Title: Is conc. hydrochloric acid strong for dehydrating alcohol to ether?
Post by: lukas.stib on April 03, 2021, 03:44:12 AM

Hi chemists,

I synthesized n-chloropropane from conc. 35 - 37% hydrochloric acid, anhydrous ZnCl2 and n-propanol by refluxed for 4 hours, and I noticed that apart from the sweet smell of n-chloropropane I smelled a very smell very similar to di-n-propyl ether. Is it possible that hydrochloric acid is strong enough to dehydrate propanol to reflux for a given ether? (I always thought that only sulfuric acid was strong enough to dehydrate primary alcohols to ethers). If so, I expect that when I produce other primary chloroalkanes by this process, the corresponding ether will also be formed, which will be removed by fractional distillation of the chloroalkane.

Thank you, Lukáš S.

I think you can get some ether this way. You should not sniff alkylhalides, they can give cancer.
