Product Name: Chemical Grade propylene  
Trade Mark: Sanren Brand  
Alternative Name: ?  
Molecular formula/Structural Formula:
Production Process: Using straight-run kerosene and diesel distillates,naphtha and hydrogenated tailings as raw material,the product is produced in a pipe cracking heater and obtained through cryogenic separation.  
Properties: Propylene is a colourless inflammable and explosive gas with active chemical properties. When mixed with air, it could be an explosive with the explosive limits between 2.0-11.1 Vol.%, flash point ?08℃,spontaneous ignition point 455℃. Its density is slightly higher than that of air. It is easy to disperse. The critical temperature is 91.4℃ and the critical pressure 4600kPa.

Storage: Spherical tank  
Transportation: Pipe transfer, or by means of a special vessel and special tank truck.  
Safety Precautions: 1.Propylene is an inflammable and explosive substance. During storage and transportation, safety precautions against fire and explosion must be taken. At the same time, keep away from fire, heat sources and sunlight.
2.Special tank truck must be used for transportation. In compliance with the relevant Government Ordinance concerning hazardous chemicals, due formalities must be gone through for the permission of transportation. Static electricity discharger must be provided to prevent static electricity from being accumulated. Fire fighting device must be equipped as well.
3.Propylene is anesthetic. When its concentration in the air reaches to a medium level, it could make people lose their consciousness. We should prevent ourselves from being contacted by liquefied propylene for frostbite. Guard against leakage during storage and transportation.
