General Description

Methacryloyl isocyanate is a chemical compound with the molecular formula C6H7NO2. It is used in the production of polymers and resin materials, including acrylics, adhesives, and coatings. Methacryloyl isocyanate reacts readily with a variety of compounds, including alcohols, amines, and thiols, to form stable bonds, making it a valuable building block in the synthesis of various materials. Its reactivity and ability to undergo polymerization reactions also make it useful in the development of specialty coatings and adhesives with specific properties, such as high strength and chemical resistance. However, methacryloyl isocyanate is toxic and can cause irritation to the skin, eyes, and respiratory system, necessitating proper handling and safety precautions during its use.

Method of preparing acylisocyanates

The invention relates to a novel process for the preparation of acyl isocyanates which consists in reacting oxalyl chloride with an N-trialkylsilylcarboxamide or an N,N-bis(trialkylsilyl)carboxamide. The process makes it possible to obtain acyl isocyanates in good yield, in particular acyl isocyanates derived from aliphatic amides, and under simplified reaction conditions.
