Methoxyl
(Meth*ox"yl) n. [Methyl + hydroxyl.] (Chem.) A hypothetical radical, CH3O, analogous to
hydroxyl.
Methyl
(Meth"yl) n. [See Methylene.] (Chem.) 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. [Formerly written also methule, methyle, etc.]
Methyl alcohol (Chem.),
a light, volatile, inflammable liquid, CH3.OH, obtained by the distillation of
wood, and hence called wood spirit; — called also methol, carbinol, etc. — Methyl amine (Chem.),
a colorless, inflammable, alkaline gas, CH3.NH2, having an ammoniacal, fishy odor. It is produced artificially,
and also occurs naturally in herring brine and other fishy products. It is regarded as ammonia in which
a third of its hydrogen is replaced by methyl, and is a type of the class of substituted ammonias. —
Methyl ether (Chem.), a light, volatile ether CH3.O.CH3, obtained by the etherification of methyl
alcohol; — called also methyl oxide. — Methyl green. (Chem.) See under Green, n. — Methyl
orange. (Chem.) See Helianthin. — Methyl violet (Chem.), an artificial dye, consisting of certain
methyl halogen derivatives of rosaniline.
Methylal
(Meth"yl*al) n. [Methylene + alcohol.] (Chem.) A light, volatile liquid, H2C(OCH3)2, regarded
as a complex ether, and having a pleasant ethereal odor. It is obtained by the partial oxidation of methyl
alcohol. Called also formal.
Methylamine
(Meth`yl*am"ine) n. (Chem.) See Methyl amine, under Methyl.
Methylate
(Meth"yl*ate) n. [Methyl + alcoholate.] (Chem.) 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.
Methylate
(Meth"yl*ate) v. t. To impregnate or mix with methyl or methyl alcohol.
