Phenicine :: Phenicine (n.) A coloring matter produced by the action of a mixture of strong nitric and sulphuric acids on phenylic alcohol.

Test :: Test (n.) A reaction employed to recognize or distinguish any particular substance or constituent of a compound, as the production of some characteristic precipitate; also, the reagent employed to produce such reaction; thus, the ordinary test for sulphuric acid is the production of a white insoluble precipitate of barium sulphate by means of some soluble barium salt..

Disulphuric :: Disulphuric (a.) Applied to an acid having in each molecule two atoms of sulphur in the higher state of oxidation.

Haematoin :: Haematoin (n.) A substance formed from the hematin of blood, by removal of the iron through the action of concentrated sulphuric acid. Two like bodies, called respectively haematoporphyrin and haematolin, are formed in a similar manner..

Exsiccator :: Exsiccator (n.) An apparatus for drying substances or preserving them from moisture; a desiccator; also, less frequently, an agent employed to absorb moisture, as calcium chloride, or concentrated sulphuric acid..

Thermotype :: Thermotype (n.) A picture (as of a slice of wood) obtained by first wetting the object slightly with hydrochloric or dilute sulphuric acid, then taking an impression with a press, and next strongly heating this impression..

Monte-acid :: Monte-acid (n.) An acid elevator, as a tube through which acid is forced to some height in a sulphuric acid manufactory..

Vitriolated :: Vitriolated (a.) Changed into a vitriol or a sulphate, or subjected to the action of sulphuric acid or of a sulphate; as, vitriolated potash, i. e., potassium sulphate..

Nitroglycerin :: Nitroglycerin (n.) A liquid appearing like a heavy oil, colorless or yellowish, and consisting of a mixture of several glycerin salts of nitric acid, and hence more properly called glycerin nitrate. It is made by the action of nitric acid on glycerin in the presence of sulphuric acid. It is extremely unstable and terribly explosive. A very dilute solution is used in medicine as a neurotic under the name of glonion..

Sulphamide :: Sulphamic (a.) Of or pertaining to a sulphamide; derived from, or related to, a sulphamide; specifically, designating an amido acid derivative, NH2.SO2.OH, of sulphuric acid (analogous to sulphonic acid) which is not known in the free state, but is known in its salts..

Platinum :: Platinum (n.) A metallic element, intermediate in value between silver and gold, occurring native or alloyed with other metals, also as the platinum arsenide (sperrylite). It is heavy tin-white metal which is ductile and malleable, but very infusible, and characterized by its resistance to strong chemical reagents. It is used for crucibles, for stills for sulphuric acid, rarely for coin, and in the form of foil and wire for many purposes. Specific gravity 21.5. Atomic weight 194.3. Symbol Pt. Fo

Serine :: Serine (n.) A white crystalline nitrogenous substance obtained by the action of dilute sulphuric acid on silk gelatin.

Telluric :: Telluric (a.) Of or pertaining to tellurium; derived from, or resembling, tellurium; specifically, designating those compounds in which the element has a higher valence as contrasted with tellurous compounds; as, telluric acid, which is analogous to sulphuric acid..

Keratin :: Keratin (n.) A nitrogenous substance, or mixture of substances, containing sulphur in a loose state of combination, and forming the chemical basis of epidermal tissues, such as horn, hair, feathers, and the like. It is an insoluble substance, and, unlike elastin, is not dissolved even by gastric or pancreatic juice. By decomposition with sulphuric acid it yields leucin and tyrosin, as does albumin. Called also epidermose..

Guanidine :: Guanidine (n.) A strongly alkaline base, CN3H5, formed by the oxidation of guanin, and also obtained combined with methyl in the decomposition of creatin. Boiled with dilute sulphuric acid, it yields urea and ammonia..

Ethylene :: Ethylene (n.) A colorless, gaseous hydrocarbon, C2H4, forming an important ingredient of illuminating gas, and also obtained by the action of concentrated sulphuric acid in alcohol. It is an unsaturated compound and combines directly with chlorine and bromine to form oily liquids (Dutch liquid), -- hence called olefiant gas. Called also ethene, elayl, and formerly, bicarbureted hydrogen..

Hyposulphuric :: Hyposulphuric (a.) Pertaining to, or containing, sulphur in a lower state of oxidation than in the sulphuric compounds; as, hyposulphuric acid..

Arabinose :: Arabinose (n.) A sugar of the composition C5H10O5, obtained from cherry gum by boiling it with dilute sulphuric acid..

Carboy :: Carboy (n.) A large, globular glass bottle, esp. one of green glass, inclosed in basket work or in a box, for protection; -- used commonly for carrying corrosive liquids; as sulphuric acid, etc..

Oenothionic :: Oenothionic (a.) Pertaining to an acid now called sulphovinic, / ethyl sulphuric, acid..
