Oxacid to OxYhæmacyanin
(Ox`ac"id) n. (Chem.) See Oxyacid.
(Ox"a*lan) n. [From Alloxan, by transposition of letters.] (Chem.) A complex nitrogenous substance
C3N3H5O3 obtained from alloxan as a stable white crystalline powder; called also oxaluramide.
(Ox`a*lan"tin) n. [From Alloxantin, by transposition of letters.] (Chem.) A white crystalline
nitrogenous substance (C6H4N4O5) obtained by the reduction of parabanic acid; called also leucoturic
(Ox"a*late) n. [Cf. F. oxalate. See Oxalic.] (Chem.) A salt of oxalic acid.
(Ox*al"de*hyde) n. [Oxalic + aldehyde.] (Chem.) Same as Glyoxal.
(Ox`al*eth"yl*ine) n. [Oxalic + ethyl + -ine.] A poisonous nitrogenous base (C6H10N2)
obtained indirectly from oxamide as a thick transparent oil which has a strong narcotic odor, and a physiological
action resembling that of atropine. It is probably related to pyridine.
Oxalic acid (Chem.), a dibasic acid, existing combined in oxalis as an acid potassium oxalate, and
in many plant tissues as the calcium oxalate. It is prepared on a large scale, by the action of fused
caustic soda or potash on sawdust, as a white crystalline substance, which has a strong acid taste, and
is poisonous in large doses. It is used in dyeing, calico printing, bleaching flax and straw, the preparation
of formic acid, and in salts of lemon for removing ink stains, mold, etc.
(Ox*al"ic) a. [From Oxalis: cf. F. oxalique.] (Chem.) Pertaining to, derived from, or contained
in, sorrel, or oxalis; specifically, designating an acid found in, and characteristic of, oxalis, and also certain
plant of the Buckwheat family.
(Ox"a*line) n. [Glyoxal + - ine.] (Chem.) See Glyoxaline.
(Ox"a*lis) n. [L., a kind of sorrel, Gr. fr. sharp, pungent, acid.] (Bot.) A genus of plants, mostly
herbs, with acid-tasting trifoliolate or multifoliolate leaves; called also wood sorrel.
(Ox"a*lite) n. (Min.) A yellow mineral consisting of oxalate of iron.
(Ox`a*lur*am"ide) n. [Oxaluric + amide.] (Chem.) Same as Oxalan.
(Ox`a*lur"ate) n. (Chem.) A salt of oxaluric acid.
(Ox`a*lur"ic) a. [Oxalyl + urea.] (Chem.) Pertaining to, or designating, a complex nitrogenous
acid related to the ureids, and obtained from parabanic acid as a white silky crystalline substance.
(Ox"a*lyl) n. [Oxalic + - yl.] (Chem.) (a) A hydrocarbon radical (C2O2) regarded as a residue
of oxalic acid and occurring in derivatives of it. (b) An old name for carbonyl. (c) An old name for
(Ox*am"ate) n. (Chem.) A salt of oxamic acid.
(Ox`a*meth"ane) n. [Oxamic + ethyl.] (Chem.) Ethyl oxamate, obtained as a white scaly
(Ox`a*meth"yl*ane) n. [Oxamic + methyl.] (Chem.) Methyl oxamate, obtained as a
pearly white crystalline substance.
(Ox*am"ic) a. [Oxalic + amido] (Chem.) Pertaining to, or designating, an acid NH2.C2O2.HO
obtained as a fine crystalline powder, intermediate between oxalic acid and oxamide. Its ammonium salt
is obtained by boiling oxamide with ammonia.
