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.
