Specification

CAS No.:74-98-6

EINECS：200-827-9

UN:1075

Class:2.1

Formula:C3H8

Application

Propane is mainly used as fuel. It is widely used as a refrigerant in oil refining, chemical and natural gas processing operations. Used as a deasphalting solvent for lubricating oil fractions. Used as standard gas and preparation of special standard mixture.

A colorless, tasteless, flammable liquefied gas. 

Liquefied bottled gas, the pressure is its vapor pressure (7.48kgf/cm2@21.1°C). Mainly used in organic synthesis, fuel, solvent, manufacturing ethylene propylene, refrigerant, standard gas, calibration gas, plasma dry engraving.

Notes

The workplace should be ventilated, especially in low-lying areas, because propane is heavier than air and tends to stay in low-lying areas rather than diffuse. Bottled gas products for high pressure filled gas, use should be reduced pressure before use. Each gas cylinder must be sent to the department for safety inspection before it can continue to use high purity propane. When using the exhaust gas of each gas bottle, the residual pressure in the bottle should be kept at 0.5NPa, and the minimum residual pressure should not be less than 0.25WPa. The valve should be closed to ensure the quality and safety of the gas. Bottled gas products should be stacked up in classification during transportation, storage and use. It is strictly forbidden to stack combustible gas and combustion-supporting gas together, not close to open fire and heat source, not close to fire, not contaminated with oil wax, not exposed to the sunlight, not re-thrown, not hit, not arc ignition or arc on the gas cylinder, and not brutal handling.
