1,3-Dichloro-5,5-dimethylhydantoin Chemical Properties,Uses,Production

Chemical Properties

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

Uses

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

Uses

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

Definition

Methionine hydroxy analog c. 90%.

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.

Safety Profile

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.

Potential Exposure

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.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

Shipping

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

Purification Methods

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.]

Incompatibilities

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)

Waste Disposal

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
