Acetone vs. Isopropanol
What's the Difference?
Acetone and isopropanol are both commonly used solvents with similar chemical properties. However, they have some key differences. Acetone is a colorless liquid with a strong odor, while isopropanol is a clear, colorless liquid with a milder odor. Acetone is more volatile and flammable than isopropanol, making it a better choice for quick-drying applications. Isopropanol, on the other hand, is less toxic and more commonly used in medical and cosmetic products due to its antiseptic properties. Overall, both solvents have their own unique uses and benefits depending on the specific application.

Further Detail
Introduction
Acetone and isopropanol are two commonly used solvents in various industries and household applications. While both are effective in dissolving substances, they have distinct attributes that make them suitable for different purposes. In this article, we will compare the properties of acetone and isopropanol to understand their differences and similarities.
Chemical Composition
Acetone, also known as propanone, has the chemical formula CH3COCH3. It is a colorless, volatile liquid with a characteristic odor. On the other hand, isopropanol, also known as isopropyl alcohol, has the chemical formula C3H8O. It is a colorless, flammable liquid with a strong odor similar to rubbing alcohol.
Solubility
Acetone is highly soluble in water, alcohol, ether, and most organic solvents. It is a versatile solvent that can dissolve a wide range of substances, making it ideal for cleaning and degreasing applications. Isopropanol is also soluble in water and most organic solvents, but it is less polar than acetone. This makes isopropanol a better solvent for dissolving oils, greases, and other non-polar substances.
Flammability
Both acetone and isopropanol are flammable liquids with low flash points. Acetone has a flash point of -20°C, while isopropanol has a flash point of 11.7°C. This makes them highly volatile and poses a fire hazard if not handled properly. It is important to store acetone and isopropanol in a cool, well-ventilated area away from sources of ignition.
Toxicity
Acetone is considered to be less toxic than isopropanol. While both solvents can cause irritation to the skin, eyes, and respiratory tract, isopropanol is more harmful if ingested. Isopropanol can cause nausea, vomiting, and central nervous system depression if consumed in large quantities. Acetone, on the other hand, is metabolized by the liver into harmless byproducts, making it less toxic when ingested.
Uses
Acetone is commonly used as a solvent in nail polish removers, paint thinners, and cleaning agents. It is also used in the production of plastics, fibers, and pharmaceuticals. Isopropanol is widely used as a disinfectant, antiseptic, and solvent in pharmaceuticals, cosmetics, and personal care products. It is also used in the manufacturing of rubbing alcohol and hand sanitizers.
Conclusion
In conclusion, acetone and isopropanol are two versatile solvents with distinct properties that make them suitable for different applications. While acetone is highly soluble and less toxic, isopropanol is more effective at dissolving non-polar substances and has better disinfectant properties. Understanding the differences between acetone and isopropanol can help in choosing the right solvent for specific tasks and ensuring safe handling practices.
