Ethene :: Ethene (n.) Ethylene; olefiant gas.

Oxamide :: Oxamide (n) A white crystalline neutral substance (C2O2(NH2)2) obtained by treating ethyl oxalate with ammonia. It is the acid amide of oxalic acid. Formerly called also oxalamide.

Glycol :: Glycol (n.) A thick, colorless liquid, C2H4(OH)2, of a sweetish taste, produced artificially from certain ethylene compounds. It is a diacid alcohol, intermediate between ordinary ethyl alcohol and glycerin..

Triethylamine :: Triethylamine (n.) A tertiary amine analogous to trimethylamine.

Trimethyl :: Trimethyl () A prefix or combining form (also used adjectively) indicating the presence of three methyl groups.

Neurine :: Neurine (n.) A poisonous organic base (a ptomaine) formed in the decomposition of protagon with boiling baryta water, and in the putrefraction of proteid matter. It was for a long time considered identical with choline, a crystalline body originally obtained from bile. Chemically, however, choline is oxyethyl-trimethyl-ammonium hydroxide, while neurine is vinyl-trimethyl-ammonium hydroxide..

Methyl :: Methyl (n.) A hydrocarbon radical, CH3, not existing alone but regarded as an essential residue of methane, and appearing as a component part of many derivatives; as, methyl alcohol, methyl ether, methyl amine, etc..

Etherol :: Etherol (n.) An oily hydrocarbon regarded as a polymeric variety of ethylene, produced with etherin..

Oxide :: Oxide (n.) A binary compound of oxygen with an atom or radical, or a compound which is regarded as binary; as, iron oxide, ethyl oxide, nitrogen oxide, etc..

Xylene :: Xylene (n.) Any of a group of three metameric hydrocarbons of the aromatic series, found in coal and wood tar, and so named because found in crude wood spirit. They are colorless, oily, inflammable liquids, C6H4.(CH3)2, being dimethyl benzenes, and are called respectively orthoxylene, metaxylene, and paraxylene. Called also xylol..
