“There are similarities between propylene glycol and ethylene glycol, the anti-freeze used in automobiles,” Dale said.
The idea held up to about 1890 was that the illuminating value depended upon the amount of ethylene present.
This converts the alcohol into a gas known as ethylene (C2H4).
Propylene oxide is less toxic than ethylene oxide but is still highly toxic.
Acetylene combines with hydrogen in the presence of platinum black, and ethylene and then ethane result.
Dichloride of ethylene is detected by shaking up the chloroform with dry potassic carbonate, and then adding metallic potassium.
A similar relation holds good between marsh gas and olefiant gas (ethylene).
ethylene ripening of tomatoes in relation to stage of maturity.
ethylene burns with a bright luminous flame, and forms a very explosive mixture with oxygen.
A drawback particularly associated with ethylene 45 oxide is its tendency to polymerize during storage.
ethylene eth·yl·ene (ěth'ə-lēn')
An explosive gas derived from natural gas and petroleum infrequently used as an inhalation anesthetic. Also called ethene.
The bivalent hydrocarbon radical C2H4 that is isomeric to the ethylidene radical.
A colorless, flammable gas that occurs naturally in certain plants and can be obtained from petroleum and natural gas. As a plant hormone, it ripens and colors fruit, and it is manufactured for use in agriculture to speed these processes. It is also used as a fuel and in making plastics. Ethylene is the simplest alkene, consisting of two carbon atoms joined by a double bond and each attached to two hydrogen atoms. Also called ethene. Chemical formula: C2H4.
