Methacrylamide (CAS 79-39-0) is a functional monomer with the molecular formula C₄H₇NO and a molecular weight of 85.10. Its structure features a reactive vinyl group alongside an amide group, making it a versatile intermediate in polymer chemistry and various industrial applications.
Mitsui methacrylamide is available in a high-purity grade, with product specifications of 99.5% purity and standard 25 kg/bag packaging. It typically appears as a white crystalline powder, exhibits solubility in water (202 g/L at 20°C), ethanol, and dichloromethane, and has a melting point of approximately 108°C and a boiling point of 215°C.
Key Applications
The unique reactivity of methacrylamide supports its use across multiple industrial sectors:
1. Polymer Synthesis: As a reactive monomer, it is used in the production of polymers and copolymers. It can be incorporated into acrylic resins to enhance properties such as heat resistance and crosslinking capability.
2. Textile Processing: It functions as a weight-improving agent for silk after degumming and finds application in the treatment of fibers and leather.
3. Coatings and Adhesives: The compound is used as a building block in self-crosslinking emulsions and heat-curing coatings, contributing to the performance of the final film.
4. Paper and Water Treatment: It serves as an intermediate for paper-making chemicals and is utilized in the formulation of industrial chemicals for water and sewage treatment.
5. Chemical Intermediate: It acts as a key precursor in the production of methyl methacrylate and other fine chemicals.
Storage and Handling
To maintain product quality and ensure safety, please observe the following guidelines:
Storage Conditions: Store in a sealed container in a cool, dry, and well-ventilated area. The storage temperature should be kept below 30°C to prevent degradation.
Incompatible Materials: Keep away from oxidizing agents, reducing agents, and acids to avoid hazardous reactions.
Moisture Sensitivity: The product is moisture-sensitive. Ensure the container is tightly closed after each use to prevent caking.
Safety Note: Methacrylamide is classified as a harmful substance. Avoid inhalation of dust and direct skin contact. Use appropriate personal protective equipment (e.g., gloves, safety goggles, dust mask) when handling the material.
