MSDS Information

• 1,3-Dichloro-5,5-dimethylhydantoin

1,3-ジクロロ-5,5-ジメチルヒダントイン 化学特性,用途語,生産方法

• 外観

  白色～微褐色、結晶性粉末～粉末

• 用途

  酸化剤。

• 用途

  ポリ塩化ビニルの安定剤、アミノ酸、医薬、農薬の中間体

• 化学的特性

  DCDMH is a combustible, white powder. Chlorine-like odor.

• 物理的性質

  White powder or four-sided crystals from chloroform with a chlorine-like odor. Aqueous solutions are acidic.

• 使用

  Dantoin(R) DCDMH is an industrial bleaching agent based on dimethyl hydantoin. This product finds application wherever solid bleach is desired.

• 定義

  Methionine hydroxy analog c. 90%.

• 一般的な説明

  White powder with a weak chlorine odor. Conflagrates at 414°F (turns brown). Chlorine gas evolves > 410°F.

• 空気と水の反応

  Sensitive to exposure to light, air, and moisture. Reacts with water or steam to produce toxic and corrosive fumes.

• 反応プロフィール

  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.

• 健康ハザード

  1,3-Dichloro-5,5-dimethylhydantoin powder in contact with water yields hypochlorous acid, which is an irritant of the eyes and mucous membranes.

• 火災危険

  Flash point data for 1,3-Dichloro-5,5-dimethylhydantoin are not available. 1,3-Dichloro-5,5-dimethylhydantoin is probably combustible.

• 安全性プロファイル

  Moderately toxic by ingestion. Mildly toxic by inhalation. A severe slun irritant. Mutation data reported. Avoid excessive contact because of effects of active chlorine on skin. Some of the hydantoins are central nervous system depressants. Mixtures with xylene may explode. Wdl react with water or steam to produce toxic and corrosive fumes. When heated to decomposition it emits toxic fumes of Cl and NOx. See also CHLORIDES.

• 職業ばく露

  It is used as a chlorinating agent, disinfectant, biocide, and laundry bleach. It is also used as a polymerization catalyst in making vinyl chloride; and in drug and pesticide synthesis.

• 環境運命予測

  Chemical/Physical. Reacts with water (pH 7.0) releasing hypochlorous acid. At pH 9, nitrogen chloride is formed (Windholz et al., 1983).

• 輸送方法

  UN1479 Oxidizing solid, n.o.s., Hazard Class: 5.1; Labels: 5.1-Oxidizer, Technical Name Required

• 純化方法

  Purify it by dissolving in conc H2SO4 and diluting with ice H2O, collect the solid, dry it in a vacuum and recrystallise it from CHCl3. It sublimes at 100o in a vacuum. It exhibits time-dependent hydrolysis at pH 9. [Petterson & Grzeskowiak J Org Chem 24 1414 1959, Beilstein 24 III/IV 1100.]

• 不和合性

  A strong oxidizer. Contact with water forms poisonous and corrosive gases. Mixtures with xylene may explode. Not compatible with moisture (especially hot water, steam), strong acids; easily oxidized materials (such as ammonia salts; sulfides, etc.); reducing agents; strong bases; ammonium salts; sulfides. Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur)

• 廃棄物の処理

  Incineration (815.5C/816C, 0.5 second for primary combustion; 104.4C/220F, 1.0 second for secondary combustion). The formation of elemental chlorine can be prevented by injection of steam or methane into the combustion process. Any nitrogen oxides may be abated by the use of thermal or catalytic devices
