Methacrylamide Usage And Synthesis
Chemical Properties white to very slightly yellow crystals
Uses A monomer for acrylic resins.
Safety Profile Poison by intraperitoneal route. Moderately toxic by ingestion. Human systemic effects by inhalation: degenerative brain changes and liver and hdney changes. When heated to decomposition it emits toxic fumes of NOx.
Purification Methods Crystallise the amide from *benzene or ethyl acetate and dry it under vacuum at room temperature. [Beilstein 2 IV 1538.]
