What is 1-butanol (CAS 71-36-3)?
1-Butanol (CAS 71-36-3), with the chemical formula CH₃CH₂CH₂CH₂OH, is a colorless liquid with an alcohol-like odor. It has a boiling point of 117.7°C and is slightly soluble in water.
What is 1-butanol (CAS 71-36-3) used for?
1-Butanol (CAS 71-36-3) is a widely used solvent and chemical intermediate, with primary applications spanning solvents, chemical synthesis, pharmaceuticals and cosmetics, energy and environmental protection, and other industrial sectors. Detailed specifications are as follows:
Solvent Applications
- Paints and Inks: Dissolves urea-formaldehyde, cellulose, and alkyd resins; regulates viscosity and drying speed; improves paint film leveling; prevents whitening and pinholes. Used in nitrocellulose lacquers, amino paints, and gravure printing inks to enhance pigment dispersion and adhesion.
- Adhesives and Electronic Cleaning: 1-butanol serves as an inert diluent in urea-formaldehyde and phenolic adhesives; used for cleaning electronic components to remove grease and flux residues.
- Pharmaceuticals and Extraction: Used in antibiotic (e.g., erythromycin) and traditional Chinese medicine production to extract active ingredients like alkaloids and flavonoids, reducing impurities to meet pharmaceutical standards.
- Cosmetics: 1-Butanol is used in cosmetics such as nail polish, working with primary solvents to dissolve pigments and regulate evaporation rates, typically at an addition level of approximately 10%.
Chemical Intermediates
- Plasticizer Synthesis: 1-butanol reacts with phthalic anhydride to form dibutyl phthalate (DBP), used as a plasticizer in PVC products; also synthesizes environmentally friendly plasticizers like dibutyl adipate.
- Esters and Fine Chemicals: Produces butyl acetate (solvent for coatings/inks) and butyl lactate (solvent for food/pharmaceuticals); oxidizes to form n-butyraldehyde and butyric acid (food preservatives/flavorings); used in preparing n-butylamine and surfactants (detergents/emulsifiers).
Energy and Environmental Protection
- Biofuels and Additives: Bio-based n-butanol serves as a gasoline substitute or additive, offering higher energy density than ethanol, low corrosivity, and excellent miscibility with gasoline; improves diesel cetane number while reducing particulate matter and nitrogen oxide emissions.
- Environmental Processes: 1-Butanol used in solvent recovery for extraction separation and wastewater treatment, reducing VOC emissions.
Other Industrial Applications
- Flavors & Food: 1-Butanol extends fragrance longevity as a fixative; used in flavor formulations for baked goods, puddings, candies, etc.
- Inks & Textiles: Serves as a defoamer in screen printing; used for fabric degreasing and dye dissolution in textile industries.
- Analytical Reagents: Chromatography standard material; used as a solvent or reagent in organic synthesis
What precautions should be taken when using 1-butanol?
The use and storage of 1-butanol (CAS 71-36-3) must strictly adhere to safety protocols to prevent hazards.
Usage Precautions:
- 1-Butanol (CAS 71-36-3) is a flammable liquid with a flash point of approximately 35°C. Keep away from ignition sources and heat sources (e.g., alcohol lamps, heaters) during use. Never operate near open flames.
- Ensure the work area is well-ventilated to prevent vapor accumulation and the formation of explosive mixtures.
- Wear protective gloves, safety goggles, and a respirator to avoid direct skin contact and vapor inhalation. If contact occurs, immediately rinse with copious amounts of water.
- Do not store or use in combination with strong oxidizing agents, strong acids, or strong alkalis to prevent chemical reactions.
Storage Precautions:
- Store in a cool, dry, well-ventilated warehouse at temperatures below 30°C, away from ignition sources and heat;
- Use containers with excellent sealing properties (e.g., iron drums, plastic drums) to prevent vapor leakage;
- Equip the storage area with firefighting equipment (e.g., dry powder extinguishers, foam extinguishers). Smoking and open flames are strictly prohibited.
- Store 1-butanol (CAS 71-36-3) separately from oxidizers, acids, and alkalis. Avoid stacking under heavy pressure to prevent container damage. Implement static electricity prevention measures to avoid hazards caused by static buildup.
