combining form, before a vowel, of Gr. χρῡσ-ός gold; chiefly in chemical terms; properly denoting compounds of a golden-yellow color, as Chrysamide [see AMIDE], an amide (N . H2 . C7 H(NO2)3 O), formed by boiling chrysammic acid with aqueous ammonia (Watts). Chrysamidic acid, an acid (NH3 . C7 H2(NO2)2 O2) forming salts called Chrysamidates. Chrysammic, -amic acid, an acid (C7 H2 N2 O6) produced by the action of nitric acid upon aloes, forming salts called Chrysammates. Chrysaniline, a brilliant golden-yellow dye (C20 H17 N3), obtained as a secondary product in the manufacture of rosaniline; also called aniline yellow. Chrysanisic acid, an acid (C7 H5 N3 O7) obtained, by the action of nitric acid on anisic acid, in small golden-yellow rhombic tables, forming salts called Chrysanisates. Chrysarobin, the medullary matter of the stem and branches of Andira Araroba dried and powdered, Goa Powder. Chrysazin, one of the dioxy-anthraquinones of the second group, crystallizing in golden-yellow laminæ, or red-brown highly lustrous needles; it is the basis of chrysamide and chrysammic acid, which is tetra-nitro-chrysazin. Chrysean, a sulphur derivative of hydrocyanic acid, obtained in yellow flocks. Chryseone, an orange-colored insoluble substance obtained by digesting calcium silicide with strong hydrochloric acid. Chrysene, a crystalline hydrocarbon (C18 H12) of the Anthracene group, obtained in bright yellow glistening scales. Chrysin, a substance obtained, in bright yellow shining plates, from the buds of Populus nigra; called also Chrysinic acid; its salts are Chrysinates.
