How is diethyl ether prepared from ethyl bromide and ethyl alcohol?

Answer 1

#"Diethyl ether"# from #"ethyl bromide.........."#?

What about "ethyl alcohol" and "ethyl bromide" along with a small amount of non-nucleophilic base?

#"H"_3"CCH"_2"Br" + "HOCH"_2"CH"_3 stackrel("base")rarr "H"_3"CCH"_2"OCH"_2"CH"_3+"base"*"HBr"#

Naturally, you need to locate a helpful base.

Given the product's volatility and flammability, there would definitely be effective industrial preparation, carried out under very strict guidelines.

Diethyl ether can be prepared from ethyl bromide and ethyl alcohol through an acid-catalyzed dehydration reaction. The reaction proceeds as follows:

[ \text{C}_2\text{H}_5\text{Br} + \text{C}_2\text{H}_5\text{OH} \xrightarrow{\text{H}_2\text{SO}_4} \text{C}_2\text{H}_5\text{OC}_2\text{H}_5 + \text{HBr} ]

Here, sulfuric acid (( \text{H}_2\text{SO}_4 )) serves as the catalyst for the reaction, leading to the formation of diethyl ether (( \text{C}_2\text{H}_5\text{OC}_2\text{H}_5 )) and hydrogen bromide (( \text{HBr} )).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
