Molecular Formula | C60H27AlI12O15 |
Molar Mass | 2537.682558 |
Storage Condition | 2-8 ℃, dry |
Physical and Chemical Properties | Properties The red aluminum lake is a purple-red fine powder, odorless, insoluble in water and organic solvents. It has better light resistance and heat resistance than red bright red, and is almost insoluble in water and organic solvents. It is easily soluble in salt liquid and dyed, and slowly soluble in aqueous solution containing acid and alkali. It has better light resistance and heat resistance than erythrosine. The dyeing power is related to fineness and dispersibility. |
Use | Uses can be used as food red pigment for powder food (such as cake powder, powder juice), fat products, cakes, such as sugar coating, coating, can also be used for food packaging materials printing, ink, dyeing of toys and tableware. |
Raw Materials | Fluorescein Sodium |
EPA chemical information | Spiro[isobenzofuran-1(3H),9'-[9H]xanthen]-3-one, 3',6'-dihydroxy-2',4',5',7'-tetraiodo-, aluminum salt (3:2) (12227-78-0) |

use
P> it can be used as food red pigment for powder food (such as cake prefabricated powder, powder juice), grease products, sugar coating, coating, etc., and can also be used for printing food packaging materials, printing ink, toys and tableware dyeing.identification method
(1)0.1g of this product is added with 5mL of steel hydroxide solution (110) and heated and dissolved in a water bath. Then add ammonium acetate solution (3 2000) to 100mL. If the solution is not clear, it can be centrifuged. Measure 0.5~5mL of clarification solution, and add ammonium acetate solution (3 200) to make 100mL in order to control the absorbance at 0.2~0.7. The maximum absorption wavelength of the solution should be 2nm 526.
(2) add 5mL sulfuric acid to 0.1g of this product, heat it on a water bath for about 5min, and shake it from time to time, and the color changes to light brown orange. Cooling, taking 2~3 drops of the upper clarification solution and adding 5mL of water to form orange-red precipitate.
(3)0.1g of this product is added with 10mL hydrochloric acid (13), heated to dissolve in a water bath, 0.5g of activated carbon is added, shaken and filtered, the filtrate is neutralized with sodium hydroxide solution (10), and then aluminum salt is measured.
