| | N-Methylolacrylamide Usage And Synthesis |
| Chemical Properties | White solid | | Uses | N-(Hydroxymethyl)acrylamide can be used as: - A monomer in the development of polymer gel dosimeters specifically designed for radiation therapy applications. The incorporation of NHMA enhances the sensitivity of the dosimeter to radiation doses.
- A monomer in the development of thermo-responsive polymeric gates, which exhibits thermo-responsive behavior. The incorporation of NHMA enhances the overall properties of the polymer, allowing for better control over the release mechanisms in response to temperature changes.
- A key monomer in the synthesis of double-hydrophilic and amphiphilic block glycopolymers, contributing to their self-assembly properties, biocompatibility, and functionalization potential. These characteristics make NHMA-based glycopolymers valuable for various biomedical applications, including drug delivery systems, biosensors, and tissue engineering.
| | Definition | ChEBI: N-Methylolacrylamide is a secondary carboxamide. | | General Description | A colorless or yellow aqueous solution. | | Air & Water Reactions | Soluble in water. | | Reactivity Profile | N-Methylolacrylamide may be sensitive to prolonged exposure to light. Polymerization and generation of heat and flames may occur on exposure to to heat or contaminants. Incompatible with strong oxidizers. | | Fire Hazard | Literature sources indicate that N-Methylolacrylamide is nonflammable. | | Synthesis | (1), the acrylamide is added to the reaction kettle containing solvent acetone, the polymerization blocking agent is added, and the temperature is raised to 42??45??;
(2), adding catalyst sodium methanol, adjusting the pH value in the reaction solution to 8.88;
(3), adding formaldehyde, adjusting the pH of the reaction solution to 8.5, and reacting at constant temperature for 1 hour;
(4), add phthalic acid, adjust its reaction solution pH to 7.2;
(5), cooling, crystallization, filtration to get the finished product N-hydroxymethacrylamide.
