N-propanol (CAS 71-23-8) Uses
N-propanol (CAS 71-23-8), also known as 1-propanol or propanol, is an important organic synthesis solvent and chemical. It has multiple uses and is widely applied in pharmaceuticals, cosmetics, food, agriculture, and industrial sectors. Below are the primary functions and applications of n-propanol:
- As a Solvent: n-propanol can be used directly as a solvent or to synthesize propyl acetate for applications in paint solvents, printing inks, cosmetics, and more. It often serves as a substitute for ethanol with its lower boiling point.
- Pharmaceutical Industry: n-Propanol is used to produce pharmaceutical intermediates like n-propylamine, which are further processed into various drugs. For example, it is used in the production of probenecid, sodium valproate, erythromycin, and other medications.
- Paints and Coatings: n-Propanol is widely used as a solvent in the paint and coatings industry. It aids in the dispersion and dissolution of pigments and resins.
- Cosmetics: In the cosmetics industry, n-propanol serves as a solvent and preservative, contributing to product stability and extended shelf life.
- Pesticide Production: n-Propanol is used to produce pesticide intermediates like di-n-propylamine, which is further processed into pesticides such as aminosulfuron and fenpropathrin.
- Food Additives: Esters synthesized from n-propanol, such as propyl paraben (propyl p-hydroxybenzoate), are commonly used as preservatives in food additives.
- Synthetic Fragrances: n-Propanol and its derivatives are employed in synthesizing various fragrances widely used in food, cosmetics, and household chemicals.
What are the hazards of n-propanol?
N-Propanol is a medium-flash-point flammable liquid with a flash point of approximately 15°C. It may ignite or explode when exposed to open flames or high heat. Store away from ignition sources in a well-ventilated, dry environment. Skin contact may cause mild irritation. For prolonged handling, wear protective gloves and goggles. Avoid inhaling vapors.
