PROPERTIES OF ETHYL METHACRYLATE NITRILE

Ethyl methacrylate nitrile (Acrylonitrile methyl acrylate, AMA), molecular formula C6H7NO2, is a compound containing a cyano group and a carboxylate group. Its molecular structure contains a vinyl group, so it can carry out radical polymerization reaction. It is usually a colorless to light yellow liquid with a certain pungent odor. Ethyl methacrylate nitrile has high reactivity and good solubility, and can be dissolved in a variety of organic solvents such as ethanol, ethyl acetate and so on.

physical and chemical properties

Ethyl methacrylate nitrile has a melting point of about -54°C, a boiling point of 176-177°C and a density of 1.02g/cm³. It has a high polarity and a high boiling point, making it a good solvent and intermediate in many applications. It has a refractive index of 1.420-1.422 and a flash point of 54°C (closed cup), showing a certain degree of flammability. Its chemical properties are active and can react with a variety of compounds, such as esterification, polymerization and so on.

Use

Ethyl methacrylate nitrile is widely used in chemical industry. It is an important monomer for the preparation of special polymer materials, especially in the preparation of acrylic copolymers, which can give polymers excellent heat resistance and mechanical properties. It is also used as an intermediate in organic synthesis, for the synthesis of various compounds, such as drugs, pesticides, dyes, etc. Ethyl methacrylate nitrile can also be used as a modifier for coatings and adhesives to improve product adhesion and durability.

Upstream raw materials

The production of ethyl methacrylate nitrile involves a variety of upstream feedstocks, including primarily acrylonitrile, methacrylic acid, and a catalyst. Acrylonitrile is the key raw material for the production of ethyl methacrylate nitrile, which is usually obtained by the oxidative dehydrogenation of propane. Methacrylic acid is produced by the hydrocyanation of propylene in the presence of a peroxide. In the synthesis process, a certain catalyst, such as a strong acid catalyst or a metal catalyst, is also needed to promote the reaction and improve the yield of the product.

Downstream Products

Ethyl methacrylate nitrile as an intermediate, can be derived from a variety of downstream products. For example, in synthetic resins, ethyl methacrylate nitrile can be used to produce special acrylic resins, which are widely used in coatings, adhesives, plastics and other fields. It can also be further processed into various functional monomers for the production of polymer materials with specific properties, such as high impact, heat or chemical resistance polymers.

storage method

Storage of ethyl methacrylate nitriles requires special attention to safety and stability. It should be stored in a cool, well-ventilated warehouse, avoid direct sunlight and high temperature environment to prevent thermal decomposition reaction. Storage containers shall be of corrosion resistant material such as glass or stainless steel and shall be kept sealed to prevent volatilization and oxidation. Appropriate fire fighting equipment, such as dry powder fire extinguishers or carbon dioxide fire extinguishers, should be provided in the storage area to deal with possible fire risks. Wear protective gloves and goggles during handling to avoid contact with skin and eyes.

Environment and safety

Due to the toxicity and irritation of ethyl methacrylate nitrile, its handling and use require strict compliance with safety regulations. The workplace should be equipped with good ventilation equipment, and operators should wear personal protective equipment, such as protective gloves, goggles and protective clothing, to prevent chemicals from contacting the skin and eyes. It is also necessary to pay attention to prevent leakage. If leakage occurs, personnel should be evacuated immediately and measures should be taken to deal with it, such as using adsorption materials to absorb the leaked liquid and properly dispose of it. Ethyl methacrylate nitrile waste should be disposed according to relevant regulations to avoid environmental pollution.
