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.
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.
n.
A hypothetical radical, CH3O, analogous to hydroxyl.
n.
A binary compound of methyl with some element; as, aluminium methide, Al2(CH3)6.
a.
Of, pertaining to, or designating, any one of a series of acids regarded as acid ethereal salts of hyposulphurous acid; as, methyl sulphinic acid, CH3.SO.OH, a thick unstable liquid.
n.
Any one of a series of basic compounds which consist essentially of sulphur united with hydrocarbon radicals. In general they are oily or crystalline deliquescent substances having a peculiar odor; as, trimethyl sulphine, (CH3)3S.OH. Cf. Sulphonium.
a.
Pertaining to, or designating, one of three metameric acids, CH3.C6H4.CO2H, which are related to toluene and analogous to benzoic acids. They are white crystalline substances, and are called respectively orthotoluic acid, metatoluic acid, and paratoluic acid.
n.
An alcoholate of methyl alcohol in which the hydroxyl hydrogen is replaced by a metal, after the analogy of a hydrate; as, sodium methylate, CH3ONa.
n.
Any one of six metameric hydrocarbons, (CH3)2.C6H3.NH2, resembling aniline, and related to xylene. They are liquids, or easily fusible crystalline substances, of which three are derived from metaxylene, two from orthoxylene, and one from paraxylene. They are called the amido xylenes.
n.
A colorless volatile alkaline liquid, N.(CH3)3, obtained from herring brine, beet roots, etc., with a characteristic herringlike odor. It is regarded as a substituted ammonia containing three methyl groups.
n.
Alkarsin; a colorless, poisonous, arsenical liquid, As2(CH3)4, spontaneously inflammable and possessing an intensely disagreeable odor. It is the type of a series of compounds analogous to the nitrogen compounds called hydrazines.
n.
Methyl alcohol, CH3OH; -- also, by extension, any one in the homologous series of paraffine alcohols of which methyl alcohol is the type.
n.
Any one of several metameric alkaloids, C5H3N.(CH3)2, of the pyridine series, obtained from bone oil as liquids, and having peculiar pungent odors. These alkaloids are also called respectively dimethyl pyridine, ethyl pyridine, etc.
n.
A colorless, fragrant liquid, C6H3(CH3)3, of the benzene series of hydrocarbons, obtained by distilling acetone with sulphuric acid.
n.
A colorless crystalline substance, C6H3.CH3.(OH)2, which is obtained from certain lichens (Roccella, Lecanora, etc.), also from extract of aloes, and artificially from certain derivatives of toluene. It changes readily into orcein.
n.
Any one of six metameric phenol derivatives of xylene, obtained as crystalline substances, (CH3)2.C6H3.OH.
a.
Pertaining to, or designating, an acid, CH3C6H3(CO2H)2, obtained as a white crystalline substance by the partial oxidation of mesitylene; -- called also mesitic acid.
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.
n.
The hydrocarbon radical, CH3.C6H4, regarded as characteristic of certain compounds of the aromatic series related to toluene; as, tolyl carbinol.
n.
The unsymmetrical hypothetical hydrocarbon radical, CH3.CH2.CH, analogous to ethylidene, and regarded as the type of certain derivatives of propane; -- called also propylidene.
