N,N Dimethyl aniline P touldine(CAS : 99-97-8)

a colorless or light yellow oily liquid with the smell of rotten eggs, melting point 130.31℃, boiling point 211.5-212.5℃, weight at room temperature 0.9287~0.9366g/mL, refractive index 1.5360~1.5470, insoluble in water, soluble in certain Organic solvent, decomposes when exposed to light.

Usage: As an effective photoinitiator for acrylonitrile (AN) polymerization, it is widely used in the production of rapid self-setting dental materials, molding materials and acrylic anaerobic adhesives. The polymerization speed is proportional to the 1.62 power of the AN concentration and the 0.62 power of the DMT concentration. This product is usually used as an accelerator. In addition, it can also be used as a curing accelerator for unsaturated polyester resin and used to improve the permeability of capsule shells. DMT is a polymerization accelerator, such as dental trays for dental implants. Its main component is methyl methacrylate, with peroxide as the initiator. The usual polymerization process is to solidify by heating in boiling water at 100°C for 40 minutes. . If 0.8% of tertiary amines are added, such as N,N-dimethyl-p-toluidine and N,N-diisopropanol-p-toluidine, the molding can be cured by itself within a few minutes at room temperature. This is due to the fact that tertiary amines Amine catalysis accelerates the decomposition of peroxide at room temperature, thereby accelerating the polymerization process of methyl methacrylate. In addition to dental materials, foreign plexiglass polymerization also uses a catalytic self-condensation process. Adding 0.8% DMT during polymerization promotes both polymerization and cross-linking. This saves labor and time, and can greatly improve the original quality. Equipment production capacity.
