Benzol :: Benzol (n.) An impure benzene, used in the arts as a solvent, and for various other purposes. See Benzene..

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..

Mirbane :: Mirbane (n.) See Nitrobenzene.

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..

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..

Hydrophlorone :: Hydrophlorone (n.) A white, crystalline benzene derivative, C8H10O2, obtained by the reduction of phlorone..

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-..

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..

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

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

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..

Phenose :: Phenose (n.) A sweet amorphous deliquescent substance obtained indirectly from benzene, and isometric with, and resembling, dextrose..

Benzine :: Benzine (n.) Same as Benzene.

Vesuvine :: Vesuvine (n.) A trade name for a brown dyestuff obtained from certain basic azo compounds of benzene; -- called also Bismarck brown, Manchester brown, etc..

Metaxylene :: Metaxylene (n.) That variety of xylene, or dimethyl benzene, in which the two methyl groups occupy the meta position with reference to each other. It is a colorless inf/ammable liquid..

Octane :: Octane (n.) Any one of a group of metametric hydrocarcons (C8H18) of the methane series. The most important is a colorless, volatile, inflammable liquid, found in petroleum, and a constituent of benzene or ligroin..

Oxybenzene :: Oxybenzene (n.) Hydroxy benzene. Same as Phenol.

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

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..

Ortho- :: Ortho- () Connection with, or affinity to, one variety of isomerism, characteristic of the benzene compounds; -- contrasted with meta- or para-; as, the ortho position; hence, designating any substance showing such isomerism; as, an ortho compound..
