Isopropyl alcohol, also known as isopropanol, has the chemical formula C3H8O. It is a colorless, flammable liquid with a strong odor. Propanol, on the other hand, refers to either n-propanol or isopropanol. N-propanol has the chemical formula C3H7OH, while isopropanol has the formula C3H8O. Both isopropyl alcohol and propanol are alcohols, but they have different chemical structures.

Isopropyl alcohol has a boiling point of 82.6 degrees Celsius and a melting point of -89 degrees Celsius. It is soluble in water and miscible with most organic solvents. Propanol, on the other hand, has a boiling point of 97.2 degrees Celsius and a melting point of -126 degrees Celsius. It is also soluble in water and miscible with organic solvents. Both isopropyl alcohol and propanol are highly flammable liquids.

Isopropyl alcohol is commonly used as a disinfectant, antiseptic, and solvent. It is often found in household cleaning products, hand sanitizers, and medical wipes. Propanol, specifically n-propanol, is used as a solvent in the pharmaceutical and cosmetic industries. Isopropanol, on the other hand, is used in the production of acetone and as a solvent in the manufacturing of pharmaceuticals and cosmetics.

Isopropyl alcohol is considered toxic when ingested in large quantities. It can cause nausea, vomiting, and central nervous system depression. Propanol, specifically n-propanol, is also toxic when ingested and can cause similar symptoms. Isopropanol, on the other hand, is less toxic than n-propanol and is often used as a safer alternative in certain applications.

Both isopropyl alcohol and propanol are highly flammable liquids. They should be stored in a cool, well-ventilated area away from sources of ignition. Isopropyl alcohol has a flash point of 11.7 degrees Celsius, while propanol has a flash point of 21 degrees Celsius. It is important to handle these substances with care to prevent accidents.

In conclusion, isopropyl alcohol and propanol are both useful chemicals with different properties and applications. Isopropyl alcohol is commonly used as a disinfectant and solvent, while propanol is used as a solvent in various industries. Both substances are flammable and toxic if ingested. It is important to understand the differences between isopropyl alcohol and propanol to use them safely and effectively.
