What Does Propylene Mean?

Propylene is a gas that is an organic compound and has no color. It is a hydrocarbon, flammable and is often used as fuel. Most propylene is extracted during a petroleum refining process. Propylene has the molecular formula of C3H6 and its molecular weight is 42.08 g/mol.

Propylene may also be known as propyne.


Corrosionpedia Explains Propylene

Although propylene is a gas, it is normally shipped as a liquid. Propylene is transformed into its liquid phase not by a reduction in temperature, but by an increase in pressure. This allows more propylene to be stored in a container within the same volume.

Propylene is very similar to propane, which is also shipped in its liquid form. Both fuel gases put out similar BTU's and have an odor, although propylene has a natural odor and propane uses an additive to create its smell. Propane and propylene differ in their combustion characteristics as well. Propylene has a double bond in its individual molecules, which leads to a hotter combustion than propane.

Propylene is also used to make polymers such as polypropylene, which is used for automotive components, furniture, shipping products and storage tanks. Propylene can also be used as a refrigerant.
