[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods, 2-ethylhexyl acrylate belongs to several categories of dangerous goods.

Properties of ethyl acrylate nitrile

Ethyl ethyl acrylate nitrile (Ethyl cyanoacrylate), chemical formula C6H7NO2, is a highly reactive organic compound. Its molecular structure includes a nitrile group (-CN) and an ester group (-COO-), which gives it unique chemical properties. The substance is colorless and transparent liquid at room temperature, with a certain degree of volatility and pungent odor. It has a density of about 1.1g/cm³, a boiling point of about 54-56°C, and a flash point of 85°C. Because its molecular structure contains polar cyano and ester groups, it has high adhesion and reactivity, and can quickly polymerize with a variety of substrates.

Ethyl ethyl acrylate nitrile use

Ethyl ethyl acrylate nitrile is mainly used as an adhesive, especially in super glue. Due to its fast curing characteristics, it is widely used in various industries and daily life, such as the assembly of electronic components, the bonding of auto parts, and the fixing of medical equipment. Ethyl ethyl acrylate nitrile also has important applications in the medical field, such as tissue adhesives in surgery, which can quickly close wounds and reduce the risk of infection. In addition, it is also used to manufacture high-performance coatings and sealants, and plays an irreplaceable role in these fields.

Upstream raw materials

The production of ethyl ethyl acrylate nitrile involves a variety of chemical feedstocks and intermediates. The main upstream feedstocks include acrylic acid, ethanol, and hydrogen cyanide (HCN). Acrylic acid is obtained by catalytic oxidation of propylene, while hydrogen cyanide is usually obtained by methanation or by-product recovery of acrylonitrile. In the production process, acrylic acid reacts with ethanol to form ethyl acrylate, and then reacts with hydrogen cyanide to form ethyl ethyl acrylate nitrile. This production process requires strict control of reaction conditions, such as temperature, pressure and catalyst selection, to ensure efficient and high purity product output.

Downstream Products and Applications

The downstream products of ethyl acrylate nitrile are mainly various types of adhesives and coatings. In the field of adhesives, its application is very wide, not only limited to traditional household and industrial uses, but also extended to high-tech fields, such as the packaging and assembly of electronic components. In terms of coatings, ethyl acrylate nitrile is used to prepare high-performance anti-corrosion coatings and special coatings due to its excellent adhesion and durability. With the development of technology, the application field of ethyl acrylate nitrile is still expanding, such as in 3D printing materials and new composite materials.

Production process

The production process of ethyl ethyl acrylate nitrile involves a multi-step chemical reaction, usually including an esterification reaction and a cyanation reaction. In the esterification reaction, acrylic acid and ethanol under the action of acidic catalyst to produce ethyl acrylate. Ethyl acrylate reacts with hydrogen cyanide in the presence of a basic catalyst to produce ethyl ethyl acrylate nitrile. The control of temperature and pressure throughout the reaction is critical to avoid side reactions and to ensure high selectivity of the reaction. The product after the reaction needs to remove impurities through distillation and purification processes to obtain high-purity ethyl acrylate nitrile.

storage method

Ethyl ethyl acrylate nitrile requires special care during storage because of its high reactivity and volatility. It should be stored in a cool, dry, well-ventilated place, avoid direct sunlight and high temperature environment to prevent product decomposition and performance degradation. Storage containers shall be made of corrosion-resistant materials and shall be well sealed to prevent leakage and moisture absorption. Due to its flammability, it should be kept away from fire and heat sources, and equipped with necessary fire fighting equipment. In order to prevent the polymerization reaction, an appropriate amount of a stabilizer, such as hydroquinone (hydroquinone), can be added during storage to inhibit the polymerization reaction.

Environmental and safety considerations

Ethyl ethyl acrylate nitrile is a chemically active substance, which requires attention to environmental and safety issues during use and handling. Because of its volatile and pungent odor, it should be used in a well-ventilated environment and wear appropriate personal protective equipment, such as gloves and protective glasses. The substance is irritating to the skin and mucous membranes, and should be rinsed with plenty of water immediately after contact. In the event of a leak, cover and soak up with an inert material such as sand, and dispose of the contaminant properly. Due to its flammability, dangerous goods management regulations should be strictly observed during transportation and storage to ensure safe operation.

Market Prospects

With the continuous progress of industry and technology, the market demand for ethyl acrylate nitrile continues to grow. In the electronics industry, automobile manufacturing, medical equipment and high-performance coatings and other fields, its application prospects are very broad. Especially in the field of high-end manufacturing and new materials, ethyl acrylate nitrile has broad market potential due to its excellent performance and versatility. In the future, with the increasingly stringent environmental protection regulations and the continuous advancement of technology, the application of green production technology and sustainable development will become an important direction for the development of the industry.

Conclusion

Ethyl acrylate nitrile as an important organic chemical raw materials, because of its unique chemical properties and a wide range of applications, has an important position in modern industry. From the selection of upstream raw materials to the control of the production process, from the safety of storage methods to environmental and safety considerations, every link is crucial. With the increasing market demand and the continuous progress of technology, ethyl acrylate nitrile will show its unique value and potential in more fields.
