Caproic Ether

The caproate of ethyl, and must not be confounded with caproylic ether, which would be oxide of caproyl - a substance as yet unknown. It is prepared by distilling caproate of baryta, alcohol, and sulphuric acid together. It is a limpid, oily fluid, boiling at 324° Fahr., and po e ing an agreeable fruity odor, resembling that of pine-apple. Cap'romys, n. [ Gr.kapros , a boar, and mus , a mouse.] (Zool.) A genus of Rodent i a, of the Muridæ or Rat family. Ca'pron, in Illinois , a post-office of Boone co., 21 m. N.E. of Rock ford. Cap/royl, or Hex'yl, n. (Chem.) The radicle of caproic alcohol is termed hexyl, from being the sixth of the homologous radicles forming the alcoholic series. It is obtained by the electrolysis of enanthylate of potash as a fragrant oil, boiling at 397° Fahr. It is a permanent substance, and remains undecomposed when submitted to the action of sulphuric or moderately strong nitric acid; but by mixing the two it is changed into a fatty acid, supposed to be caproic acid. Cap'ryl, or Octyl, n. (Chem.) The eighth radicle of the homologous alcoholic series, obtained by treating the chloride of capryl with metallic sodium. Its properties have not yet been thoroughly investigated. Form . C16H17 Capryl'ic Acid, n. (Chem.) One of the volatile acids obtained by Chevreul during the saponification of butter. It is also obtained by the action of nitric or oleic acid. It is a colorle , oily liquid, insoluble in water, but soluble in alcohol and ether, with a disagreeable sudoriferous smell. It becomes solid at 50° Fahr., and boils at 457° Fahr. It is prepared by decomposing caprylate of baryta with sulphuric acid. It forms monobasic salts with the bases, which have not as yet been examined. Form . C16H1604
