Product Description:

The appearance of this product is glossy flake crystal, which is easy to sublimate at room temperature, insoluble in water, soluble in anhydrous ether, ethanol, benzene, etc. It is a flammable solid, and no fire source is allowed.

Core performance:

It is an important polycyclic aromatic hydrocarbon in industry,

Scope of application:

It can be used to produce phthalic anhydride, methylnaphthylamine, dye intermediates, 1-naphthol, 2-naphthol, camphor, plasticizers, synthetic resins, rubber additives, pesticides, etc. it is mainly used in medicine, dyes, and other industries.

Technical indicators:

Packaging and storage:

1. It is packed in inner plastic bag and outer woven bag, with the specification of 25 kg.

2. Contact with strong oxidants such as chromic anhydride, chlorate and potassium permanganate can produce strong reaction and cause combustion or explosion.

3. Store in a cool and ventilated warehouse. Keep away from fire and heat source and prevent direct sunlight. Keep the container sealed. Flammable in case of open fire and high heat. When burning, it emits toxic and irritating smoke.

4. Be careful not to encounter sharp objects during transportation to prevent broken packages from being affected by moisture. Cover with rain cloth during transportation to prevent moisture. Handle with care to keep the package intact.

5. The powder and air can form an explosive mixture. When reaching a certain concentration, it will explode in case of Mars.

Safety protection:

It has stimulating effect, and high concentration can cause hemolytic anemia and liver and kidney damage.

1. Acute poisoning: when inhaling high concentration naphthalene vapor or dust, there will be eye and respiratory tract irritation, corneal turbidity, headache, nausea, vomiting, anorexia, low back pain, frequent urination, protein and red and white cells in urine, as well as optic neuritis and retinitis. In severe cases, toxic encephalopathy and liver damage may occur. Oral poisoning mainly causes hemolysis, liver and kidney damage, and even acute renal failure and liver necrosis.

2. Chronic poisoning: repeated exposure to naphthalene gas can cause headache, fatigue, nausea, vomiting and blood system damage. It can cause cataract, optic neuritis and retinopathy. Skin contact can cause dermatitis.

3. In case of contact with eyes, lift the eyelids, immediately wash them with plenty of water or normal saline, and get medical attention in time.

4. In case of contact with the skin, take off the contaminated clothes and wash the skin thoroughly with soapy water and clear water.

5. Inhalation. Quickly leave the site to a place with fresh air and keep the respiratory tract unblocked. If breathing is difficult, give oxygen. If breathing stops, carry out artificial respiration immediately and seek medical treatment in time.

6. It is forbidden to eat.

Environmental protection:

It is strictly prohibited to flow out and dump everywhere, so as not to affect the environment.

Isolate the leakage contaminated area and restrict access. Cut off the fire source. It is recommended that emergency treatment personnel wear self-contained breathing apparatus and general work clothes. Do not touch the leakage directly. Small amount of leakage: to avoid dust, use non sparking tools to collect in dry, clean and covered containers. Transport it to an open place and detonate it. Or incinerate on site under the condition of ensuring safety. Massive leakage: cover with plastic cloth and canvas to reduce flying. Use non sparking tools to collect, recycle or transport to waste disposal sites for disposal.

Fire guidelines:

Flammable in case of open fire and high heat. When burning, it emits toxic and irritating smoke. Contact with strong oxidants such as chromic anhydride, chlorate and potassium permanganate can produce strong reaction and cause explosion or combustion. The powder and air form an explosive mixture. When it reaches a certain concentration, it will explode when it meets Mars.

Fire extinguishing agent: carbon dioxide, foggy water and sand. Do not shoot water directly into the melt, so as to avoid serious flowing fire or violent boiling splash.
