Cyclohexanone, an organic compound, is a saturated cyclic ketone whose carbonyl carbon atoms are contained in a six-membered ring. Colorless transparent liquid with earthy flavor, and mint flavor when it contains traces of phenol. The impurity is light yellow, which develops color as impurities are generated during storage time, from water white to grayish yellow, with a strong pungent odor. The explosive pole mixed with air is the same as the open chain saturated ketone. There is insufficient evidence of carcinogenicity of cyclohexanone. It is mainly used as a raw material and solvent for organic synthesis in industry. For example, it can dissolve nitrocellulose, paints, and paints.
Function and purpose
Cyclohexanone is an important chemical raw material and the main intermediate for the manufacture of nylon, caprolactam and adipic acid. It is also an important industrial solvent, such as paint, especially those containing nitrocellulose, vinyl chloride polymer and its copolymer or methacrylate polymer paint. It is an excellent solvent for organophosphorus pesticides and many similar pesticides, as a solvent for dyes, as a viscous solvent for piston-type aviation lubricants, and as a solvent for grease, wax and rubber. It is also used as a leveling agent for dyeing and fading silk, a degreasing agent for polishing metal, and wood coloring and painting. Cyclohexanone can be used to remove film, stain and spot. Cyclohexanone and cyanoacetic acid are condensed to obtain cyclohexylidene cyanoacetic acid, which is eliminated and decarboxylated to obtain cyclohexene acetonitrile, and finally cyclohexene ethylamine is obtained by hydrogenation [3399-73-3]. Cyclohexene ethylamine is a drug Intermediates of Kemeiqie, Temaren, etc. Used as a high boiling point solvent for nail polish and other cosmetics. Usually mixed with low boiling point solvents and medium boiling point solvents to obtain suitable volatilization speed and viscosity.
Storage and transportation method
Transportation precautions: The transportation vehicles should be equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment during transportation. It is best to transport sooner or later in summer. The tank (tank) truck used during transportation should have a grounding chain, and a hole partition can be set in the tank to reduce vibration and static electricity. Mixed shipment and transportation with oxidants, reducing agents, edible chemicals, etc. is strictly prohibited. Avoid exposure to the sun, rain, and high temperature during transportation. Stay away from fire, heat sources, and high-temperature areas during stopovers. The exhaust pipe of the vehicle carrying the item must be equipped with a fire arrester, and it is prohibited to use mechanical equipment and tools that are prone to sparks for loading and unloading. When transporting by road, follow the prescribed route and do not stop in residential or densely populated areas. It is forbidden to drop off during railway transportation. It is strictly forbidden to transport in bulk by wooden or cement ships;
Precautions for storage: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30°C. Keep the container tightly closed. It should be stored separately from oxidants and reducing agents, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials;
Packaging precautions: ordinary wooden box outside the ampoule; screw-top glass bottle, iron-capped glass bottle, plastic bottle or Metal barrels (cans) outside ordinary wooden boxes; threaded glass bottles, plastic bottles or tin-plated steel drums (cans) outside full floor grid boxes, fiberboard boxes or plywood boxes.
Dangerous goods transport number UN 1915
Notes
Dangerous
Health hazards: The product has anesthetic and stimulating effects. Acute poisoning: The main manifestations are eye, nose, and throat mucosal irritation, dizziness, chest tightness, and general weakness. In severe cases, shock, coma, convulsions of the limbs, pulmonary edema, and death due to respiratory failure may occur. It can return to normal sooner after disengagement. The liquid is irritating to the skin; eye contact may cause corneal damage. Chronic effects: Long-term repeated exposure can cause dermatitis.
Explosion hazard: The product is flammable and irritating.
First aid measures
Skin contact: Take off contaminated clothing and wash skin thoroughly with soap and water.
Eye contact: Lift the eyelid immediately, and rinse thoroughly with plenty of running water or normal saline for at least 15 minutes. Seek medical attention.
Inhalation: quickly leave the scene to a place with fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.
Ingestion: Drink enough warm water to induce vomiting and seek medical attention.
Fire-fighting measures
Hazardous combustion products: carbon monoxide, carbon dioxide.
Fire fighting method: spray water to cool the container, and if possible, move the container from the fire scene to an open place.
Extinguishing agent: foam, dry powder, carbon dioxide, sand.
Leakage emergency response
Emergency treatment: Quickly evacuate personnel from the contaminated area to a safe area, isolate them, and strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure respirators and anti-static overalls. Cut off the source of leakage as much as possible. Prevent entry into restricted spaces such as sewers and flood drains.
Small leakage: Use sand or other non-combustible materials to absorb or absorb. It can also be washed with a large amount of water, and the washing water is diluted and put into the waste water system.
A large number of leaks: build a dike or dig a pit for storage. Cover with foam to reduce steam hazards. Use explosion-proof pump to transfer to tank truck or special collector, recycle or transport to waste disposal site for disposal.
Operational disposal
Operation precautions: Airtight operation, pay attention to ventilation. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter respirators (half-face masks), chemical safety glasses, anti-static overalls, and rubber oil-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent the vapor from leaking into the air in the workplace. Avoid contact with oxidants and reducing agents. The flow rate of the filling should be controlled to prevent the accumulation of static electricity. When handling, load and unload with care to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.
Precautions for storage: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30°C. Keep the container tightly closed. It should be stored separately from oxidants and reducing agents, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities.
