METHYL

Meth "yl, n. Etym: [See Methylene. ] (Chem. )

 

Defn: 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. Etym: [Methylene + alcohol. ] (Chem. )

 

Defn: 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

METHYLAMINE Meth `yl *am "ine ( or ), n. (Chem. )

 

Defn: See Methyl amine, under Methyl.

 

METHYLATE

Meth "yl *ate, n. Etym: [Methyl + alcoholate. ] (Chem. )

 

Defn: 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

METHYLATE Meth "yl *ate, v. t.

 

Defn: To impregnate or mix with methyl or methyl alcohol.

 

METHYLATED

METHYLATED Meth "yl *a `ted, a. (Chem. )

 

Defn: Impregnated with, or containing, methyl alcohol or wood spirit; as, methylated spirits.

 

METHYLENE

Meth "yl *ene, n. Etym: [F. méthylène, from Gr. wood spirit. ] (Chem. )

 

Defn: A hydrocarbon radical, CH2, not known in the free state, but regarded as an essential residue and component of certain derivatives of methane; as, methylene bromide, CH2Br2; -- formerly called also methene. Methylene blue (Chem. ), an artificial dyestuff consisting of a complex sulphur derivative of diphenyl amine; -- called also pure blue.

 

METHYLIC

METHYLIC Me *thyl "ic, a. (Chem. )
