Methacrylonitrile

Methacrylonitrile is an organic compound with the formula CH₂=C(CH₃)CN. It is a colorless liquid, although commercial samples can be yellow due to impurities. In terms of its structure, the molecule features a nitrile and a vinyl group, the latter being characteristic of monomers for polymers.

Production

Methacrylonitrile is produced by the reaction of propionitrile with formaldehyde in the presence of a base, typically sodium hydroxide (NaOH). The reaction is a form of Aldol condensation.

Uses

Methacrylonitrile is primarily used as a monomer in the production of polymers and resins. It is also used in the production of coatings, adhesives, and sealants.

Safety

Methacrylonitrile is a highly flammable liquid and vapor. It can cause burns and eye damage, and may be harmful if inhaled. It is also suspected of causing genetic defects and may cause cancer.
