29319090 | [Safety Profile]
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-. | [Hazardous Substances Data]
7521-80-4(Hazardous Substances Data) |
| Hazard Information | Back Directory | [General Description]
A colorless liquid with a pungent odor. Flash point 126°F. Corrosive to metals and skin. Used to make various silicon containing compounds. | [Reactivity Profile]
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. | [Health Hazard]
Inhalation of vapor irritates upper respiratory system. Contact of liquid with eyes or skin causes severe burns. Ingestion causes burns of mouth and stomach. | [Potential Exposure]
This is a raw material for silicone
resin productio | [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. If victim is conscious, administer water or milk. Do not induce vomiting.
Medical observation is recommended for 24 to 48 hours
after breathing overexposure, as pulmonary edema may be
delayed. As first aid for pulmonary edema, a doctor or
authorized paramedic may consider administering a drug
or other inhalation th | [Shipping]
UN1747 Butyl trichlorosilane, Hazard class: 8;
Labels: 8—Corrosive material, 3—Flammable liquid | [Incompatibilities]
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 | [Description]
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. | [Chemical Properties]
Butyl trichlorosilane is a colorless liquid.
| [Uses]
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. | [storage]
(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. |
