Octyltrichlorosilane Chemical Properties,Usage,Production

Chemical Properties

CLEAR COLOURLESS TO LIGHT YELLOW LIQUID

Uses

OTS functionalized magnesium oxide (MnO₂)/aluminium oxide (Al₂O₃) surface can be used as a catalyst in the decomposition of ozone (O₃) and nitrogen dioxide (NO₂). OTS can also be used for the surface modification of silicon oxide (SiO₂), used in the fabrication of pentacene organic field effect transistors (OFETs). OTS functionalized wafers can be coated on enhanced green fluorescent protein (GFP) and anchor peptides based films to determine the thickness of the films.

General Description

N-Octyltrichlorosilane is a colorless liquid with a pungent odor. It is decomposed by water to hydrochloric acid with evolution of heat. Octyltrichlorosilane is corrosive to metals and tissue and used as an intermediate for silicones.

Reactivity Profile

Chlorosilanes, such as N-OCTYLTRICHLOROSILANE, 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.

Flammability and Explosibility

Not classified

Safety Profile

A corrosive irritant to skin, eyes, and mucous membranes. Will react with water or steam to produce toxic and corrosive fumes. When heated to decomposition it emits toxic fumes of Cl-. See also CHLOROSILANES.

Synthesis

In a 25 ml oven dried stainless steel tube, 0.22 g (0.67 mmol) of benzyltributylphosphonium chloride, 1.00 g (6.73 mmol) of 1-chlorooctane, and 2.71 g (20.0 mmol) of trichlorosilane were added under a dry nitrogen atmosphere. After sealing the cylinder with a cap, the reactor was maintained at 170°C. for 2 hrs. The resulting mixture was distilled to yield 1.45 g of n-octyltrichlorosilane (yield; 87%). n-Octyltrichlorosilane, 1.45 g, 87% yield MS (70eV EI) m/z (relative intensity): 250(1), 248(3), 246(4), 179(12), 177(35), 175 (34), 135(53), 133(54), 85(100), 71(57), 57(98).

Purification Methods

Purify the silane by repeated fractionation using a 15-20 theoretical plate glass column packed with glass helices. This can be done more efficiently using a spinning band column. The purity can be checked by analysing for Cl (ca 0.5-1g of sample is dissolved in 25mL of MeOH, diluted with H2O and titrated with standard alkali). It is moisture sensitive.
