Methyl acrylate nitrile (Acrylonitrile, referred to as MAN) is an important organic chemical raw materials, in the field of chemical production has a wide range of applications. This article will detail the properties and uses of acrylic acid methyl ester nitrile.

1. the nature of methyl acrylate nitrile

methyl acrylate nitrile is a colorless transparent liquid with a pungent odor. Its molecular formula is C4H5NO and its molecular weight is 83.09. Methyl acrylate nitrile has a boiling point of 101.2°C, a melting point of -76.5°C and a density of 0.94g/cm3. It is insoluble in water, but soluble in organic solvents, such as ethanol, ether and so on.

acrylic acid methyl ester nitrile chemical properties of active, prone to polymerization, addition, hydrolysis and other reactions. It is prone to hydrolysis under acidic or alkaline conditions to produce acrylic acid and methanol. In addition, methyl acrylate nitrile can also react with aldehydes, ketones and other compounds to generate corresponding alcohols.

2. the use of acrylic acid methyl ester nitrile

1. production of polymer materials

acrylic acid methyl ester nitrile can be used as a monomer, through polymerization reaction to generate polymers, such as polyacrylic acid methyl ester, polyacrylonitrile and so on. These polymers have good mechanical properties, chemical corrosion resistance, heat resistance, etc., and are widely used in plastics, rubber, fibers and other fields.

2. the production of synthetic fiber

acrylic acid methyl ester nitrile can be used as a raw material for synthetic fiber, through the polymerization reaction to generate polyacrylonitrile fiber (acrylic). Acrylic has good warmth, elasticity and abrasion resistance, and is widely used in textile and clothing manufacturing.

3. production of surfactant

acrylic acid methyl ester nitrile can be used as a surfactant raw material, through the hydrolysis reaction to produce acrylic acid and methanol. Acrylic acid can be further processed into acrylate surfactants, which are widely used in washing, emulsification, dispersion and other fields.

4. Production of pharmaceutical intermediates

acrylic acid methyl ester nitrile can be used as raw materials for pharmaceutical intermediates, used to produce some drugs and pharmaceutical intermediates, such as vitamin B3.

In conclusion, methyl acrylate nitrile is an important organic chemical raw material and has a wide range of applications in the field of chemical production.
