,

please, is 2-ethyl-1-hexen  formed by the reaction of 2-ethylhexan-1-ol with sulfuric acid?

Thank you. Lukáš S.

It sure is possible, but it's also, or even more, important to check if this would be the major product. After all, if another product is more favorable and this one ends up forming only 1% of the final product mixture, the reaction is pretty much useless.

So, take one step back: what sort of reaction occurs here? What are the possible product? Which "rules" exist for this case?

This is a primary alcohol and elimination is more difficult, even secandary alcohols need 130° with H2SO4.
