Butanone

Butanone generally refers to methyl ethyl ketone

1. Product introduction

Methyl ethyl ketone is an organic compound with chemical formula CH3COCH2CH3 and molecular weight 72.11. It is a colorless transparent liquid with a smell 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, vapors can form explosive mixtures with air. High concentrations of steam are narcotic.

3. Product features and uses

1, used as cellulose acetate, acrylic resin, alkyd resin, paint, ink solvent, dye binder, lubricating oil dewaxing agent, vulcanization accelerator, etc

2. Used as a reagent for the determination of cadmium, copper and mercury, as a standard substance for chromatographic analysis and as a solvent for semiconductor lithography

3, GB 2760-96 is the allowable use of edible spices. Mainly used for the preparation of cheese, coffee and banana flavor. Can also be used as an extraction solvent.

4, mainly used as a solvent, such as for lubricating oil dewaxing, paint industry and a variety of resin solvents, vegetable oil extraction process and refining process of azeotropic distillation, its advantage is strong solubility, volatility is lower than acetone, is a medium boiling ketone solvent. Butanone or the preparation of medicine, dyes, detergents, spices, antioxidants and some catalysts is an intermediate, synthesis of anti-peeling agent methyl ethyl ketone oxime, polymerization catalyst methyl ethyl ketone peroxide, corrosion inhibitor methyl pentylene alcohol, in the electronic industry used as integrated circuit lithography developer.

5, is the preparation of acaricide pyrazamine raw materials.

4. Product details

Operation precautions: closed operation, full ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear a self-priming filter gas mask (half-mask), chemical safety glasses, antistatic overalls, and rubber oil-resistant gloves. Keep away from fire and heat source. No smoking in workplace. Use explosion-proof ventilation systems and equipment. Prevent steam leakage into the workplace air. Avoid contact with oxidizer, reducing agent and alkali. When filling, the flow rate should be controlled, and there is a grounding device to prevent electrostatic accumulation. Handling should be carried lightly to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Empty containers may contain hazardous materials.

5. Delivery, transportation and services

Storage precautions: Store in a cool and ventilated warehouse. Keep away from fire and heat source. The storage temperature should not exceed 30℃. Keep container sealed. It should be stored separately with oxidizer, reducing agent and alkali, and must not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that may cause sparks. The storage area shall be equipped with leakage emergency treatment equipment and suitable storage materials.

Transportation precautions: Transportation vehicles should be equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment. It is best to ship in the morning and evening in summer. The trough (tank) car used in transportation should have a grounding chain, and the groove can be equipped with a hole partition to reduce the shock generated static electricity. It is strictly forbidden to mix and transport with oxidizer, reducing agent, alkali and edible chemicals. During transportation, it should be protected from sun exposure, rain and high temperature. Stay away from fire, heat source, high temperature area. The exhaust pipe of the vehicle carrying the goods must be equipped with fire retardant device. Mechanical equipment and tools that are easy to generate sparks are prohibited to be loaded and unloaded. Road transportation should follow the prescribed route, do not stay in residential and densely populated areas. Slip away should be forbidden in railway transportation. It is strictly prohibited to transport in bulk by wooden vessel or cement vessel.

Packing notes: small opening steel drum; Ordinary wooden case outside ampoule bottle; Wooden cases outside threaded glass bottles, iron capped glass bottles, plastic bottles or metal drums (cans).
