A hydrocarbon radical, CH2.(CO)2, from malonic acid.

A complex nitrogenous hydrocarbon obtained artificially (as by the action of cyanogen chloride on aniline) as a white, crystalline substance; -- called also diphenyl guanidin.

An unsaturated hydrocarbon, C30H60, of the ethylene series, obtained from beeswax as a white, scaly, crystalline wax; -- called also melissene, and melissylene.

A colorless liquid hydrocarbon resembling oil of turpentine, obtained by dehydrating menthol. It has an agreeable odor and a cooling taste.

A colorless, fragrant liquid, C6H3(CH3)3, of the benzene series of hydrocarbons, obtained by distilling acetone with sulphuric acid. -- Me*sit`y*len"ic, a.

combining form denoting in the middle, intermediate; specif. (Chem.), denoting a type of hydrocarbons which are regarded as methenyl derivatives. Also used adjectively.

A light, colorless, gaseous, inflammable hydrocarbon, CH4; marsh gas. See Marsh gas, under Gas. Methane series (Chem.), a series of saturated hydrocarbons, of which methane is the first member and type, and (because of their general chemical inertness and indifference) called also the paraffin (little affinity) series.…

The hypothetical hydrocarbon radical CH, regarded as an essential residue of certain organic compounds.

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…

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; -- c…

The complex mixture of volatile, liquid, inflammable hydrocarbons, occurring naturally, and usually called crude petroleum, mineral oil, or rock oil. Specifically: That portion of the distillate obtained in the refinement of petroleum which is intermediate between the lighter gasoline and the heavier benzine, and has a…

A white crystalline aromatic hydrocarbon, C10H8, analogous to benzene, and obtained by the distillation of certain bituminous materials, such as the heavy oil of coal tar. It is the type and basis of a large number of derivatives among organic compounds. Formerly called also naphthaline. Naphthalene red (Chem.), a dyes…

A hydrocarbon radical regarded as the essential residue of naphthalene.

ng new, recent, late; and in chemistry designating specifically that variety of metameric hydrocarbons which, when the name was applied, had been recently classified, and in which at least one carbon atom in connected directly with four other carbon atoms; -- contrasted with normal and iso-; as, neopentane; the neopara…

Any one of a series of hydrocarbons containing the nitro and the nitroso or isonitroso group united to the same carbon atom.

One of a group of metameric hydrocarbons C9H20 of the paraffin series; -- so called because of the nine carbon atoms in the molecule. Normal nonane is a colorless volatile liquid, an ingredient of ordinary kerosene.

A hydrocarbon of the paraffin series, a white waxy substance, C19H40; -- so called from the number of carbon atoms in the molecule.

Any one of several metameric unsaturated hydrocarbons (C9H14) of the valylene series.

The hydrocarbon radical, C9H19, derived from nonane and forming many compounds. Used also adjectively; as, nonyl alcohol.
