Propane CAS 74-98-6
Product name: High purity propane C3H8
Other names: dimethyl methane; Propane
Product purity :99.5~99.999%
Packing description: Liquefied cylinder, special cylinder,15kg
Product Description: Colorless, odorless, flammable liquefied gas. Liquefied bottled gas at its vapor pressure (7.48 kgf/cm2 @21.1°C). Mainly used in organic synthesis, fuel, solvent, manufacture of ethylene propylene, refrigerant, standard gas, calibration gas, plasma dry engraving.
Note: Propane is a narcotic gas that has mild anesthetic and irritating effects after inhalation. People have only mild dizziness at 10% concentration, no irritation symptoms, and no effect at 1% concentration. Inhalation of higher concentrations of the mixture of propane and butane may cause dizziness, headache, excitement or drowsiness, nausea, vomiting, salivation, mild reduction in blood pressure, slow pulse, decreased nerve reflexes, and in severe cases, anesthesia and loss of consciousness. The workplace should be ventilated, especially in low-lying areas, because propane is heavier than air and easy to stay in low-lying areas and not easy to spread. Bottled gas products are high-pressure filled gas, which should be used after decompression and decompression. The packaged gas cylinder has a service life, and the expired gas cylinder must be sent to a department for safety inspection before it can continue to be used. When each bottle of gas is used to exhaust gas, the residual pressure in the bottle should be kept at 0.5MPa, and the minimum residual pressure should not be lower than 0.25MPa, and the bottle valve should be closed to ensure the quality of the gas and the safety of use. Bottled gas products in transportation, storage, use should be classified stacking, flammable gas and combustion gas stacking together, not near the open fire and heat sources, should be done not near the fire, do not touch oil wax, do not explode, do not throw, do not impact, is strictly prohibited in the cylinder arc or arc, is strictly prohibited rough loading and unloading
