Methyl ethyl ketone is an organic compound with chemical formula CH3COCH2CH3 and molecular weight of 72.11. It is a colorless transparent liquid with an odor similar to acetone. Volatile. It can be miscible with ethanol, ether, benzene, chloroform and oil. Soluble in 4 parts of water, but the solubility decreases when the temperature rises, and can form an azeotropic mixture with water. Low toxicity, median lethal dose (rat, oral) 3300mg/kg. Flammable, vapor can form explosive mixtures with air. High concentrations of steam are narcotic.

Packing Specification
Butyl ketone packaging 160KG, large barrel using 200L iron drum, small barrel using 18L, 20L small can packaging, if you have special requirements can contact us to negotiate customization.
Method Of Storage And Transportation
Store butanone in a cool, ventilated warehouse. Stay away from fire and heat sources. The temperature in the warehouse should not exceed 30℃. Keep out of direct sunlight. Keep the container sealed. It should be stored separately from the oxidant. The lighting, ventilation and other facilities in the warehouse shall be of explosion-proof type, and the switch shall be located outside the warehouse. Equipped with the corresponding variety and quantity of fire equipment. Barrel stacking should not be too large, should leave wall distance, top distance, column distance and necessary fire inspection walkway. Fire and explosion proof technical measures should be taken during tank storage. Prohibit the use of mechanical equipment and tools that are prone to spark. When filling, attention should be paid to the flow rate (not exceeding 3m/s), and there is a grounding device to prevent static electricity accumulation. Handling should be carried lightly to prevent damage to packaging and containers.
Protective Measures
Respiratory protection: when the concentration in the air exceeds the standard, self-suction filter gas mask (half mask) should be worn. Eye protection: Wear chemical safety glasses if necessary. Body protection: wear anti-static work clothes. Hand protection: Wear latex gloves. Other: smoking is strictly prohibited in the workplace. Pay attention to personal hygiene. Avoid long-term repeated exposure.
