What is Diethyl Ether?

Diethyl ether is an organic compound with the chemical formula C2H5OC2H5. This substance is an ether with two ethyl groups attached to the same central oxygen atom. Diethyl ether is a colourless liquid that is highly volatile and flammable. Furthermore, it has a rum-like, sweet odour. This liquid is very useful as a solvent, a general anaesthetic, and a recreational drug due to its non-toxicity.

Diethyl ether is a functional group isomer of butanol. In other words, both diethyl ether and butanol have the same chemical formula, but diethyl ether has an ether functional group while butanol has an alcohol functional group.

When considering the production of diethyl ether, it is mostly produced as a byproduct of hydration of ethylene during the production of ethanol. Moreover, we can prepare diethyl ether via acid ether synthesis. In this process, we have to mix ethanol with strongly acidic sulfuric acid.

There are many useful applications of diethyl ether. For example, it is important as a solvent in laboratories, as a fuel or a starting fluid, as a general anaesthetic, and as a component in pharmaceutical formulations. However, despite the numerous uses of this compound, it is extremely volatile and flammable. This liquid is also sensitive to light and air; it tends to form explosive peroxides upon the explosion to light and air.

What is Ethyl Acetate?

Ethyl acetate is an organic compound with the chemical formula CH3CH2COOCH3. The molar mass of this substance is 88 g/mol. We can categorize this substance as a carboxylate ester because ethyl acetate forms from the interaction between a carboxylate group and an ethyl group, forming an ester bond. Moreover, Ethyl acetate is the ester of ethanol and acetic acid.

At room temperature, ethyl acetate is a colourless liquid with a fruity odour. This liquid is also widely used as a solvent. Ethyl acetate vapour is heavier than normal air. There is a wide range of applications for this liquid because of its low cost, low toxicity, and pleasant odour.

The melting point of ethyl acetate is -83.6°C, while the boiling point is 77°C. It is a flammable liquid and is an irritant. Moreover, the hydrolysis of Ethyl acetate results in acetic acid and ethanol. This hydrolysis is a two-step process that occurs in the presence of a strong base such as sodium hydroxide (NaOH). The first step involves the formation of ethanol and sodium acetate, whereas the second step involves the conversion of sodium acetate into acetic acid.

What are the Similarities Between Diethyl Ether and Ethyl Acetate?

1. Diethyl ether and ethyl acetate are organic compounds.
