Chemical Structure

3-Butoxypropan-2-ol, also known as butoxypropanol, has a chemical formula of C7H16O2. It is a clear, colorless liquid with a molecular weight of 132.20 g/mol. Isopropanol, on the other hand, has a chemical formula of C3H8O and is also a clear, colorless liquid. It has a molecular weight of 60.10 g/mol. The chemical structures of these two compounds are quite different, with 3-Butoxypropan-2-ol containing a butoxy group and Isopropanol containing an isopropyl group.

Physical Properties

3-Butoxypropan-2-ol has a boiling point of 174°C and a melting point of -70°C. It is slightly soluble in water and miscible with organic solvents. Isopropanol, on the other hand, has a boiling point of 82.6°C and a melting point of -89°C. It is completely miscible with water and most organic solvents. Both compounds have a characteristic alcohol odor, but Isopropanol is known for its strong smell compared to 3-Butoxypropan-2-ol.

Uses

3-Butoxypropan-2-ol is commonly used as a solvent in various industries, including paint, coatings, and cleaning products. It is also used as a coupling agent in agricultural formulations. Isopropanol, on the other hand, is widely used as a disinfectant, antiseptic, and solvent. It is commonly found in household products such as rubbing alcohol, hand sanitizers, and cleaning agents. Both compounds have antimicrobial properties, making them effective in killing bacteria and viruses.

Toxicity

3-Butoxypropan-2-ol is considered to be a mild irritant to the skin and eyes. Prolonged or repeated exposure may cause dermatitis or other skin conditions. Inhaling high concentrations of the vapor may also cause respiratory irritation. Isopropanol, on the other hand, is known to be more toxic than 3-Butoxypropan-2-ol. It can cause irritation to the skin, eyes, and respiratory tract. Ingesting Isopropanol can lead to poisoning, with symptoms such as dizziness, nausea, and vomiting.

Environmental Impact

3-Butoxypropan-2-ol is considered to have low toxicity to aquatic organisms. However, it may persist in the environment and bioaccumulate in aquatic organisms. Isopropanol, on the other hand, is known to be highly toxic to aquatic life. It can cause harm to fish and other aquatic organisms if released into water bodies. Both compounds are biodegradable and can be broken down by microorganisms in the environment.

Regulatory Status

3-Butoxypropan-2-ol is not classified as a hazardous substance by regulatory agencies such as the Environmental Protection Agency (EPA) in the United States. However, it is important to follow safety guidelines when handling this compound to minimize exposure. Isopropanol, on the other hand, is classified as a hazardous substance by regulatory agencies due to its toxicity. It is important to use Isopropanol in well-ventilated areas and wear appropriate personal protective equipment.
