Dichlorophenyl trichlorosilane is a strawcolored liquid.
(DICHLOROPHENYL)TRICHLOROSILANE is a straw colored liquid with a pungent odor. Material will burn though (DICHLOROPHENYL)TRICHLOROSILANE may require some effort to ignite. (DICHLOROPHENYL)TRICHLOROSILANE is decomposed by moisture or water to hydrochloric acid with evolution of heat. (DICHLOROPHENYL)TRICHLOROSILANE is corrosive to metals and tissue. (DICHLOROPHENYL)TRICHLOROSILANE is used as an intermediate for silicones.
Chlorosilanes, such as (DICHLOROPHENYL)TRICHLOROSILANE, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases.
Contact causes burns to skin and eyes. If inhaled, it may be harmful. Fire may produce irritating or poisonous gases. The compound is highly toxic by inhalation and is a strong irritant to the skin and eyes.
(DICHLOROPHENYL)TRICHLOROSILANE may burn but does not ignite readily. Flammable/poisonous gases may accumulate in tanks and hopper cars. (DICHLOROPHENYL)TRICHLOROSILANE may ignite combustibles (wood, paper, oil, etc.). The compound is a slight fire hazard when exposed to heat or flame. (DICHLOROPHENYL)TRICHLOROSILANE is decomposed by moisture or water to hydrochloric acid with the evolution of heat.
Poison by ingestion,
inhalation, subcutaneous, and intraperitoneal
routes. Corrosive to the eyes, skin, and
mucous membranes. On contact with
moisture it releases corrosive HCl.
Combustible when exposed to heat or
flame. When heated to decomposition it
emits toxic fumes of Cl-. See also
CHLOROSILANES.
This material is used in silicone
polymer manufacture.
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water ormilk. Do not induce vomiting. Medical observation isrecommended for 24-48 h after breathing overexposure, aspulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consideradministering a corticosteroid spray.
(1) Color Code—White: Corrosive or ContactHazard; Store separately in a corrosion-resistant location.(2) Color Code—Blue: Health Hazard/Poison: Store in asecure poison location. Prior to working with this chemicalyou should be trained on its proper handling and storage.Dichlorophenyl trichloro-silane should be stored to avoidcontact with moisture or with combustible materials, suchas wood, paper, and oil.
UN2987 Chlorosilanes, corrosive, n.o.s, Hazard
class: 8; Labels: 8-Corrosive material.
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, and epoxides. Chlorosilanes react
vigorously with bases and both organic and inorganic acids
generating toxic and/or flammable gases. Chlorosilanes
react with water, moist air, or steam to produce heat and
toxic, corrosive fumes of hydrogen chloride. They may also
produce flammable gaseous hydrogen. Contact with ammonia may form a self-igniting material. Attacks some metals
in the presence of moisture
