ethene vs ethylene

In applications where toxicity is NOT a concern, ethylene glycol is often the heat transfer fluid of choice. 1 0. attakkdog. The majority of ethylene is produced using a process called “steam cracking”, a thermal process where hydrocarbons are broken down, or “cracked” into smaller molecules that are then used to manufacture more useful (and valuable) chemicals. Recommendations : Air Liquide has gathered data on the compatibility of gases with materials to assist you in evaluating which materials to use for a gas system.
