Overview
n-Hexane is a hydrocarbon solvent derived from petroleum, primarily composed of six carbon atoms. It is widely used in industrial applications due to its excellent solvency and low boiling point. Commonly employed in extraction processes, it is favored in industries such as pharmaceuticals, food processing, and adhesives manufacturing. Its volatility and non-polar nature make it ideal for dissolving oils, fats, and waxes. However, its flammability and toxicity necessitate careful handling and storage.
Physical and Chemical Properties
n-Hexane is a colorless, volatile liquid with a faint petroleum-like odor. It has a low density and viscosity, making it easy to handle and mix with other solvents. Its boiling point of 69°C allows for quick evaporation, which is advantageous in industrial processes requiring fast drying. The solvent is highly flammable, with a flash point of -22°C, and forms explosive mixtures with air. It is insoluble in water but miscible with most organic solvents. These properties make it a versatile but hazardous compound.
Main Applications
n-Hexane is predominantly used as a solvent in the extraction of vegetable oils from seeds and nuts. It is also employed in the production of adhesives, coatings, and rubber cement due to its ability to dissolve various polymers and resins. In laboratories, it serves as a non-polar solvent for chromatography and chemical synthesis. Additionally, it is used in the cleaning and degreasing of metal parts and electronic components.
Safety and Storage
Due to its high flammability, n-Hexane must be stored in tightly sealed containers away from heat sources and open flames. Proper ventilation is essential to prevent the accumulation of vapors, which can be explosive. Exposure to n-Hexane can cause dizziness, nausea, and long-term nerve damage. Personal protective equipment (PPE) such as gloves and respirators should be used when handling this solvent. Spills should be cleaned up immediately using absorbent materials.
B2B Procurement Guide
When procuring n-Hexane, buyers should verify the purity grade required for their specific application. Industrial-grade hexane is suitable for most uses, while higher purity grades are needed for laboratory and pharmaceutical applications. Suppliers should provide Material Safety Data Sheets (MSDS) and ensure proper labeling and packaging. Bulk purchases often come in drums or tanker trucks, while smaller quantities are available in cans or bottles. Prices vary based on market conditions and order volume.
