Chemical Properties
Colorless liquid that fumes strongly in
moist air.
General Description
Ethylphenyldichlorosilane is a colorless liquid with a pungent odor. Ethylphenyldichlorosilane is decomposed by water to hydrochloric acid with evolution of heat. Ethylphenyldichlorosilane is corrosive to metals and tissue.
Air & Water Reactions
Reacts vigorously with water to form hydrogen chloride(hydrochloric acid)
Reactivity Profile
Chlorosilanes, such as Ethylphenyldichlorosilane, 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. Special Hazards of Combustion Products: Toxic hydrogen chloride and phosgene fumes may be formed.
Health Hazard
Inhalation irritates nose and throat. Contact with liquid causes severe burns of eyes and skin. Ingestion causes severe burns of mouth and stomach.
Hazard
Toxic by inhalation and ingestion, strong
irritant to eyes and skin.
Potential Exposure
Used in the manufacture of silicone
polymers
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
30 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 do not induce vomiting. 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
Shipping
UN2435 Ethylphenyldichlorosilane, Hazard
class: 8; Labels: 8-Corrosive material.
Incompatibilities
A strong reducing agent. 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. Attacks human tissue and metals in the
presence of moisture
