Product Introduction:
M-Xylylenediamine, also known as meta-phenylenediamine, is an important organic chemical raw material. It is a colorless and transparent liquid at room temperature and pressure, with an almond-like smell. Its molecular formula is C8H12N2, molecular weight is 136.19, density is about 1.032g/mL, melting point is 14℃, boiling point is 274℃, refractive index is 1.57-1.572, and flash point is 113℃. It has good solubility and can be dissolved in water and a variety of organic solvents, such as alcohols, ketones, esters, etc., which makes it widely used in chemical production.
From the chemical structure point of view, M-Xylylenediamine belongs to aromatic polyamine compounds, and its molecule contains two amino functional groups, which are located on carbon atoms 1 and 3 of the benzene ring respectively. This special structure gives it unique chemical properties and reactivity. Due to the presence of amino groups, it can react chemically with a variety of compounds, such as reacting with acids to form salts, and reacting with epoxy resins to form cured products. In addition, its benzene ring structure also makes it stable to a certain extent, and it can maintain stable chemical properties in a wide range of temperature and pressure, which makes it possible to be used in different industrial environments.
In terms of physical properties, the viscosity of M-Xylylenediamine is similar to that of dibutyl phthalate, which makes it suitable for some applications that require specific fluidity. At the same time, it easily absorbs carbon dioxide in the air to form a white solid, which affects its storage and transportation conditions to a certain extent. It needs to be stored in a sealed and dry environment to avoid reaction with carbon dioxide in the air and deterioration.
The production process of M-Xylylenediamine is relatively mature. It mainly uses the meta-xylene ammoxidation method to prepare isophthalonitrile, and then catalytic hydrogenation to obtain M-Xylylenediamine. This synthetic route is mature in technology, mild in reaction conditions, easy to control, and can be mass-produced. In terms of storage, it needs to be packaged in plastic or iron barrels, 180 or 200 kg per barrel, fireproof, moisture-proof, and stored and transported in accordance with the regulations for flammable and toxic items. Store in a cool, dry warehouse at a temperature not lower than 15°C. Do not expose to air for a long time and avoid water.

M-Xylylenediamine has a wide range of applications in the chemical industry, one of the most important uses of which is as an epoxy resin curing agent. It can react chemically with the epoxy groups in epoxy resin to form a cured product with a three-dimensional network structure. This cured resin has excellent heat resistance, chemical corrosion resistance and mechanical properties, so it is widely used in electronic packaging materials, coatings, adhesives and other fields. Especially in some occasions that require high temperature resistance, water resistance and chemical corrosion resistance, such as insulation packaging of electronic equipment, composite materials in the aerospace field, etc., epoxy resins using M-Xylylenediamine curing agent can meet demanding performance requirements.
The polyurethane industry is another important application direction of M-Xylylenediamine. As a hard segment chain extender, it can adjust the microphase separation structure of polyurethane, giving the material higher tensile strength, wear resistance and high temperature resistance, and is widely used in high-performance elastomers, sole materials and industrial seals.In the rubber industry, M-Xylylenediamine, as a vulcanization accelerator and antioxidant, can effectively improve the heat-oxidative aging resistance of tires, conveyor belts and other products and extend their service life; in the field of pesticide synthesis, it participates in the construction of insecticide and fungicide molecular skeletons as an intermediate, which can not only enhance the efficacy but also reduce metabolic toxicity, which is in line with the trend of green pesticide development.
The demand for M-Xylylenediamine in the field of electronic chemicals and special fibers is growing rapidly. For example, in photoresist formulations, its derivatives can be used as photosensitive components to meet the needs of semiconductor precision processing by regulating the development rate and resolution; in aramid fiber production, its polycondensation reaction with acyl chloride monomers can prepare high-performance polyamide resins for bulletproof materials and high-strength ropes. It is worth noting that as emerging market countries take over the transfer of the global fine chemical industry, the technology research and development and production of M-Xylylenediamine are tilting towards China, India and other regions. This not only reduces the risk of cross-border supply chains, but also creates opportunities for local companies to participate in international competition.
The product advantage of M-Xylylenediamine is first reflected in its irreplaceable comprehensive performance. Compared with aliphatic amine curing agents (such as ethylenediamine), the aromatic structure of M-Xylylenediamine greatly increases the glass transition temperature of the cured product, allowing it to maintain dimensional stability under high temperature conditions; compared with similar aromatic amines (such as m-phenylenediamine), its low toxicity (LD50 is about 500 mg/kg) and liquid properties significantly improve operational safety and avoid the melting pretreatment process of solid raw materials. From the perspective of production technology, the maturity of fixed bed continuous technology has increased the primary amine selectivity of M-Xylylenediamine to more than 95%, and the amount of by-products (such as secondary amines and tertiary amines) has been reduced by 80%, which not only improves the utilization rate of raw materials, but also reduces the energy consumption of subsequent distillation. The annual production capacity of a single unit can reach 10,000 tons, and the scale effect is significant.
Environmental protection characteristics are one of the core competitive advantages of M-Xylylenediamine that distinguishes it from traditional chemical raw materials. Its synthesis process reduces the amount of ammonia inhibitors by optimizing the catalyst system and reaction conditions. The ammonia nitrogen content in the wastewater is reduced by more than 60% compared with the traditional process, which meets the increasingly stringent environmental protection regulations. On the user side, the low volatility and high reactivity of M-Xylylenediamine reduce the release of harmful gases during processing. With the development of waterborne epoxy systems, it can help downstream users achieve carbon emission targets. In addition, M-Xylylenediamine molecules do not contain restricted substances such as halogens and heavy metals, meet international chemical control standards such as REACH and RoHS, and clear barriers for its entry into the high-end markets in Europe and the United States.
From the perspective of market competition, M-Xylylenediamine has both the economy of bulk chemicals and the added value of specialty chemicals. Through catalyst improvement and process optimization, the purity of domestic products is stable at more than 99%, the price is 20%-30% lower than that of imported products, and the supply cycle is flexible, which can quickly respond to customer customization needs. In terms of technological innovation, domestic enterprises are committed to developing derivatives of M-Xylylenediamine, such as epoxy resin-acrylate hybrid monomers, hyperbranched polyamides, etc. These high value-added products will further increase the profit margins of the industrial chain. According to industry forecasts, with the explosive demand for high-performance materials in emerging fields such as new energy and 5G base stations, the global market size of M-Xylylenediamine is expected to exceed 500,000 tons in 2030, with a compound annual growth rate of 6%-8%.
