C.I. 42780 - Introduction
Introduction
Methyl blue itself is a compound, used as a biological stain, and is often used as a disinfectant in medicine. Its appearance is a shiny red-brown powder, which is easily soluble in water, resulting in a blue water body. Because of the mild properties of methyl blue, it can be used for long-term medicated baths.
Artificial dyes
namely aniline dyes or coal tar dyes, there are many types and extremely wide applications. Its disadvantage is that it is easy to fade after sunlight, and aniline blue, bright green, methyl green, etc. are more likely to fade. Pay attention to the pH in the production, and avoid direct sunlight, and it can not fade for several years.
Methyl blue (English Methyl blue) is a weakly acid dye, soluble in water and alcohol. Methyl blue is widely used in the production technology of animals and plants. When combined with eosin, it can dye nerve cells and is also an indispensable dye in bacterial production. Aqueous solution is a living stain for protozoa. Methyl blue is very easy to oxidize, so it cannot be stored for a long time after dyeing.
biological activity
Methyl blue is a triaminotriphenylmethane dye. Methyl blue is widely used as an antibacterial dye in polychromatic staining and is used in histological and microbiological staining solutions. Methyl blue has been used as a model to study the effects of various catalysts on the photodegradation of dyes.
chemical properties
glitter reddish brown powder. It is very soluble in cold water and hot water and is blue. Dissolved in alcohol is green and blue. When it comes to concentrated sulfuric acid, it is reddish brown, diluted and blue-purple.
Use
it is mainly used to make pure blue and blue and black inks, and can also be used to prepare lake for blue printing table ink. It can also be used for dyeing and biocoloring of silk, cotton and leather, and can also be used as an indicator.
Mainly used to make pure blue ink and blue and black ink, and can also make lake
Production method
Basic fuchsin and aniline are condensed and sulfonated with fuming sulfuric acid, neutralized with sodium carbonate, and then acidified with sulfuric acid. Fuchsin (100%)370 sulfuric acid 1512 aniline (99%) 460 fuming sulfuric acid (104.5%) 1016 benzoic acid 10 yuan sodium sulfate 7 sodium carbonate (98%) 255
