NFPA 704 MHazard Identification (based on NFPA-704 M RatingSystem): Health 3, Flammability 2, Reactivity 2 . Reactswith water.

Chemical properties

Colorless to yellow liquid. Readily hydrolyzed by moisture with the liberation of hydrogen chloride. Combustible.

Chemical properties

Amyl trichlorosilane is a colorless to yellowish liquid with a sharp acrid odor (like hydrochloric acid).

The Uses of Amyltrichlorosilane (mixed isomers)(Pentyltrichlorosilane)

Intermediate for silicones.

General Description

A colorless to yellow liquid with a pungent odor. Amyltrichlorosilane (mixed isomers)(Pentyltrichlorosilane) is combustible and has a flash point of 145°F. Corrosive to metals and tissue.

Reactivity Profile

Chlorosilanes, such as Amyltrichlorosilane (mixed isomers)(Pentyltrichlorosilane), 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.

Hazard

Toxic and corrosive.

Health Hazard

Inhalation causes irritation of mucous membrane. Contact of liquid with eyes or skin causes severe burns, and ingestion causes severe burns of mouth and stomach.

Safety Profile

Moderately toxic by ingestion and skin contact. Mildly toxic by inhalation. A corrosive irritant to the eyes, skin, and mucous membranes. When heated to decomposition it emits toxic fumes of Cl-. See also CHLOROSILANES

Potential Exposure

It is used to make silicones.

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 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 ContactHazard; Store separately in a corrosion-resistant location.Prior to working with this chemical you should be trainedon its proper handling and storage. Store in tightly closedcontainers in a cool, well-ventilated area. Metal containersinvolving the transfer of this chemical should be groundedand bonded. Where possible, automatically pump liquidfrom drums or other storage containers to process containers. Drums must be equipped with self-closing valves,pressure vacuum bungs, and flame arresters. Use only nonsparking tools and equipment, especially when openingand closing containers of this chemical. Sources of ignition, such as smoking and open flames, are prohibitedwhere this chemical is used, handled, or stored in a mannerthat could create a potential fire or explosion hazard.

Shipping

UN1728 Amyltrichlorosilane, Hazard class: 8; Labels: 8-Corrosive material.

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 generating toxic and/or flammable gases. Chlorosilanes react with water, moist air, or steam releasing heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous hydrogen. Attacks metals in the presence of moisture.
