| Physical and Chemical Properties | Bismuth subnitrate also known as bismuth oxynitrate, bismuth subnitrate. Formula 4 BiNO3(OH)2 · BiO(OH), molecular weight 1461.99. White crystalline powder or pearlescent scales. Odorless and tasteless. Relative density of 4.928, melting point of 250 deg C (decomposition),260 deg C to lose water. Slight deliquescence. See Light stability, such as mixed with silver, plus high temperature that yellowing and melting into oxides. Partial decomposition at 100 ° C, loss of water and nitric acid, insoluble in water and alcohol, soluble in hydrochloric acid, nitric acid and dilute sulfuric acid, water suspension was weakly acidic. Bismuth nitrate and water containing five molecules of crystal water were ground, ammonia was added, impurities were removed, and dried. Used as chromatographic analysis reagents, and used in the pharmaceutical industry, testing sugar and alkaloids, bismuth powder and antiseptic powder. |

| function and use | the pharmacological effect of bismuth nitrite is the same as that of bismuth subcarbonate, which has the function of protecting mucosa, converging, stopping diarrhea and weak sterilization. Clinical for Diarrhea, chronic gastroenteritis, peptic ulcer and other diseases. From bismuth nitrate and sodium nitrate at 30-35 deg C, pH is maintained between 1.7-2.0, obtained by hydrolysis reaction. [Function and use] after oral administration by the decomposition of intestinal bacteria to form nitrous acid, toxic to animals. In the inflammatory tissue surface can play a role of convergence and antibacterial and anti-inflammatory, for gastroenteritis and Diarrhea, can be prepared to scatter powder or 5%~ 10% ointment for external use. The Fistula was perfused with 25% bismuth nitrate paste. [Usage and dosage] Oral administration: a dose, pigs, sheep 2~6 grams, cattle, horses 10~30 grams, piglets 0.5~1 grams, dogs 0.3~1 grams, cat 0.15~0.3g, rabbit 0.4~0.8G, Mink 0.1~0.5G, dog dog 0.2~0.4g, poultry 0.1~0.3g. [Note and contraindications] a large number of long-term use, easy to nitrite poisoning. |
| production method | 1. 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 to obtain bismuth subnitrate. 2. The crystalline bismuth nitrate is made into a suspension solution, which is adjusted by adding refined sodium carbonate solution or ammonia water, and the reaction is continuously stirred, and the reaction product is filtered, washed and dried. 3. In the industry, a double decomposition method is adopted, and bismuth nitrate is added to water, and the double decomposition is carried out by adjusting pH = 1.7 to 1.9 with ammonia water or sodium carbonate. The reaction scheme is as follows. The process flow of the metathesis is as follows. Take crystalline bismuth nitrate [Bi(NO3)3 · 5H2O], add 1.5 times the amount of pure water to make a suspension, then quickly poured into 500L warm water (30~35 ℃), add refined sodium carbonate solution or ammonia water, adjust pH = 1.7~1.9, hydrolyze under constant stirring for 15min, and then discharge through high-frequency water changer or magnetic water changer, the reactant sodium bismuth powder is loose to generate microcrystals, and the clinical curative effect is improved. Since the present article is a basic salt of variable composition, its chemical composition varies depending on the metathesis conditions in the manufacturing process. For example, the chemical composition is similar to that of Bi2O3 · N2O5 · 2H2O at low temperature, and the chemical composition is similar to that of 2 Bi2O3 · N2O5 · H2O at high temperature. The double decomposition product is filtered off the mother liquor, and washed with warm pure water for 4 times until the pH value is about 4. This product should not be washed more, otherwise, wash more acid, abnormal phenomenon. The mechanism is: Further hydrolysis, free nitric acid. |
