iodocodeine

[Pref. iodo-, and English codeine (q. v.).] Ionian-school ruby color by transmitted light. Iodo-codeine is insoluble in water and ether, but di olves readily in alcohol, with a reddish-brown color. It gives off iodine when heated to 100°. i-od-o form, s . [Eng. iod(ine); o connect., and form ( yl ).] Chem.: CHI3. Obtained by heating iodine with alcohol mixed with sodium carbonate. Iodoform crystallizes in shining yellow six-sided hexagonal plates, which melt at 117. It smells like saffron. water, acidulated with sulphuric acid, in long silky needles, which melt at 196°. Di-iodosalicylic acid, C7H4I2O3, is a white amorphous ma , insoluble in water, but slightly soluble in alcohol and ether. It is soluble in water acidulated with sulphuric acid, from which it crystallizes in needle-shaped crystals. On being heated it does not melt, but at 214° is decomposed with separation of iodine. Tri-iodosalicylic acid, C7H31303. This acid is very unstable, decomposing during the proce of formation into carbonic anhydride and tri-iodophenol. i-ô-đồ-sul-phür'-ic, a. [Prefix iodo-, and Eng. sulphuric (q.v.).] Composed of iodine and sul i-o-do-me-cone, s. [Pref. iodo- , and Eng. me- con(in)e (q. v.).] Chem. CHO. C3H4103. A crystalline substance obpulphurica tained by treating pyro meconic acid with an exce of pro to chloride of iodine, and precipitating with potash. It is insoluble in water, but soluble in alcohol and ether, from which it crystallizes in yellow hexagonal plates having an odor of saffron. It has neither an acid nor an alkaline reaction, and sublimes at 90°. 1-o-do-me-thāne, s. [Pref. iodo- , and English methane (q. v.).] Chem.: CH3I. Methyl iodide. A colorle sweet smelling liquid, obtained by distilling 8 parts iodine, 15 parts wood-spirit, and 1 part phos phorus. It almost insoluble in water, has a specific gravity 2 199, and boils at 44°-45°. Its vapor density, referred to hydrogen as unity, is 71°.
