| 1,3-Dichloro-5,5-dimethylhydantoin Usage And Synthesis |
| Chemical Properties | Powder |
| Usage | Dantoin(R) DCDMH is an industrial bleaching agent based on dimethyl hydantoin. This product finds application wherever solid bleach is desired. |
| Usage | Dantoin(R) DCDMH LD (low dust) is an industrial bleaching agent based on dimethyl hydantoin. This product finds application wherever solid bleach is desired. |
| General Description | White powder with a weak chlorine odor. Conflagrates at 414°F (turns brown). Chlorine gas evolves > 410°F. |
| Air & Water Reactions | Sensitive to exposure to light, air, and moisture. Reacts with water or steam to produce toxic and corrosive fumes. |
| Reactivity Profile | 1,3-Dichloro-5,5-dimethylhydantoin reacts violently with xylene. 1,3-Dichloro-5,5-dimethylhydantoin is incompatible with strong acids, easily oxidized materials, ammonia salts and sulfides. 1,3-Dichloro-5,5-dimethylhydantoin will react with water or steam to produce toxic and corrosive fumes. At a pH of 9, 1,3-Dichloro-5,5-dimethylhydantoin decomposes completely. |
| Fire Hazard | Flash point data for 1,3-Dichloro-5,5-dimethylhydantoin are not available. 1,3-Dichloro-5,5-dimethylhydantoin is probably combustible. |
