N-butanol is an organic compound with the molecular formula C4H10O. It is a colorless and transparent liquid that emits a strong flame when burned. It has a similar odor to fusel oil, and its vapor is irritating and can cause coughing. Boiling point 117.7 ℃, relative density 0.810. 63% n-butanol and 37% water form an azeotrope. Can be miscible with ethanol, ether, and many other organic solvents. Obtained by fermentation of sugars or catalytic hydrogenation of n-butanal or butenal. Used as a solvent for fats, waxes, resins, cordyceps, varnishes, etc., or in the manufacture of paints, synthetic fibers, detergents, etc.

Safety measures

Leakage handling: a small amount of leakage is absorbed by absorbent materials; Collect a large amount of leakage with an explosion-proof pump after containment.

Hazardous characteristics: Flammable, its vapor can form explosive mixtures with air, and can cause combustion and explosion when exposed to open flames or high heat energy. Reacts violently when in contact with oxidants. In a fire scene, heated containers pose a risk of explosion.

Harmful combustion products: carbon monoxide.

Fire extinguishing

Methods: Use foam, dry powder, carbon dioxide, fog water, fire extinguishing agent and sand to extinguish the fire.  

Firefighting precautions and measures: Firefighters must wear gas masks and full body firefighting suits, and extinguish fires in the upwind direction. Try to move the container from the fire scene to an open area as much as possible. Spray water to keep the fire container cool until the fire is extinguished. If the container in the fire has changed color or produced sound from the safety relief device, it must be evacuated immediately.

Precautions for use

Operators should wear protective equipment. The maximum allowable concentration in the air within the operating area is 100mL/m3.
