Monohydrate taste properties

The properties of normal ammonium carbonate.—Monohydrated ammonium carbonate forms elongated plates or flattened prisms, which smell of ammonia, and is presumably a product of the decomposition of the normal carbonate the pungent taste also affects the tongue as a caustic. The crystals were analyzed by J. Dalton, who found the composition to be very nearly that required for (NH4)2C03.H20, the products of all the different methods of preparation indicated by E. Divers have the same composition. E. Divers found that when exposed to air, the crystals become moist and opaque, lose ammonia and water, and form ammonium hydrocarbonate (NH4)2C03.H20=NH4HC03-j-H20-j-NH3. The salt thus becomes... 

Properties The monohydrate crystallizes in plates from dilute acetic acid. Bitter taste with sweetish aftertaste. Anhydrous form. Mp 198C. Not precipitated by digitonin. Soluble in glacial acetic acid, acetone, and alcohol slightly soluble in chloroform practically insoluble in water and benzene. 

C7H8N4O2, Mr 180.17, thin, bitter-tasting platelets, mp. 270-274 °C (monohydrate), moderately soluble in water, very soluble in hot water, alkali hydroxides, ammonia, dilute acids. A purine alkaloid from the leaves of the tea plant, also contained in matd (Ilex paragua-riensis and Paullinia cupana). The methylxanthines T., caffein(e), and theobromine are among the oldest known stimulants and drugs. Their pharmacological properties are compared in the table. In high doses T. can cause epilepsy-like convulsions. T. also exhibits antiasthmatic activity. ...
