Dichlorodiphenylsilane Usage And Synthesis

Description

Diphenyl dichlorosilane is a colorless liquid. Ithas a sharp, pungent, HCl-like odor. Molecularweight= 253.21; Specific gravity = 1.22 at 25℃; Boilingpoint= 305℃; Autoignition temperature= 633.6℃; Flashpoint= 142℃ (oc). Hazard Identification (based on NFPA704 M Rating System): Health 3, Flammability 1,Reactivity 2 . Reacts with water; insoluble.

Chemical Properties

Diphenyldichlorosilane is a colorless liquid with a pungent odor. It will burn though it may require some effort to ignite. It is decomposed by water to hydrochloric acid with evolution of heat. It is corrosive to metals and tissue.

Uses

Dichlorodiphenylsilane is a silane based surface modifier, and a precursor which can be used in the synthesis of silica based materials. It is used to modify the surface by providing toughness, durability and resistance to shock. It can be used in the synthesis of a host material for the fabrication of blue phosphorescent organic light emitting diodes (OLEDs).

Reactivity Profile

Chlorosilanes, such as Dichlorodiphenylsilane, 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.

Health Hazard

Inhalation irritates mucous membranes. Contact with liquid causes severe burns of eyes and skin. Ingestion causes severe burns of mouth and stomach.

Flammability and Explosibility

Not classified

Safety Profile

A poison irritant to skin, eyes, and mucous membranes. See also CHLOROSILANES. Can react vigorously with oxidizing materials. When heated to decomposition or on contact with acid or acid fumes it emits toxic fumes of Cl-.

Potential Exposure

This material is used in the synthesisof silicone lubricants.

First aid

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 2448 h after breathing overexposure, aspulmonary edema may be delayed. As first aid for

storage

Color Code—White: Corrosive or ContactHazard; Store separately in a corrosion-resistant location.Diphenyl dichlorosilane must be stored to avoid contactwith oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates), bases, alcohols, and acids,since violent reactions occur. Store in tightly closed containers in a cool, well-ventilated area away from water,steam, and moisture because toxic and corrosive chloridegases, including hydrogen chloride, can be produced.Sources of ignition, such as smoking and open flames, areprohibited where diphenyl dichlorosilane is used, handled,or stored in a manner that could create a potential fire orexplosion hazard

Shipping

This compound requires a shipping label of“CORROSIVE.” It falls in Hazard Class 8 and PackingGroup II.

Incompatibilities

Vapors can irritate the eyes, nose,and throat. Higher levels could irritate the lungs and evenlead to pulmonary edema, a medical emergency. This cancause death. This substance is a corrosive chemical andcontact can cause severe skin burns and severe eye burnsleading to permanent damage.
