This product is a variety of blue food coloring, which is used as a colorant for food, medicine and cosmetics. It is suitable for coloring cakes, candy, cool drinks and bean paste. It can be used alone or with other pigments to form black, adzuki bean, chocolate and other applications. It can be used for calibration and standardization of synthetic pigment detection methods in food, and can also be used as a working standard for daily analysis and detection. |
| Production method | From benzaldehyde o-sulfonic acid and a-(N-ethylphenylamino) m-toluenesulfonic acid in acidic medium to synthesize leuco. It is then oxidized by sodium dichromate or lead dioxide to obtain the pigment, neutralized and salted out with sodium sulfate, and then refined. In production, the condensation reaction generally takes tens of hours. If sulfuric acid and urea are used as the condensing agent, the reaction time can be reduced by about 1/5 compared with only sulfuric acid as the condensate. The preparation of brilliant blue is condensed by o-sulfobenzaldehyde and N-ethyl-N-(3-sulfobenzyl)-aniline, and then oxidized by sodium dichromate or lead dioxide. After the reaction, it is alkalized with soda ash, and then salted out with sodium chloride to obtain crude products. Dissolve the crude product in water, and then salt out with sodium chloride to obtain the finished product. Preparation of bright blue aluminum lake Aluminum hydroxide is prepared from aluminum salt such as aluminum chloride, aluminum sulfate, etc. and alkali such as sodium carbonate, and then added to the bright blue aqueous solution to precipitate the product. (1) preparation of bright blue. It is condensed by o-sulfobenzaldehyde and N-ethyl-N-(3-sulfobenzyl)-aniline, and then oxidized by sodium dichromate or aluminum dioxide. After the reaction, it is alkalized with soda ash, and then salted out with sodium chloride to obtain crude products. Dissolve the crude product in water, and then salt out with sodium chloride to obtain the finished product. (2) Preparation of bright blue aluminum lake. Aluminum hydroxide is prepared from aluminum salts such as aluminum chloride, aluminum sulfate and alkali such as sodium carbonate, and then added to the brilliant blue aqueous solution to precipitate the product. The condensate of ortho-benzaldehyde sulfonic acid and α-N-ethylphenyl amino) m-toluenesulfonic acid is oxidized into pigment with sodium dichromate or lead dioxide, neutralized and salted out with sodium sulfate, and then refined. Can be converted into aluminum lake. |
