Overview

N Propyl Alcohol (1-propanol) is a primary alcohol with the molecular formula C₃H₈O and CAS number 71-23-8. This clear, colorless liquid with a characteristic alcohol-like odor serves as a crucial component in numerous industrial processes and laboratory applications. With excellent solubility properties and miscibility with water, N Propyl Alcohol functions effectively as both a solvent and chemical intermediate across diverse industries.

Key Applications

  • Industrial Solvent: Widely used in manufacturing processes for dissolving resins, oils, and other organic compounds in paint, coating, and adhesive formulations
  • Chemical Synthesis: Serves as an important intermediate in the production of propyl esters, ethers, and other specialty chemicals
  • Coatings and Inks: Essential component in printing inks, surface coatings, and industrial finishes due to its excellent flow and leveling properties
  • Laboratory Reagent: Commonly utilized in analytical chemistry and research applications for extraction, purification, and reaction processes

Safety & Handling

N Propyl Alcohol has a flash point of 15°C, classifying it as a flammable liquid requiring careful handling procedures. Always use appropriate personal protective equipment including safety glasses, chemical-resistant gloves, and protective clothing. Ensure adequate ventilation in work areas to prevent vapor accumulation. Keep away from heat sources, sparks, and open flames. The autoignition temperature is 390°C, and proper grounding procedures should be followed during transfer operations.

Storage & Shelf Life

Store N Propyl Alcohol in tightly sealed containers made of compatible materials such as steel or glass. Maintain storage temperatures below 25°C in a cool, dry, well-ventilated area away from incompatible materials including strong oxidizing agents and acids. The product has an extended shelf life when stored properly in original, unopened containers. Regular inventory rotation using first-in-first-out principles ensures optimal product quality.

Frequently Asked Questions

What is n-Propyl Alcohol (1‑propanol) and what is it used for?
n-Propyl alcohol (1‑propanol, CAS 71-23-8, formula C3H8O) is a primary alcohol solvent and chemical intermediate. It is commonly used as an industrial solvent, laboratory reagent, intermediate in organic synthesis, and in coatings, adhesives and cleaning formulations.
How should n‑Propyl Alcohol be stored and what is its typical shelf life?
Store in a cool, dry, well‑ventilated area away from heat, sparks and oxidizing agents in tightly closed, grounded containers. Typical unopened shelf life is 12–24 months depending on grade and container; consult the Certificate of Analysis (COA) for specific expiry information.
What are the key safety and handling precautions for n‑Propyl Alcohol?
n‑Propyl alcohol is a flammable liquid and can cause eye and respiratory irritation; use in a well‑ventilated area, keep away from ignition sources, and wear appropriate PPE (gloves, goggles, flame‑resistant clothing). Refer to the Safety Data Sheet (SDS) for first aid, firefighting measures and exposure limits before use.
What concentrations and purity grades of n‑Propyl Alcohol are available and how do they differ?
Available grades range from technical/industrial (≈95%+) to reagent/analytical (≥99%) and anhydrous (water ≤0.1% or dried to specification). Higher purity/anhydrous grades are required for sensitive syntheses and analytical work, while technical grades suit general solvent applications.
What product documentation can I request for n‑Propyl Alcohol?
Standard documentation includes the Safety Data Sheet (SDS), Certificate of Analysis (COA), Technical Data Sheet (TDS) and, when applicable, regulatory declarations (REACH, RoHS) and GC/MS purity reports. These documents are provided on request or with shipments.
How is n‑Propyl Alcohol typically shipped and packaged?
It is shipped as a flammable liquid under applicable transport regulations (DOT/IMDG/IATA) and is commonly packaged in steel drums, intermediate bulk containers (IBCs), and smaller HDPE or glass bottles. Ensure proper labeling, grounding/bonding for bulk transfers and compliance with local carrier requirements.
Is n‑Propyl Alcohol compatible with common materials and packaging?
n‑Propyl alcohol is generally compatible with carbon steel, stainless steel, polyethylene and polypropylene, but can attack some elastomers, certain paints and coatings and is incompatible with strong oxidizers. For critical applications, perform material compatibility testing or consult the manufacturer for recommended gaskets and seals.
What are the key technical specifications for n‑Propyl Alcohol I should check?
Key specs include CAS 71-23-8, formula C3H8O, molecular weight 60.10 g/mol, typical boiling point ≈97°C, density ≈0.80 g/mL at 20°C, flash point ≈23–25°C (closed cup) and specified purity/water content. Always confirm the exact specification sheet or COA for the batch you receive.
Which industries and applications commonly use n‑Propyl Alcohol?
Common industries include coatings and paints, adhesives, chemical manufacturing (intermediates), electronics cleaning, laboratory and analytical use, and specialty chemicals. It is used as a solvent, processing aid, and reactant in organic syntheses.
How can I purchase n‑Propyl Alcohol and what availability/lead times should I expect?
n‑Propyl alcohol is widely available from chemical suppliers in multiple grades and packaging sizes; samples are often available on request and bulk orders typically have short lead times. Lead time and minimum order quantity depend on grade, packaging and geographic location, so contact your supplier for current availability and pricing.
