Phene :: Phene (n.) Benzene.

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..

Phenyl :: Phenyl (n.) A hydrocarbon radical (C6H5) regarded as the essential residue of benzene, and the basis of an immense number of aromatic derivatives..

Para- :: Para- () A prefix denoting: (a) Likeness, similarity, or connection, or that the substance resembles, but is distinct from, that to the name of which it is prefixed; as paraldehyde, paraconine, etc.; also, an isomeric modification. (b) Specifically: (Organ. Chem.) That two groups or radicals substituted in the benzene nucleus are opposite, or in the respective positions 1 and 4; 2 and 5; or 3 and 6, as paraxylene; paroxybenzoic acid. Cf. Ortho-, and Meta-. Also used adjectively..

Nitrobenzene :: Nitrobenzene (n.) A yellow aromatic liquid (C6H5.NO2), produced by the action of nitric acid on benzene, and called from its odor imitation oil of bitter almonds, or essence of mirbane. It is used in perfumery, and is manufactured in large quantities in the preparation of aniline. Fornerly called also nitrobenzol..

Nitrobenzole :: Nitrobenzole (n.) See Nitrobenzene.

Diazo- :: Diazo- () A combining form (also used adjectively), meaning pertaining to, or derived from, a series of compounds containing a radical of two nitrogen atoms, united usually to an aromatic radical; as, diazo-benzene, C6H5.N2.OH..

Azobenzene :: Azobenzene (n.) A substance (C6H5.N2.C6H5) derived from nitrobenzene, forming orange red crystals which are easily fusible..

Benzene :: Benzene (n.) A volatile, very inflammable liquid, C6H6, contained in the naphtha produced by the destructive distillation of coal, from which it is separated by fractional distillation. The name is sometimes applied also to the impure commercial product or benzole, and also, but rarely, to a similar mixed product of petroleum..

Sulphonium :: Sulphonic (a.) Pertaining to, or derived from, a sulphone; -- used specifically to designate any one of a series of acids (regarded as acid ethereal salts of sulphurous acid) obtained by the oxidation of the mercaptans, or by treating sulphuric acid with certain aromatic bases (as benzene); as, phenyl sulphonic acid, C6H5.SO2.OH, a stable colorless crystalline substance..

Styrone :: Styrolene (n.) An unsaturated hydrocarbon, C8H8, obtained by the distillation of storax, by the decomposition of cinnamic acid, and by the condensation of acetylene, as a fragrant, aromatic, mobile liquid; -- called also phenyl ethylene, vinyl benzene, styrol, styrene, and cinnamene..

Azo- :: Azo- () Now especially applied to compounds containing a two atom nitrogen group uniting two hydrocarbon radicals, as in azobenzene, azobenzoic, etc. These compounds furnish many artificial dyes. See Diazo-..

Chloranil :: Chloranil (n.) A yellow crystalline substance, C6Cl4.O2, regarded as a derivative of quinone, obtained by the action of chlorine on certain benzene derivatives, as aniline..

Toluene :: Toluene (n.) A hydrocarbon, C6H5.CH3, of the aromatic series, homologous with benzene, and obtained as a light mobile colorless liquid, by distilling tolu balsam, coal tar, etc.; -- called also methyl benzene, phenyl methane, etc..

Bond :: Bond (n.) A unit of chemical attraction; as, oxygen has two bonds of affinity. It is often represented in graphic formulae by a short line or dash. See Diagram of Benzene nucleus, and Valence..

Tetrol :: Tetrol (n.) A hypothetical hydrocarbon, C4H4, analogous to benzene; -- so called from the four carbon atoms in the molecule..

Met- :: Met- () That two replacing radicals, in the benzene nucleus, occupy the relative positions of 1 and 3, 2 and 4, 3 and 5, 4 and 6, 5 and 1, or 6 and 2; as, metacresol, etc. See Ortho-, and Para-..

Thioxene :: Thioxene (n.) Any one of three possible metameric substances, which are dimethyl derivatives of thiophene, like the xylenes from benzene..

Phenylene :: Phenylene (n.) A hypothetic radical (C6H4) occurring in certain derivatives of benzene; as, phenylene diamine..
