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 chlorine atoms and two benzyl groups, making it a dichlorosilane derivative. With a molecular weight of 281.2 g/mol, it belongs to the family of organosilicon compounds used primarily as intermediates in chemical synthesis and materials science applications.

Dibenzyl(dichloro)silane is typically a colorless to pale yellow liquid at room temperature with a characteristic sharp odor. As an organosilicon compound containing chlorine substituents, it is moisture-sensitive and may react with water to form hydrochloric acid and silanols. The compound is generally soluble in organic solvents such as toluene, dichloromethane, and other non-polar to moderately polar solvents, but insoluble in water due to its hydrophobic benzyl groups.

Dibenzyl(dichloro)silane serves as a valuable intermediate in organosilicon chemistry and materials synthesis. It is primarily used for the preparation of specialized silicone polymers, surface modification agents, and coupling agents. The compound finds applications in the production of functional siloxanes, cross-linking agents for polymer systems, and as a precursor for silicon-containing materials in electronics and advanced materials manufacturing. Its dual benzyl functionality makes it particularly useful for creating aromatic-containing silicon compounds.

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. The compound is moisture-sensitive and may release HCl upon contact with water, so dry conditions should be maintained. Avoid contact with skin, eyes, and clothing, and ensure proper grounding when transferring to prevent static discharge.

Dibenzyl(dichloro)silane should be stored in a cool, dry place away from moisture and water sources to prevent hydrolysis reactions. Keep containers tightly sealed in their original packaging under inert atmosphere if possible. Store away from incompatible materials such as strong bases, alcohols, and amines. The storage area should be well-ventilated and equipped with appropriate spill containment measures. Maintain storage temperatures according to supplier specifications to ensure product stability and prevent degradation.

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

Dibenzyl(dichloro)silane must be disposed of as hazardous chemical waste according to local and national regulations. Contact licensed waste disposal companies for proper handling and treatment. Small quantities can be carefully neutralized by qualified personnel using appropriate alcohols under controlled conditions, but this should only be done by experienced chemists. Never dispose of this compound down drains or in regular waste. Consult local environmental authorities for specific disposal requirements and approved waste treatment facilities in your area.

Dibenzyl(dichloro)silane is classified under ADR Class 8 (Corrosive substances), Packing Group II, indicating it requires specific transport precautions. The compound must be packaged in UN-approved containers suitable for corrosive materials and properly labeled with appropriate hazard markings. Transport vehicles must comply with ADR regulations for Class 8 substances, including proper placarding and documentation. Only authorized carriers experienced in handling corrosive chemicals should transport this material, following all applicable dangerous goods regulations.

Dibenzyl(dichloro)silane is subject to standard chemical regulations including REACH registration requirements in the European Union for commercial use. The compound is not currently listed as a Substance of Very High Concern (SVHC) under REACH. Users must comply with CLP regulation requirements for classification, labeling, and packaging. Industrial users should ensure proper risk assessments and implement appropriate risk management measures. Always check current regulatory status as requirements may change over time.
