How Is Ethylene Made? | Our Pastimes

Ethylene is a hydrocarbon, a flammable and colorless alkene which is found in gaseous form. Ethylene is obtained from petroleum during the refining process. It can also be synthesized from natural gas and is a byproduct of the refining process. Ethylene is used in the manufacture of several chemicals and is also often used as an anesthetic.
