What is 3-Aminophenol?
m-Aminophnol (MAP) is a widely used fine chemical raw material. With the development of facsimile technology and agricultural technology, the demand for m-aminophenol is increasing year by year as a colorless pressure/heat-sensitive material, pesticide intermediate, and API. In 2012, China’s MAP consumption was as high as 4000t; the country with the largest consumption of m-aminophenol abroad was Japan, whose consumption in 2013 was close to 2500t. In recent years, due to the control of environmental pollution and water and soil pollution, various environmental protection policies have been introduced one after another, and many domestic MAP production plants have withdrawn the project. Therefore, it is urgent to find out the MAP green production route. In medicine, it can be used to make p-aminosalicylic acid, a good medicine for treating tuberculosis. In the dye industry, m-aminophenol can be used to make N, N-trimethyl-3-aminophenol, which is used as a mordant and basic dye intermediate; Nitrogen dye intermediates, used to make N, N-diethyl-3-aminophenol, used as various dye intermediates and anti-corrosion agents for jet fuel; used to make fur dyes such as fur brown, fur yellow, etc. In addition, m-aminophenol can also be used as a catalyst for organic chemical reactions, such as the polymerization of propylene oxide and the dimerization of acrylonitrile, etc., as a metal anti-corrosion agent and alloy herbicide, insecticide in alkaline medium, for the production of anti-corrosion Oxygen, stabilizer, developer, etc.
In foreign countries, m-aminophenol is mainly used in the production of dyes and pesticides. For example, in Japan, 78% of its domestic consumption is used for dyes, and 70% of dye consumption is used for the production of functional leuco dyes. The consumption of traditional dyes is only 30%. In particular, the production of colorless pressure/thermosensitive dyes occupies an absolute dominant position. With the development and popularization of facsimile technology, the market demand for colorless pressure/thermosensitive dyes develops rapidly. From the mid-1980s to the early 1990s, the average annual growth rate of this type of dye in Japan was as high as 26.6%. In recent years, the growth rate has slowed down, but it is still a major field of growth in the world’s demand for m-aminophenol. In addition, the market demand for traditional dyes produced from m-aminophenol remained basically stable.
3-Aminophenol Uses
The main use of m-aminophenol is as a dye intermediate and photographic developer. Acid dyes, direct dyes, sulfur dyes, azo dyes, mordant dyes and fur dyes can be manufactured. m-aminophenol and p-aminophenol are pharmaceutical raw materials, raw materials for herbicides, fungicides and insecticides, and thermosensitive pigments. Ortho-aminophenol is also used as an inhibitor of metal alkaline corrosion, hair dye, rubber anti-aging agent, antioxidant, stabilizer, petroleum additive, catalyst for organic reactions, chemical reagent (m-aminophenol is a gold and silver assay reagent), Intermediates of organic synthesis, etc.
Another important use of m-aminophenol is to synthesize anti-tuberculosis drugs. In 2004, the demand for m-aminophenol for anti-tuberculosis drugs in my country was about 200 tons. The average annual growth rate of demand for m-aminophenol is expected to be 5% in the next few years.
The pesticide industry is also an important consumption field of m-aminophenol. Some fluorine-containing insecticides and fungicides use m-aminophenol as raw material, but due to the small number of varieties, the output is relatively small.

It is mainly used in the production of anti-tuberculosis drug sodium p-aminosalicylate. Since 1993, the production capacity of sodium aminosalicylate in my country has basically remained at 500-600 tons, but the output is only about 100 tons, and the consumption of m-aminophenol is more than 70 tons. Because tuberculosis is easy to produce bacterial resistance when sodium aminosalicylate is applied, and the domestic tuberculosis is decreasing day by day, it is expected that the output will not increase much in the next few years.
Dyes
It is mainly used in the production of dye intermediate N,N-diethylaniline in China, and then to synthesize various dyes and coumarin fluorescent whitening agents. At present, the output of m-hydroxy N,N-diethylaniline in my country is about 2000 tons/ However, some domestic enterprises still use sodium m-nitrobenzene sulfonate as raw material to produce m-hydroxyl N, N-diethylaniline due to the high price of m-aminophenol and high production cost, which limits m-aminophenol to a certain extent Application development of aminophenol. If the domestic m-aminophenol can reduce the cost, and the price is lowered a little, then the consumption market of m-aminophenol in the dyestuff aspect can be effectively developed. Only m-hydroxy N, N-diethylaniline consumes about 1400 m-aminophenol per year. Ton. With the eastward movement of the production and trade center of the world’s dyestuff industry, another major consumption route of China’s m-aminophenol is export. At present, more than 60% of my country’s total output of m-aminophenol is for export.
As an important organic intermediate, especially as an important functional dye intermediate, m-aminophenol has good development potential and market prospects. However, the current technology used to produce m-aminophenol in my country is backward, resulting in a large amount of The three wastes pollute the environment. Today, with increasingly stringent environmental protection requirements, the production of aminophenol by the nitrobenzene sulfonation alkali solution has no great development prospects. Therefore, the pace of technological transformation should be accelerated, so that the new process of synthesizing m-aminophenol by resorcinol ammonolysis can be industrialized in my country as soon as possible.
Pesticide industry
It is mainly used in the production of m-hydroxyphenyl ethyl carbamate, which is the raw material for the production of beetin and beetan. Other aspects are less used, such as six steps of acylation, rearrangement, benzylation, reductive hydrolysis, condensation, and cyclization to synthesize naphthoquinate, a quinoline anticoccidial drug; Friedlander reaction through the intermediate N-acetyl Synthetic fungicides based on m-aminophenol, chlorhydramine and flurustamine.

In recent years, with the application of composite materials and polymer resins more and more widely, MAP is used as a monomer for condensation reaction to prepare graphene/nickel oxide-poly(aniline-m-aminophenol) composite materials for supercapacitors and biosensors. Triglycidyl-m-aminophenol epoxy resin. The synthesized composite material has stronger conductivity, smaller electrode electrode, better capacitive performance, and better cycle stability; in addition, MAP has dual properties of nitrogen and amine, and has strong carcinogenicity After entering the drinking water, it will pose a serious threat to human life and health. The MAP in the water body is removed by chlorination and oxidation.
Preparation of 3-Aminophenol
Using m-aminobenzenesulfonic acid as raw material, it can be obtained by alkali fusion and acidification. Stir m-aminobenzenesulfonic acid with water to form a slurry, heat to 60°C, add caustic soda solution dropwise to make the pH 7-8, and filter to obtain m-aminobenzenesulfonic acid sodium salt solution. Put solid caustic soda or liquid caustic soda into the alkali melting pot, heat to melt or evaporate to concentrate, and gradually add m-aminobenzenesulfonic acid sodium salt solution at 275°C. After the addition was completed, the reaction was continued at 275°C for 75 minutes. Dilute the material in sodium sulfite washing solution, filter and separate sodium sulfite. Add 31% hydrochloric acid to the sodium m-aminophenolate solution after separation of sodium sulfite at a temperature below 50°C until it becomes neutral. Cool down to 35°C, precipitate crude m-aminophenol, filter, put the filter cake into the distillation pot, vacuum distillation, and distill the refined m-aminophenol through a tablet machine to obtain a flake product. The yield is 60%. Industrial product m-aminophenol is white crystal, melting point 119-123℃, content ≥98%.
