| | Cyclohexyltrichlorosilane Usage And Synthesis |
| Description | Cyclohexyl trichlorosilane is a colorless topale yellow liquid. Molecular weight=217.6; Boilingpoint=208℃; Flash point=91℃. Hazard Identification(based on NFPA-704 M Rating System): Health 2,Flammability 2, Reactivity 1 . Insoluble in water; reactive. | | Chemical Properties | Cyclohexyl trichlorosilane is a colorless to
pale yellow liquid. | | Chemical Properties | CLEAR COLOURLESS LIQUID | | General Description | A colorless to pale yellow liquid with a pungent odor. Flash point 185°F. Corrosive to metals and tissue. | | Reactivity Profile | Chlorosilanes, such as Cyclohexyltrichlorosilane, 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 | TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Contact with molten substance may cause severe burns to skin and eyes. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. | | Fire Hazard | Combustible material: may burn but does not ignite readily. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. | | Safety Profile | A highly toxic and
corrosive material. When heated to
decomposition it emits toxic fumes of Cl-.
See also CHLOROSILANES. | | Potential Exposure | Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explo-
sions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides. Chlorosilanes react vigor-
ously with bases and both organic and inorganic acids gen-
erating 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 pro-
duce flammable gaseous hydrogen. Attacks metals in the
presence of moisture. | | First aid | If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least 15 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 | | storage | Color Code—White: Corrosive or Contact Hazard;Store separately in a corrosion-resistant location. Prior toworking with this chemical you should be trained on itsproper handling and storage. Store in tightly closed containers in a cool, well-ventilated area away from water, steam,and moisture; and away from combustible materials, suchas wood, oil, and paper; and incompatible materials listedabove. Metal containers involving the transfer of this chemical should be grounded and bonded. Where possible, automatically pump liquid from drums or other storagecontainers to process containers. Drums must be equippedwith self-closing valves, pressure vacuum bungs, and flamearresters. Use only nonsparking tools and equipment, especially when opening and closing containers of this chemical. Sources of ignition, such as smoking and open flames,are prohibited where this chemical is used, handled, orstored in a manner that could create a potential fire orexplosion hazard. Wherever this chemical is used, handled,manufactured, or stored, use explosion-proof electricalequipment and fittings. | | Shipping | UN1763 Cyclohexyltrichlorosilane, Hazard
