Propyl methacrylate nitrile (Methacrylonitrile, referred to as MAN) is an important organic chemical raw material, which is widely used in polymer synthesis, medicine, pesticide, fiber and other fields. This article will detail the properties and uses of propyl methacrylate nitrile.

1. Propyl Methacrylate Nitrile Properties

Propyl Methacrylate Nitrile is a colorless transparent liquid with a strong pungent odor. It has good chemical stability and can remain stable in acidic and alkaline environments, but it will decompose under the action of strong oxidants. Propyl methacrylate nitrile has a high boiling point of 97~98 ℃, a density of 0.94g/cm³, a refractive index of 1.4047, and can be miscible with water, alcohol, ether and other solvents.

methyl methacrylate nitrile molecules contain carbon-carbon double bonds and cyano groups, making it highly reactive, prone to polymerization, addition, substitution and other reactions. At the same time, propyl methacrylate nitrile also has high toxicity, and it is necessary to pay attention to safety during use.

2. of Propyl Methacrylate Nitrile Use

1. Polymer Synthesis

Propyl Methacrylate Nitrile can be used as a monomer to generate a polymer through polymerization. It can be copolymerized with other monomers to obtain different properties of polymer materials, such as propylene methacrylate-styrene copolymer (MAS), with excellent oil resistance, heat resistance and oxidation resistance, widely used in the manufacture of high temperature, oil-resistant products, such as automotive parts, electrical insulation materials.

2. pharmaceutical intermediates

of propyl methacrylate nitrile can be used as pharmaceutical intermediates for the synthesis of some drugs. For example, it can be reacted with hydroxylamine to produce propyl methacrylate nitrile-hydroxylamine, which is further reacted to produce the anticancer drug cyclophosphamide.

3. pesticide manufacturing

of propyl methacrylate nitrile can be used to manufacture some pesticides, such as reaction with aldehyde compounds to obtain propyl methacrylate nitrile-aldehyde compounds, with good insecticidal and bactericidal effects.

4. Fiber Material

Propyl methacrylate nitrile can be used as a fiber material, and fibers can be made by a spinning process. The copolymer fiber obtained by copolymerization with other monomers has excellent properties, such as heat resistance, chemical resistance, UV resistance, etc., and is widely used in the manufacture of textiles, industrial fabrics and other fields.

In conclusion, as an important organic chemical raw material, propyl methacrylate nitrile is widely used in polymer synthesis, medicine, pesticide, fiber and other fields. Pay attention to safety during use and avoid contact with sensitive parts such as skin and eyes.
