1 3-Dichloro-5 5-dimethylhydantoin (DCDMH)
Properties:
1,3-Dichloro-5,5-dimethyl hydantoin (DCDMH) is also known as dichloro-dimethyl hydantoin. It is a white tetrahedral prism crystal powder (industrial products have various specifications such as granular and flake). It has a slightly irritating smell of chlorine, which is easy to absorb moisture and is partially hydrolyzed after moisture absorption.
1,3-Dichloro-5,5-dimethyl hydantoin is easily soluble in organic solvents such as chloroform, dichloromethane, carbon tetrachloride, ethylene dichloride, symmetric tetrachloroethane, benzene, and concentrated sulfuric acid. The DCDMH turns brown when heated to the boiling point and burns quickly.
