Trichloro(pentyl)silane

Trichloro(pentyl)silane is an organosilicon compound with the molecular formula C5H11Cl3Si and CAS number 107-72-2. This chemical features a pentyl group attached to a silicon atom bonded to three chlorine atoms. With a molecular weight of 205.6 g/mol, it belongs to the family of chlorosilanes, which are important intermediates in silicon chemistry and materials science applications.

Trichloro(pentyl)silane is typically a colorless to pale yellow liquid at room temperature with a pungent, irritating odor characteristic of chlorosilanes. It readily hydrolyzes in the presence of moisture, releasing hydrogen chloride gas. The compound is immiscible with water due to its hydrolytic nature but is soluble in organic solvents such as hydrocarbons and ethers.

Trichloro(pentyl)silane is primarily used as a coupling agent and surface modifier in the production of silicone polymers and resins. It serves as an intermediate in the synthesis of specialty silicones, particularly for applications requiring enhanced adhesion between organic and inorganic materials. The compound is also utilized in the preparation of hydrophobic surface treatments and as a precursor for silicon-based coatings.

Trichloro(pentyl)silane should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation of vapors. Avoid contact with moisture and water, as this leads to the formation of corrosive hydrogen chloride gas. Use non-sparking tools and ground equipment properly.

Trichloro(pentyl)silane must be stored in tightly sealed containers in a cool, dry place away from moisture and humidity. Storage areas should be well-ventilated and protected from heat sources and direct sunlight. Keep away from water, alcohols, and strong bases which can cause violent reactions. Use corrosion-resistant storage materials and ensure containers are properly labeled and dated.

Trichloro(pentyl)silane contact requires immediate action: for skin contact, remove contaminated clothing and flush affected area with plenty of water for at least 15 minutes. In case of eye contact, rinse thoroughly with water and seek medical attention immediately. If inhaled, move the person to fresh air and provide oxygen if breathing is difficult. Seek medical attention for all exposure incidents.

Trichloro(pentyl)silane disposal must comply with local and national hazardous waste regulations. The compound should be treated as hazardous waste and disposed of through licensed waste management facilities. Small quantities can be carefully hydrolyzed under controlled conditions to neutralize the chlorosilane, but this should only be performed by trained personnel with proper safety equipment and environmental controls in place.

Trichloro(pentyl)silane is classified as ADR Class 8 (corrosive substances) with Packing Group II, indicating moderate danger level. Transport requires appropriate corrosive substance packaging and labeling according to dangerous goods regulations. Vehicles must carry proper documentation, emergency response information, and drivers need hazardous materials training. Ensure packages are leak-proof and properly secured during transit.

Trichloro(pentyl)silane is subject to REACH regulation requiring registration for manufacture or import above one tonne per year in the EU. It must be classified and labeled according to CLP regulation, though specific harmonized classification may not be established. The substance is not currently identified as a Substance of Very High Concern (SVHC), but users must comply with standard chemical safety requirements.
