Page 903 - Next add 50 cc of the soda solution, or sufficient to make the reaction strongly alkaline, pouring it down the side of the flask so that it does not mix at once with the acid solution. Connect the flask with the condenser, mix the contents by shaking, and distil until all ammonia has passed over into the standard acid. The first 150 cc of the distillate will generally contain all the ammonia. This operation usually requires from forty minutes to one hour and a half.
Page 896 - To the filtered liquid (representing 5 grammes of opium) add 5 cc of alcohol and 25 cc of stronger ether, and shake the mixture ; then add the chloride of ammonium, shake well and frequently during half an hour, and set it aside for twelve hours.
Page 775 - Chinese oil of peppermint; colorless, acicular, or prismatic crystals, having a strong and pure odor of peppermint, and a warm, aromatic taste, followed by a sensation of cold when air is drawn into the mouth.
Page 553 - A mixture of hydrocarbons, chiefly of the methane series, obtained by distilling off the lighter and more volatile portions from petroleum, and purifying the residue.
Page 895 - ... minutes, and return the whole to the filter. When the liquid has drained off, wash the residue, as before, until the second filtrate measures 150 cc, and finally collect about 20 cc more of a third filtrate. Evaporate...
Page 474 - Antimony trioxide so prepared is "a heavy, grayish-white powder without odor or taste, and permanent in the air. "Almost insoluble in water, and insoluble in alcohol. Nitric acid fails to dissolve it, but it is readily soluble in hydrochloric acid without effervescence, and also in a warm solution of tartaric acid, or in a boiling solution of potassium bitartrate. When heated the oxide turns yellow, becoming white again on cooling...
Page 903 - The flask is then removed from the flame, held upright, and, while still hot, potassium permanganate dropped in carefully and in small quantities at a time, until, after shaking, the liquid remains of a green or purple color. After cooling, the contents of the flask are transferred to the distilling flask with...
Page 897 - Cc of water, filter the solution through a small filter, and wash the filter and residue with water, until all soluble matters are extracted, collecting the washings separately. Evaporate, in a tared capsule, first, the washings to a small volume, then add the first filtrate, and evaporate the whole to a weight of 10 Gm.
Page 896 - Now let the filter dry in the air, and pour upon it the liquid in the bottle, in portions, in such a way as to transfer the greater portion of the crystals to the filter. Wash the bottle, and transfer the remaining crystals to the filter, with several small portions of distilled water, using not much more than 10 cc in all, and distributing the portions evenly upon the filter. Allow the filter to drain, and dry it, first by pressing it between sheets of bibulous paper, and afterward at a temperature...
