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.
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.
The analysis reagent is a masking agent for detecting lead, nickel, phosphorus, metals and the like.
Contact can irritate the eyes and skin; High concentration exposure can irritate the nose, throat and lungs. Stored in a closed container, placed in a cool and ventilated place.
