Dibenzyl(dichloro)silane

Dibenzyl(dichloro)silane is an organosilicon compound with the molecular formula C14H14Cl2Si and CAS number 18414-36-3. This chemical features a silicon atom bonded to two benzyl groups and two chlorine atoms, giving it a molecular weight of 281.2 g/mol. It belongs to the family of chlorosilanes, which are important intermediates in organosilicon chemistry and materials science applications.

Dibenzyl(dichloro)silane is typically a liquid at room temperature with characteristic organosilicon properties. Like other chlorosilanes, it is moisture-sensitive and readily hydrolyzes in the presence of water, releasing hydrogen chloride. The compound is generally soluble in organic solvents but reacts with protic solvents. Its relatively high molecular weight of 281.2 g/mol and aromatic benzyl groups influence its physical properties and reactivity patterns.

Dibenzyl(dichloro)silane is primarily used as an intermediate in organosilicon synthesis and materials science applications. It serves as a precursor for preparing various organosilicon polymers, silicone materials, and surface modification agents. The compound is valuable in research and development for creating specialized silicone compounds with specific properties. Its benzyl groups make it particularly useful for introducing aromatic functionality into silicone-based materials and coatings.

Dibenzyl(dichloro)silane should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in a well-ventilated area or under a fume hood to avoid inhalation of vapors. As a moisture-sensitive chlorosilane, keep containers tightly sealed and avoid contact with water. Use proper grounding procedures when transferring the material to prevent static discharge.

Dibenzyl(dichloro)silane must be stored in a cool, dry place away from moisture and humidity to prevent hydrolysis reactions. Keep containers tightly sealed in their original packaging and store in a well-ventilated area. Avoid storage near incompatible materials such as strong bases, alcohols, and water. The storage area should be equipped with appropriate spill containment measures and maintained at stable temperatures to preserve product integrity.

In case of skin contact with dibenzyl(dichloro)silane, immediately remove contaminated clothing and rinse the affected area with plenty of water for at least 15 minutes. For eye contact, flush thoroughly with clean water and seek medical attention. If inhaled, move the person to fresh air and seek medical advice if symptoms persist. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult safety data sheets for specific guidance.

Dibenzyl(dichloro)silane waste must be disposed of according to local, national, and international hazardous waste regulations. The material should not be released into the environment and requires proper treatment at licensed waste disposal facilities. Small quantities can be carefully hydrolyzed under controlled conditions by qualified personnel, but this should only be done following proper safety protocols. Contact authorized waste management companies for proper disposal procedures and documentation.

Dibenzyl(dichloro)silane is classified under ADR transport regulations as Class 8 (corrosive substances), Packing Group II. This classification requires specific packaging, labeling, and documentation for road transport within Europe. Containers must meet UN specification requirements and display appropriate hazard labels. Transport vehicles need proper placarding and drivers require ADR certification. Ensure compliance with all applicable dangerous goods regulations during shipment.

Dibenzyl(dichloro)silane is subject to standard chemical regulations including REACH registration requirements in Europe for commercial use. While not currently listed as a Substance of Very High Concern (SVHC), it must comply with CLP regulation requirements for classification, labeling, and packaging. Users should maintain safety data sheets and follow workplace exposure guidelines. Regular monitoring of regulatory updates is recommended as chemical regulations continue to evolve.
