white powder. Odorless and tasteless. d184. 930; Melting point 260 °c. Slight deliquescence. Soluble in dilute hydrochloric acid, nitric acid, dilute sulfuric acid, insoluble in water, ethanol and glycerol. Heat decomposition of bismuth oxide and cyanide.
bismuth nitrate pentahydrate is ground by adding water, then ammonia water is slowly added, free nitric acid is neutralized, the precipitate is washed by decantation, suction filtered, then washed with cold water and dried, bismuth nitrite can be prepared.
used in clinical tests to test sugars and alkaloids. Medicine for neutralizing gastric acid and astringent, for gastric and duodenal ulcer and Diarrhea. Also used in the manufacture of bismuth salt, ceramic glaze.
25kg plastic outer woven bag, or according to customer requirements. Contact with organic matter can burn and explosion. Risk code: GB 5.1 class 51524.
Use | stomach acid neutralizing and astringent, for the treatment of gastric and duodenal ulcer and Diarrhea, such as in clinical testing for testing sugar and alkaloids. Manufacturing bismuth salt, ceramic glaze. Medicine for neutralizing gastric acid and astringent, for gastric and duodenal ulcer and Diarrhea, etc. Used as chromatographic analysis reagent, clinical test for sugar and alkaloid, also used in the pharmaceutical industry |
production method | 1.20ml of a concentrated solution made of bismuth nitrate and 5% nitric acid were dropped into 500ml of boiling water with stirring. Cold, Suction filtration, washing. Dry at 30-40 °c. 2. Dissolve bismuth nitrate into saturated solution with distilled water, slowly add to a large amount of hot distilled water, stir hydrolysis: After the end of the reaction, add ammonia water with a density of 0.91 for neutralizing nitric acid, until the pH value of the solution is below 3, The Pb 2 Ag,? Cu2, Fe 3 and other impurity ions can be. The precipitation was completely allowed to stand. The supernatant was separated, and the precipitate was suction-filtered, then washed 5 to 6 times with cold water and dried in air. |
