Product Introduction
1-Butanol (CAS 71-36-3), commonly referred to as n-Butanol or n-Butyl alcohol, is a four-carbon straight-chain alcohol. It is a colorless liquid with a characteristic vinous, banana-like odor. As a versatile medium-boiling solvent, it bridges the gap between hydrocarbon solvents and water, offering excellent solvency for various natural and synthetic resins. It is an essential building block in the chemical industry, primarily used in the production of butyl acetate, acrylate esters, and glycol ethers, while also serving as a critical processing solvent in the pharmaceutical and textile industries.
Product Selling Points

-
Advantage: Acts as a latent solvent for nitrocellulose and a primary solvent for most resins.
-
Benefit: Superior Coating Finish: Improves the flow, gloss, and blush resistance of lacquers and enamels, ensuring a high-quality, professional finish in automotive and industrial coatings.
2. High Chemical Reactivity for Esterification
-
Advantage: Primary hydroxyl group ensures high conversion rates when reacted with organic acids.
-
Benefit: Efficient Intermediate: Serves as a reliable feedstock for producing Butyl Acetate and Butyl Acrylate, helping manufacturers achieve higher yields and lower production costs.
3. Controlled Low-Moisture Grade
-
Advantage: Our 1-Butanol is processed to maintain moisture levels below 0.1%.
-
Benefit: Process Safety: Prevents unwanted side reactions in moisture-sensitive chemical syntheses and ensures compatibility with high-performance polyurethane and epoxy systems.
Applications
Paints and Coatings
Used as a solvent for lacquers, enamels, and varnishes to improve flow and prevent “blushing” in humid conditions.
Chemical Intermediates
Primary feedstock for the production of Butyl Acetate, Butyl Acrylate, and Dibutyl Phthalate (DBP).
Pharmaceutical Industry
Serves as an extractant for antibiotics, vitamins, and hormones, and as a solvent in the purification of drugs.
Textile Auxiliaries
Used in the manufacture of coated fabrics and as a component in various textile processing chemicals.
Packaging & Storage
-
Packaging: 170kg net weight in UN-certified steel drums; 20-ton ISO Tanks.
-
Storage: Store in a cool, dry, and well-ventilated fireproof warehouse. Crucial: 1-Butanol is a flammable liquid. Keep away from heat, sparks, open flames, and strong oxidizing agents. Containers should be grounded to prevent static discharge.

FAQ
Q: Where can I find the EINECS number for 1-Butanol?
A: The EINECS number is 200-751-6, as listed in the physical properties table.
Q: What is the main difference between 1-Butanol and Isobutanol?
A: 1-Butanol is a straight-chain alcohol, while Isobutanol is branched. 1-Butanol generally has a higher boiling point and different solvency characteristics, making it more suitable for certain high-solids coating formulations.
Q: Is n-Butanol miscible with water?
A: It is only partially miscible with water (about 7.3g per 100ml at 25 C). However, it is completely miscible with most organic solvents like alcohols, ethers, and hydrocarbons.
Q: Does 1-Butanol have a strong odor?
A: Yes, it has a distinct, somewhat pungent vinous odor. Proper ventilation is required when handling the liquid in confined spaces.
