Translation of "Ammoniumhydrogencarbonat" in English

By introducing 125 g of solid ammonium bicarbonate in portions, the dyestuff is precipitated out.

Ammonium hydrogen carbonate decomposes with splitting off of ammonia in the pouring solution which is acid as the result of hydrolysis.

Those also suitable are alternatively ammonium hydrogencarbonate or ammonium formate.

Part of it may be replaced by ammonium hydrogen carbonate, or yeast may also be used.

The mixture was homogenized and the ammonium hydrogen carbonate was thus dissolved.

The carbonate is preferably ammonium hydrogencarbonate and/or ammonium carbonate.

Examples of substances which release ammonia include ammonium carbonate, ammonium hydrogen carbonate or urea.

The elution medium is preferably 50 mM ammonium hydrogencarbonate.

Here, for example, carbon dioxide is liberated more rapidly from ammonium carbonate or ammonium hydrogen carbonate than from ammonium carbamate.

The mixture was stirred and the ammonium hydrogen carbonate was thus dissolved.

With particular preference the carbonate is ammonium hydrogencarbonate (also called ammonium bicarbonate, ABC for short).

Basic ammonium salts such as ammonium carbonate, ammonium hydrogensulfate or ammonium hydrogencarbonate are particularly suitable as ammonia-releasing substances.

Preferred examples are ammonium carbonate, ammonium hydrogencarbonate, ammonium carbamate, and ammonium carboxylates such as ammonium formate and ammonium acetate.

Ammonium hydrogen carbonate can thus be dissolved in water, for example, whereby a draw solution is obtained.

The main types of nitrogen fertilizers are urea, ammonium sulfate, ammonium chloride, ammonium hydrogencarbonate and ammonium nitrate.

The destaining solution for CBB contains usually the buffer salt ammonium bicarbonate (NH4HCO3) and a fraction of 30%-50% organic solvent (mostly acetonitrile).

Ammonia caramel is prepared by the controlled heat treatment of carbohydrates (commercially available food grade nutritive sweeteners which are the monomers glucose and fructose and/or polymers thereof, e.g. glucose syrups, sucrose, and/or invert syrups, and dextrose) with or without acids or alkalis, in the presence of ammonium compounds (ammonium hydroxide, ammonium carbonate, ammonium hydrogen carbonate and ammonium phosphate); no sulphite compounds are used.

Sulphite ammonia caramel is prepared by the controlled heat treatment of carbohydrates (commercially available food grade nutritive sweeteners which are the monomers glucose and fructose and/or polymers thereof (e.g. glucose syrups, sucrose, and/or invert syrups, and dextrose) with or without acids or alkalis in the presence of both sulphite and ammonium compounds (sulphurous acid, potassium sulphite, potassium bisulphite, sodium sulphite, sodium bisulphite, ammonium hydroxide, ammonium carbonate, ammonium hydrogen carbonate, ammonium phosphate, ammonium sulphate, ammonium sulphite and ammonium hydrogen sulphite).

They are, in particular, of a pH value in the alkaline range of 7.5 to 11, adjustment being preferably made with ammonia, or ammonium hydrogen carbonate.

The precipitation of the dyestuff with ammonium bicarbonate can also be effected directly from the reaction solution which is obtained from the synthesis of the dyestuff.

Examples of compounds which accelerate the formation of iodide are, in addition to the acids mentioned, ammonium carbonate, ammonium bicarbonate, ammonium carbamate, urea, ammonium formate, formamide, ammonium oxalate, oxamic acid and oxamide.

A method as defined in claim 6 in which the preneutralization with ammonia is performed by first introducing ammonia gas during strong stirring of the solution and then ammonia is introduced by the decomposition of ammonium hydrogen carbonate added to the solution.

A method as defined in claim 10 in which ammonium carbonate is present in excess in the solution of uranyl carbonate at least prior to the introduction of ammonia gas, and is decomposed by maintaining the solution at a temperature between 15° and 40° C., and in which method the excess ammonium hydrogen carbonate is thereafter separated from the solution.

The compositions of the invention can additionally contain the usual cosmetic adjuvants, as for instance, alcohols, preferably ethanol, propanol and isopropanol, solvent facilitators, such as oxyethylated castor oil and 4-n-nonylphenoldecaglycol ether, as well as the conventional hair swelling promoters such as urea and alkalisulfites, further alkalinizing agents such as ammonia, monoethanolamine, ammonium hydrogen carbonate and ammonium carbonate, additional capillary active cation active compounds as for example, hexadecyltrimethylammoniumchloride, dyestuffs, perfume oils, glycerin, lanolin and other like hair treatment composition additives.

The invention provides therefore an improved process for the preparation of 1,2,4-triazole by cyclization of N,N'-diformylhydrazine in the presence of ammonia at elevated temperature, which comprises supplying the amount of ammonia required either (a) by forming it in situ from ammonium carbonate or ammonium hydrogen carbonate with heating to 150°-250° C., or (b) introducing gaseous ammonia into the N,N'-diformylhydrazine under the same conditions, while operating in both cases without pressure and in formamide as solvent, and constantly distilling off the water formed.

According to the operation mode of Example 1, 280 ml of formamide are heated to 170° C., and a mixture of 1.2 mols of N,N'-diformylhydrazine and 1.2 mols (94.8 g) of ammonium hydrogen carbonate is added. 16.9 g of water and formamide are distilled off.

The dyestuff is filtered off and washed with a solution of 25 g of ammonium bicarbonate in 200 ml of soft water.
