(1) QUININE A., C.:nH„4N202+l or 3H20 ; usually amorphous, but crys- talline needles, containing 3H20, are gradually formed from the precipi- tate by ammonia, and crystals are also obtainable from solutions in petroleum ether and benzene, but not from ether. M.P. 171°-172° when anhydrous, 120° hydrate, or 57° the trihydrate (O. Hesse) ; laevo-rotatory, [a]R= -141'3 in alcohol (De Vrij) ; very bitter ; fluorescent in acid solu- tion ; alkaline reaction. Solubility : 1 in 1,667 cold water and 1 in 902 boiling (Sestini), or 1 in 364 cold and 1 in 267 boiling (Duplos) ; 1 in 2 alcohol of sp. gr. 082, and even easier soluble at boiling heat; 1 in 23 cold ether (Vandenburg), or 1 in 60 (Merck), but much more readily when freshly precipitated ; very soluble in chloroform, about 1 in T8 (Pettenkofer) ; also dissolved by benzene, amyl alcohol, petroleum ether, carbon bisulphide, and oils. It is removed from alkaline solutions by petroleum ether, benzene, ether, chloroform, and amyl alcohol. The salts are generally less soluble than those of Cinchonine.](https://iiif.wellcomecollection.org/image/b21503023_0042.jp2/full/800%2C/0/default.jpg)
