properties | Calcium bromate is a white crystalline powder. The relative density was 3.329. Water loss at 180 ℃. Very soluble in water. It was heated to 180 °c as an anhydrous salt. Content: 99.8-100.5. |
Use | Calcium bromate can be used as dough quality improver; Food additive; Wheat flour, starch improver. wheat flour treatment agent; Yeast nutrition. Used in baked goods. |
preparation | bromine was added to an aqueous calcium hydroxide solution, and the solution was concentrated by heating. |
solubility in water (g/100ml) | grams dissolved per 100ml of water: 230g/20 ℃ |
identification test | 5% of the sample solution in dilute hydrochloric acid solution (TS-117) will appear transient yellow-red. The addition of sulfurous acid Dropwise to 5% of the sample solution resulted in the formation of a yellow color; When the sulfurous acid added was excessive, the yellow color disappeared again. |
content analysis | accurately weigh about mg of sample and dissolve in 50ml of water, A 250ml Erlenmeyer flask was implanted. 3g of potassium iodide and 3ml of hydrochloric acid were added, mixed and allowed to stand for 5min. 0.5 of cold water and 0.1 of starch test solution (TS-235) were added, and the mixture was titrated with mol/L sodium thiosulfate. A blank test was also performed. 0.1mol/L sodium thiosulfate is equivalent to Calcium bromate [Ca(BrO3)2? H2O]26.16mg. |
production method | from bromine vapor calcium carbonate or calcium hydroxide solution, calcium bromide is removed by crystallization and concentrated. |
