Butyl trichlorosilane is a colorless liquid.Molecular weight = 191.57. Boiling point = 149℃; Flashpoint =45℃ (cc); 54℃ (oc). Hazard Identification(based on NFPA-704 M Rating System): Health 3,Flammability 2, Reactivity 2 . Insoluble in water; reactsviolently.
Butyl trichlorosilane is a colorless liquid.
BTS can be coated on the glass substrate to introduce the surface alkyl, which can bind well with 2-methacryloyloxyethyl-4-azidobenzoate (MPAz) to convert hydrophophobic glass surfaces to superhydrophilic surfaces. It can functionalize zinc peroxide nanoparticle/polystyrene sulfonate (PSS) hybrid based sensors to improve the limit of detection by three-folds.
A colorless liquid with a pungent odor. Flash point 126°F. Corrosive to metals and skin. Used to make various silicon containing compounds.
N-BUTYLTRICHLOROSILANE reacts with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride and flammable butane. Can serve as a chlorination agent. Reacts vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases. Reacts with alcohols, acetone and light metals.
Inhalation of vapor irritates upper respiratory system. Contact of liquid with eyes or skin causes severe burns. Ingestion causes burns of mouth and stomach.
A corrosive poison. See
also CHLOROSILANE. Flammable liquid
when exposed to heat, flame (sparks), or
oxidizers. To fight fire, use water to blanket
fire, fog, mist, dry chemical, alcohol foam.
Reacts with water or steam to produce heat
and toxic and corrosive fumes. When heated
to decomposition it emits highly toxic fumes
of Cl-.
This is a raw material for silicone
resin productio
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least30 min, occasionally lifting upper and lower lids.Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash490 Butyl trichlorosilaneimmediately with soap and water. Seek medical attentionimmediately. If this chemical has been inhaled, removefrom exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical has beenswallowed, get medical attention. If victim is conscious,administer water or milk. Do not induce vomiting. Medicalobservation is recommended for 2448 h after breathingoverexposure, as pulmonary edema may be delayed. As firstaid for pulmonary edema, a doctor or authorized paramedicmay consider administering a corticosteroid spray.
(1) Color Code—White: Corrosive or Contact Hazard. Store separately in a corrosion-resistant location. (2) Color Code—Red: Flammability Hazard: Store in a flammable liquid storage area or approved cabinet away from ignition sources and corrosive and reactive materials. Prior to working with butyl trichlorosilane you should be trained on its proper handling and storage. Store in tightly closed containers in a cool, well-ventilated area away from moisture and incompatible materials listed above. Metal containers involving the transfer of this chemical should be grounded and bonded. Drums must be equipped with selfclosing valves, pressure vacuum bungs, and flame arresters. 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, or stored in a manner that could create a potential fire or explosion hazard.
UN1747 Butyl trichlorosilane, Hazard class: 8;
Labels: 8—Corrosive material, 3—Flammable liquid
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, epoxides. Chlorosilanes react vigorously with bases and both organic and inorganic acids genera ting 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 metals in the
presence of moisture
