- Methyl - 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.
- Methylal - n. - 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 - n. - See Methyl amine, under Methyl.
- Methylate - 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.

- Methylated - a. - Impregnated with, or containing, methyl alcohol or wood spirit; as, methylated spirits.
- Methylene - n. - 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.
- Methylic - a. - Pertaining to, derived from, or containing, methyl; specifically, designating methyl alcohol. See under Methyl.
- Ketol - n. - One of a series of series of complex nitrogenous substances, represented by methyl ketol and related to indol.
- Methol - n. - The technical name of methyl alcohol or wood spirit; also, by extension, the class name of any of the series of alcohols of the methane series of which methol proper is the type. See Methyl alcohol, under Methyl.
- Orthoxylene - n. - That variety of xylene in which the two methyl groups are in the ortho position; a colorless, liquid, combustible hydrocarbon resembling benzene.
- Trimethylamine - 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.
- Tiglic - a. - Of, pertaining to, or designating, an acid, C4H7CO2H (called also methyl crotonic acid), homologous with crotonic acid, and obtained from croton oil (from Croton Tiglium) as a white crystalline substance.

- Sulphinic - 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.
- Metameric - a. - Having the same elements united in the same proportion by weight, and with the same molecular weight, but possessing a different structure and different properties; as, methyl ether and ethyl alcohol are metameric compounds. See Isomeric.
- Chlormethane - n. - A colorless gas, CH3Cl, of a sweet odor, easily condensed to a liquid; -- called also methyl chloride.
- Methylal - n. - 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.
- Trimethyl - - A prefix or combining form (also used adjectively) indicating the presence of three methyl groups.

- Isomeric - a. - Having the same percentage composition; -- said of two or more different substances which contain the same ingredients in the same proportions by weight, often used with with. Specif.: (a) Polymeric; i. e., having the same elements united in the same proportion by weight, but with different molecular weights; as, acetylene and benzine are isomeric (polymeric) with each other in this sense. See Polymeric. (b) Metameric; i. e., having the same elements united in the same proportions by weight, and with the same molecular weight, but which a different structure or arrangement of the ultimate parts; as, ethyl alcohol and methyl ether are isomeric (metameric) with each other in this sense. See Metameric.
- Substituted - a. - Containing substitutions or replacements; having been subjected to the process of substitution, or having some of its parts replaced; as, alcohol is a substituted water; methyl amine is a substituted ammonia.
