Naphthene is a simple polycyclic aromatic hydrocarbon, commonly known as benzene, with a molecular formula of C10H8. It is formed by the condensation of two adjacent carbon atoms shared by two benzene rings. Colorless, toxic, easily sublimated, and has a special odor in the form of flake crystals. It is produced in large quantities from coal tar, a by-product of coking, and petroleum distillation, and is mainly used to synthesize phthalic anhydride, etc. Below, the refined naphthalene manufacturer will discuss the safe storage and transportation of naphthalene.
Precautions for handling naphthalene:
Closed operation, local ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear filter type gas mask (half mask), chemical safety goggles, anti poison penetration work clothes and anti chemical gloves. Keep away from sparks and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid generating dust. Avoid contact with oxidants. Operate and dispose of in nitrogen gas. When transporting, it is necessary to load and unload gently to prevent damage to the packaging and containers. Equip corresponding types and quantities of firefighting equipment and emergency response equipment for leaks. Empty containers may have residual harmful substances.
Precautions for storage of naphthalene:
Store in a cool and ventilated warehouse. Keep away from sparks and heat sources. The temperature of the warehouse shall not exceed 32 ℃, and the relative humidity shall not exceed 80%. Packaging sealing. It should be stored separately from oxidants and should not be mixed for storage. Equip corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with suitable materials to contain leaks.
Precautions for transportation of naphthalene:
Packaging method: Two layers of plastic bags or one layer of plastic bags with outer gunny bags, plastic woven bags, or latex cloth bags; Composite plastic woven bags (polypropylene three in one bag, polyethylene three in one bag, polypropylene two in one bag, polyethylene two in one bag); Ordinary wooden boxes with plastic bags or two-layer kraft paper bags; Thread mouth glass bottles, iron cap pressure mouth glass bottles, plastic bottles or ordinary wooden boxes outside metal barrels (cans); A threaded glass bottle, plastic bottle, or tinned thin steel plate barrel (can) with a bottom plate full of checkered boxes, fiberboard boxes, or plywood boxes; Plastic bottles, two-layer plastic bags, or two-layer kraft paper bags (with plastic bags inside or outside) with corrugated cardboard boxes.
matters needing attention
For railway transportation, naphthalene cakes loaded and unloaded on dedicated lines can be transported in bulk using enterprise owned vehicles. During transportation, transportation vehicles should be equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency response equipment. The exhaust pipe of the vehicle transporting this product must have a flame retardant device. During transportation, it is necessary to ensure that the container does not leak, collapse, fall, or be damaged. It is strictly prohibited to mix and transport with oxidants, edible chemicals, etc. During transportation, it is necessary to prevent exposure to sunlight, rain, and high temperatures. During a stopover, stay away from sparks and heat sources. The vehicle should be thoroughly cleaned after transportation. It is prohibited to slide during railway transportation.
