트리메틸클로로실란 MSDS


Chlorotrimethylsilane

트리메틸클로로실란 C화학적 특성, 용도, 생산

화학적 성질

A clear, colorless, caustic and highly flammable liquid with a pungent odour. Readily hydrolyzed with liberation of hydrogen chloride; soluble in benzene, ether and perchloroethylene.

화학적 성질

Trimethylchlorosilane is a colorless, fuming liquid. Irritating odor.

용도

Chlorotrimethylsilane is a typical Silane Blocking Agent, which can protect or deprotect functional groups selectively. It is widely used in the syntheses of drugs. It have been used in the preparation of volatile derivatives of a wide range of compounds for GC analysis, and used for silylation and as a protection group in the process of various organic synthesis.

정의

ChEBI: A silyl chloride consisting of a central silicon atom covalently bound to one chloro and three methyl groups. Chlorotrimethylsilane is a derivatisation agent used in gas chromatography/mass spectrometry applications.

일반 설명

A colorless fuming liquid with a pungent odor. Boiling point 135°F Flash point -18°F. Density 0.854 g / cm3. The vapor and liquid may cause burns. Vapors are heavier than air.

반응 프로필

Chlorotrimethylsilane reacts vigorously and exothermically with water to produce hydrogen chloride.

건강위험

Similar to other silanes. Toxicity is rated high for inhalation, ingestion and local irritation. May cause death or permanent injury after a very short exposure to small quantities.

화재위험

Violent reaction with water. Toxic and irritating hydrogen chloride and phosgene may be formed in fires. Difficult to extinguish, re-ignition may occur. Flashback along vapor trail may occur. Containers may explode in fire. Vapor may explode if ignited in enclosed area. When heated to decomposition or on contact with acids or acid fumes, chloride fumes are emitted. Reacts with surface moisture, releasing hydrogen chloride, which will corrode common metals and form flammable hydrogen gas. Avoid contact with water; Chlorotrimethylsilane readily hydrolyzes, liberating hydrochloric acid. Hazardous polymerization may not occur.

Safety Profile

Poison by ingestion and skin contact. Moderately toxic by inhalation and intraperitoneal routes. A corrosive irritant to skin, eyes, and mucous membranes. Questionable carcinogen with experimental neoplastigenic data. Mutation data reported. A flammable liquid and very dangerous fire hazard when exposed to heat or flame. Violent reaction with water or hexafluoroisopropylideneamino lithium, A preparative hazard. To fight fire, use foam, alcohol foam, fog. When heated to decomposition it emits toxic fumes of Cl-. An intermediate in the production of silicones. See also CHLOROSILASES.

잠재적 노출

Trimethylchlorosilane is used as an intermediate to make silicone products, including lubricants

응급 처치

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 24-48 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 therapy.

운송 방법

UN1298 Trimethylchlorosilane, Hazard Class: 3; Labels: 3-Flammable liquid, 8-Corrosive material.

Purification Methods

Likely impurities are other chlorinated methylsilanes and tetrachlorosilane (b 57.6o), some of which can form azeotropes. To avoid the latter, very efficient fractional distillation is required. It has been fractionated through a 12 plate glass helices-packed column with only the heart-cut material being used. It has also been fractionated through a 90cm, 19mm diameter Stedman column (p 11). Purify it by redistilling from CaH2 before use. [Sauer et al. J Am Chem Soc 70, 4254 1948, Sauer & Hadsell J Am Chem Soc 70 4258 1948, Langer et al. J Org Chem 23 50 1958, Beilstein 4 IV 4007.] FLAMMABLE and CORROSIVE.

비 호환성

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 to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous hydrogen. Attacks metals in the presence of moisture. Vigorous reaction with aluminum powder.

폐기물 처리

Do not discharge into drains or sewers. Use a licensed disposal contractor to an approved landfill. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office for guidance on acceptable disposal practices. The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material’s impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
