Introduction

In the chemical industry, there are various substances that are used in different processes. In this article we are going to talk about two substances widely used in this field: diethyl ether and petroleum ether. Even though they are both ethers, there are a number of differences that distinguish them. Next, we will explain what each of them is and the differences that exist between them.

Diethyl ether

Diethyl ether, also known as ethoxyethane, is a colorless, volatile liquid that is used as a solvent in the chemical and pharmaceutical industry. It is a highly flammable substance and is mainly used as an anesthetic. in medicine. In the chemical industry, it is used as a solvent in the extraction of organic products.

Chemical properties of diethyl ether

• Its chemical formula is C₄H₁₀O.
• It has a density of 0,713 g/cm³.
• Its boiling point is 34,6 °C.
• It is soluble in water and most organic solvents.

Petroleum ether

Petroleum ether, also known as petether, is a flammable and volatile liquid used in industry as a solvent. It is obtained from the distillation of petroleum and its main use is as a solvent for fats and oils in the chemical, pharmaceutical and cosmetic industries.

Chemical properties of petroleum ether

• Its chemical formula is C₅H₁₂O.
• It has a density of 0,7 g/cm³.
• Its boiling point is 35°C to 40°C.
• It is insoluble in water and soluble in most organic solvents.

Differences between diethyl ether and petroleum ether

Although both compounds are used as solvents in the chemical and pharmaceutical industries, there are certain differences between them that distinguish them. Some of these differences are:

• Diethyl ether is more flammable than petroleum ether.
• Petroleum ether is obtained from the distillation of petroleum, while diethyl ether is produced through chemical reactions.
• Diethyl ether is used as an anesthetic in medicine, while petroleum ether has no medical use.
• Diethyl ether is soluble in water, while petroleum ether is insoluble in water.

Conclusion

In summary, diethyl ether and petroleum ether are two substances used in the chemical and pharmaceutical industries as solvents. Although both compounds are ethers, there are notable differences between them that distinguish them. It is important to take these differences into account to choose the right compound for each process in the industry.
