Application of Methylene Blue Trihydrate

Methylene Blue Trihydrate is widely used in chemical indicators, dyes, biological stains and drugs. Especially in the dyeing industry, it is used in the manufacture of ink, etc., and the amount is relatively large. In the following fields, methylene blue is also widely used.
1.Industrial field
Methylene Blue Trihydrate is a dye compound. Industrial-grade methylene blue is often used for dyeing cotton, silk, paper, etc., and can also be used for coloring bamboo and wood and making inks, lakes, etc. In addition, it is also often used as a bacterial stain, indicator, etc.
2.Pharmaceutical field
Methylene Blue Trihydrate has been used in the medical field for a long time. Due to the redox properties of methylene blue, it can be used to relieve cyanide, nitrite, aniline, acetanilide poisoning, or methemoglobinemia caused by drugs such as sulfonamides. In recent years, scholars have also conducted research on the application of methylene blue and its metabolites in various bacterial and viral infections, cancer and central nervous system diseases such as depression, schizophrenia, Alzheimer’s disease and other diseases.
3. Aquaculture field
Methylene Blue Trihydrate can be used as a disinfectant in aquatic product farming. The principle is that the ionic compound formed by Methylene Blue Trihydrate in aqueous solution can compete with the microbial enzyme system for hydrogen ions, inactivate the enzyme, and cause the microorganism to lose its viability; It also has a certain curative effect in the treatment of fish diseases such as small melon worm disease, oblique tube worm disease, red mouth disease, saprolegniasis and Litopenaeus vannamei larval viscera, and can also be used as an antifungal drug to reduce the risk of fish transportation. death rate.
4. areas of skin care
Studies have shown that Methylene Blue Trihydrate also has some potential in skin care. Methylene Blue Trihydrate can scavenge free radicals, stimulate cell proliferation in young and old dermal fibroblasts, and thus have certain effects on improving skin vitality, promoting skin elasticity and collagen synthesis, and protecting the skin matrix through the degradation of matrix metalloproteinases. effect. Therefore, methylene blue can be a promising agent in anti-aging cosmetics.

Preparation of Methylene Blue Trihydrate

Consider 2mol (418g) of p-aminodimethylaniline hydrochloride, placed it right into a reaction kettle with a thermometer, add 6L of water to liquify, include 0.41 mol (40g) of focused sulfuric acid dropwise under mixing to make the service acidic, and also add Zinc chloride option, aluminum sulfate remedy, salt thiosulfate remedy, and also 300mL sodium dichromate service were included, and also the reaction service was heated up to 40 ° C within 10 minutes under stirring, and also the hydrochloric acid solution of N,N-dimethylaniline Put it into the reactor, then instantly add the remaining 600mL salt dichromate option, as well as heat it to 70 ° C within 10 minutes; when the temperature level reaches 70 ° C, placed 2.87 mol (250g) of manganese dioxide right into the reactor, warmth it to 85 ° C, as well as maintain The temperature was reacted for 30 minutes, the temperature was naturally reduced to 50 ° C, as well as 7.14 mol (700g) of focused sulfuric acid was gradually included under stirring; Wash with 600mL liquid sodium chloride solution; move the filter cake to a 20L beaker, add 10L water, stir as well as warm to boiling on the electrical heating mantle, suction filter while it is hot, add 1.84 mol (250g) zinc chloride and also 25.64 mol (1500g) Sodium chloride, stir to dissolve, after that place the remedy at 4 ° C for 24h, suction filter, as well as completely dry at 50 ° C to get 460g of Methylene Blue Trihydrate zinc chloride salt; liquify the obtained zinc chloride salt in 10L of water, add sodium carbonate 0.52 mol (55.2 g), cool to space temperature, filter with suction, clean the filter cake with a small amount of water, include 17.09 mol (1000g) of sodium chloride, stir and liquify, place it at 4 ° C for 12 hrs, filter with suction, and filter the cake at 40-45 After drying out at ℃ for 12 hrs, 320 g of the unrefined product of Methylene Blue Trihydrate was acquired (loss on drying out was about 15%, and also the return was 42.5% based on anhydrous matter). Put the crude methylene blue into a conical flask, include 1280mL of 0.1 mol/L hydrochloric acid (1:4), heat as well as dissolve in a water bathroom at 60 ° C, location formation at space temperature, filter with suction, as well as recrystallize the filter cake when in hydrochloric acid of the same volume and concentration. The exact same quantity of water was recrystallized when, and the filter cake was dried at 40-45 ° C for 12 hrs to acquire 205g of Methylene Blue Trihydrate, with a loss on drying out of 14.6% and also a return of 64.3% based upon anhydrous matter. The complete yield is 27.4% based on the raw material p-aminodimethylaniline hydrochloride.

Main Uses of Methylene Blue Trihydrate

1. New fish quarantine
Methylene Blue Trihydrate can be used in new fish bags or in quarantine tanks for quarantine of new fish before entering the tank. Because of its mild medicinal properties, it is especially suitable for the quarantine of fry and small fish. In addition, it is also commonly used in the postpartum care of broodstock.

2. Control Saprolegnia
When used with salt, it can prevent saprolegniasis and the resulting rot.

3. Prevention and treatment of white spot disease and other external diseases
Spray the Methylene Blue Trihydrate solution in the whole tank, although the effect of the medicine is slow (it usually takes 7 days for a course of treatment, during which half of the water is changed and the medicine is added to maintain the concentration), but the damage to the fish is relatively small. (Recommended by Ito Fish Farm, Japanese players use this method more.)

4. Detoxify nitrite
Because the filter system of the fish tank is too weak or the nitrification system collapses due to other reasons, the nitrite content in the fish tank exceeds the standard and causes fish poisoning. You can use methylene blue medicine bath to treat methaemoglobinemia and rescue sub- Nitrate poisoning phenomenon.

Methylene Blue Trihydrate has a staining effect, the water in the fish tank will turn blue, and it will last for a long time, and it is easy to combine with the filter material, so it is best not to use this medicine in the original tank.
