ethene
Noun: 1. A flammable, colorless, gaseous hydrocarbon (alkene): A simple organic compound consisting of two carbon atoms connected by a double bond and four hydrogen atoms (C₂H₄). It is a fundamental building block in the petrochemical industry.
Ethene is a primary industrial chemical. It is not typically used in everyday conversation but is a standard term in chemistry, engineering, and manufacturing contexts. * As a raw material: Ethene is used to manufacture numerous other chemicals and plastics. * In scientific description: Ethene is described by its physical properties (gas, flammable) and chemical structure (alkene).
- Industrial Process: "The cracker plant produces ethene from natural gas liquids."
- Chemical Property: "The double bond in ethene makes it highly reactive."
- End Use: "Polymerizing ethene yields polyethylene, a common plastic."
- As an anesthetic: In historical medical contexts, ethene was sometimes used for its anesthetic properties, though it has been replaced by safer, modern agents.
- Example: "In the early 20th century, ethene saw limited use as an inhalation anesthetic."
- Ethylene: This is a synonym for ethene and is the more common name used in industrial and commercial settings. The terms are often used interchangeably.
- Example: "The ethylene glycol in antifreeze is derived from ethene."
- Alkene: The class of unsaturated hydrocarbons to which ethene belongs, characterized by having at least one carbon-carbon double bond.
- Ethylene
- Olefiant gas (archaic term)
The word "ethene" has a single, specific meaning in scientific and industrial English, referring exclusively to the chemical compound C₂H₄. It does not have common idiomatic or figurative uses.
-
a flammable colorless gaseous alkene; obtained from petroleum and natural gas and used in manufacturing many other chemicals; sometimes used as an anesthetic
