Ammonium chloride syrup

Charge one-half of item 12 in a suitable stainless steel mixing vessel, heat to 90° to 95°C, and add and mix item 11. Mix for 1 hour at 90° 

In separate vessels, charge 100 mL of item 12 in each and mix items 3, 4, or 10 separately. Then mix them all together and stir well.

The substance is best prepared by dissolving cobaltous carbonate in the smallest possible quantity of hydrochloric acid, treating the cold solution with a mixture of concentrated aqueous ammonia and ammonium carbonate, and oxidising by means of a stream of air drawn through the liquid. When oxidation is complete ammonium chloride is added and the whole evaporated to a syrup dilute hydrochloric acid is added to remove carbon dioxide, and the liquid is saturated with ammonia gas to decompose any tetrammino-salt formed. On the addition of concentrated hydrochloric acid the salt crystallises out on cooling.6...

Substituting cobalt chloride for the nitrate, proceed as in Exercise 68, following the directions until the oxidation is complete and a deep red solution is obtained. Add 5 g. of ammonium chloride and evaporate the solution to a syrup. Then add dilute hydrochloric acid to decompose all carbonate and saturate the solution with ammonia gas to decompose any tetrammine salt that may be present. Add an excess of concentrated hydro-... 

If the reaction, say, with cyanogen chloride, is carried out in ether solution, ammonium chloride precipitates and is filtered off, and the cyanamide is procured as a syrup by allowing the ether solution to evaporate spontaneously and later as crystals by allowing the syrup to stand over sulfuric acid in a desiccator. Cyanamide may also be prepared by removing the component atoms of hydrogen sulfide from thiourea by means of mercuric oxide. Thionyl chloride effects the corresponding removal of water from urea. 

Emetics, when administered in small doses, act as expectorants and are used in inflammatory conditions of the respiratory tract to increase the bronchial secretion and render it less tenacious. The most commonly used expectorants are ipecac, ammonium chloride, and apomorphine. The last named is administered in doses of 1 mg in the form of an elixir or syrup. Apomorphine injected in subemetic doses of 1 to 2 mg is also used as a sedative in the delirium following anesthesia, in acute alcoholic psychosis, and in patients manifesting severe agitation prior to anesthesia. 

Licorice extracts are used extensively as ingredients in cough drops and syrups, tonics, laxatives, antismoking lozenges (see lobelia), and other preparations. They are also used as flavoring agents to mask bitter, nauseous, or other undesirable tastes in certain medicines (e.g., cascara, ammonium chloride, and quinine preparations). 

Determination of Orthophosphates.—(1) With Silver Nitrate.— This depends upon the precipitation of silver orthophosphate in solutions of low and controlled acidity. In the assay of commercial 85 per cent, phosphoric acid of density 1-710 the syrup is diluted to a convenient volume and an aliquot part is taken which contains about 0-1 gram of H3P04. It is neutralised to phenolphthalein with approximately decinormal alkali (free from chloride). 50 c.c. of decinormal silver nitrate are then added while the solution is kept neutral to litmus by stirring in zinc oxide or a suspension of the hydroxide. The whole or a measured part of the filtered solution is acidified with nitric acid and, after the addition of ferric alum, the unused silver nitrate is titrated with standard decinormal ammonium thiocyanate in the usual manner. Alkali phosphates may also be determined in this way. 

This compound yields a syrup of mixed acetates, from which two chlorides majr be obtained. One of these forms small, hard, white prisms, M.pt. 112° to 113° C., soluble in alcohol but insoluble in water, whilst the second isomer is resinous. The crystalline variety is best obtained as follows Equimolecular quantities of the eugenol compound and mercuric acetate in seven times the bulk of water are heated for one hour on the water-bath, and after cooling poured into four times the volume of 3 per cent, sodium chloride solution. After standing for several days the product separates out, and on recrystallisation melts at 112 5° C. It is unchanged by ammonium sulphide or hydrate, hut decomposed by warm dilute hydrochloric acid. Its constitution is given as (OMe)2GeH3-CH2 CH=CH3.Hg(OH)Cl. 

The filtrate is evaporated to a sjmip and to the syrup are added about 200 mL. of saturated aqueous sodium chloride solution. Sufficient aqueous ammonium hydroxide is added to make the solution slightly basic and the basic solution is extracted several times with 100 mL. portions of ethylene dichloride. The ethylene dichloride extracts are combined and evaporated in vacuo yielding a residue comprising ergonovinine. 

The free alkaloid occurs in very deliquescent, irregular crystals, or, if not perfectly dry, a colorless, odorless, and tasteless, but strongly alkaline syrup readily soluble in all proportions in water and in alcohol very sparingly soluble in chloroform insoluble in ether. It is a more powerful base than ammonium hydroxid, forming an alkaline carbonate and neutral salts with other acids. "When decomposed it yields trimethylamin. Its chloroplatinate crystallizes in octahedra. Its chlorid forms colorless, brilliant, deliquescent needles.
