Cyclohexyl-dimethoxy-methylsilane

Cyclohexyl-dimethoxy-methylsilane is an organosilicon compound with the molecular formula C9H20O2Si and CAS number 17865-32-6. This silane features a cyclohexyl group attached to a silicon atom along with two methoxy groups and one methyl group. With a molecular weight of 188.34 g/mol, it belongs to the family of functional silanes used primarily as coupling agents and surface modifiers in various industrial applications.

Cyclohexyl-dimethoxy-methylsilane is typically a clear to slightly yellow liquid at room temperature with a characteristic silane odor. As an alkoxy silane, it is hydrolytically sensitive and reacts with moisture to form silanols and alcohols. The compound has moderate volatility due to its molecular structure and is soluble in most organic solvents while being reactive with water and alcohols.

Cyclohexyl-dimethoxy-methylsilane is primarily used as a coupling agent and surface modifier in industrial applications. It serves to improve adhesion between organic polymers and inorganic substrates such as glass, metals, and fillers. The compound is commonly employed in composite materials, sealants, adhesives, and coatings where enhanced interfacial bonding is required. It also finds use in surface treatments for improving material compatibility.

Cyclohexyl-dimethoxy-methylsilane should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing due to its Skin Irritant 2 classification. Work in well-ventilated areas or use local exhaust ventilation to minimize inhalation exposure. Avoid direct skin and eye contact. Use non-sparking tools and equipment when handling, and ensure proper grounding to prevent static electricity buildup.

Cyclohexyl-dimethoxy-methylsilane should be stored in tightly sealed containers in a cool, dry place away from moisture and humidity. Keep containers in a well-ventilated area away from heat sources and incompatible materials. Store at ambient temperature and protect from direct sunlight. Due to its hydrolytic sensitivity, maintain an inert atmosphere when possible and check container integrity regularly to prevent moisture ingress.

In case of skin contact with cyclohexyl-dimethoxy-methylsilane, 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 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical advice if respiratory irritation occurs. Do not induce vomiting if ingested.

Cyclohexyl-dimethoxy-methylsilane waste must be disposed of according to local and national environmental regulations. The compound should not be released into waterways due to its Aquatic Chronic 2 classification. Collect waste in appropriate containers and arrange disposal through licensed waste management companies. Small quantities can be neutralized through controlled hydrolysis before disposal, following proper environmental guidelines and permits.

Cyclohexyl-dimethoxy-methylsilane is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. It requires appropriate packaging according to ADR regulations and proper labeling with hazard pictograms GHS07 and GHS09. Transport vehicles must comply with ADR requirements for Class 9 materials. Ensure containers are properly sealed and secured to prevent leakage during transport.

Cyclohexyl-dimethoxy-methylsilane is subject to REACH regulation in Europe and must comply with CLP classification requirements. It is classified as Skin Irritant 2 and Aquatic Chronic 2 under CLP with the signal word 'Warning'. The substance is not currently listed as SVHC (Substance of Very High Concern). Users must follow safety data sheet requirements and ensure proper risk assessment and management measures are implemented.
