Propylene (C3H6)
DESCRIPTION (Propylene):
Propylene is a colorless, flammable gas, at atmospheric pressure and normal temperature. It is readily soluble in
alcohol and ether, and slightly soluble in water. It is one of a group of liquefied petroleum gases. It is shipped as a liquefied gas in low pressure
steel cylinders under it's own vapor pressure of approximately 136 psig @ 70° F.
