Ammonium tartrate - Nature
Open Data Verified Data
colorless crystals. dl. 061. Soluble in water, the solution is acidic, in 20 ° C water solubility of 38. 65%, in 60 ° C water for 46. 52%; Very slightly soluble in alcohol. Thermal decomposition. Open air will gradually evolve ammonia and acidic reaction. Flammable, but not easy to ignite, fire can produce toxic gases.

Ammonium tartrate - Preparation Method
Open Data Verified Data
tartaric acid was dissolved in water and ammonium carbonate was added slowly until the solution was slightly alkaline to phenolphthalein. After boiling, it is evaporated on a water bath, and when a crystalline film appears, it is rapidly filtered, and the filtrate is cooled, filtered and dried to obtain a finished product. Alternatively, tartaric acid and ammonia are reacted in ethanol to form an amorphous powdery precipitate. The product was obtained by filtration, washing with ethanol and ether, and drying.

| use | used in pharmaceutical industry, etc. masking agent for determination of lead, nickel, phosphorus, niobium, etc. Used as analytical reagents and organic synthesis intermediates. |
| production method | (1) tartaric acid is dissolved in water by the action of tartaric acid and ammonium carbonate, and ammonium carbonate is slowly added until the solution is weakly alkaline to phenolphthalein. Boil for 20-30min. Evaporate in a water bath, filter quickly when a crystalline film appears, cool the filtrate, filter, and dry the crystals at 40°C to obtain the finished product. The yield is 80%. (2) The reaction of tartaric acid and ammonia in ethanol will pass ammonia into the ethanol solution of tartaric acid to generate amorphous powder precipitate. Filter, wash with ethanol and ether, and dry to obtain the finished product. |
