| Methacrylamide Usage And Synthesis |
| Chemical Properties | white to very slightly yellow crystals | | Uses | A monomer for acrylic resins. | | Uses | Methacrylamide is a reagent used in the production of polymers and copolymers. It is also used as a raw material in the production of chemicals for industrial and professional use such as textiles, leather, fur, bulk, large scale chemicals (including petroleum products), fine chemicals, formulation [mixing] of preparations and/or re-packaging (excluding alloys), building and construction work, electricity, steam, gas, water supply and sewage treatment. | | 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.] |
