Carbonyl difluoride

Carbonyl difluoride is an inorganic chemical compound with the molecular formula CF2O and CAS number 353-50-4. This colorless gas has a molecular weight of 66.007 g/mol and belongs to the family of carbonyl halides. It is characterized by a carbon atom double-bonded to oxygen and single-bonded to two fluorine atoms, making it the fluorinated analog of phosgene. The compound is highly reactive due to its electrophilic carbon center.

Carbonyl difluoride is a colorless gas at room temperature with high volatility and reactivity. It has a pungent, suffocating odor and is highly soluble in organic solvents but reacts readily with water to form carbon dioxide and hydrogen fluoride. The compound has a boiling point of approximately -84°C and exhibits strong electrophilic properties. Its high reactivity makes it unstable in the presence of moisture and nucleophiles.

Carbonyl difluoride serves primarily as a chemical intermediate in organic synthesis and fluorination reactions. It is used in the production of fluorinated compounds, pharmaceuticals, and specialty chemicals. The compound acts as a carbonylation agent and is employed in research applications for introducing carbonyl groups into organic molecules. Its high reactivity makes it valuable for specialized synthetic transformations in laboratory and industrial settings.

Carbonyl difluoride requires careful handling due to its high reactivity and potential to form toxic decomposition products. Use appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Work in well-ventilated areas or under fume hoods to prevent inhalation. Avoid contact with water, moisture, and incompatible materials. Handle containers with care to prevent rupture and ensure proper grounding to avoid static discharge during transfer operations.

Carbonyl difluoride must be stored in tightly sealed, pressure-resistant containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers away from water, moisture, and incompatible materials such as strong bases and reducing agents. Storage areas should be equipped with appropriate gas detection systems and emergency ventilation. Regular inspection of containers for signs of corrosion or damage is essential for safe storage.

Immediate evacuation from the contaminated area is essential in case of carbonyl difluoride exposure. For skin contact, remove contaminated clothing and flush affected areas with copious amounts of water for at least 15 minutes. In case of inhalation, move the person to fresh air immediately and seek medical attention. For eye contact, rinse thoroughly with water. Due to potential formation of toxic decomposition products, professional medical evaluation is recommended for any exposure incident.

Carbonyl difluoride disposal must comply with local, national, and international hazardous waste regulations. The compound should never be released directly into the environment due to its reactivity and potential environmental impact. Professional waste management services specializing in reactive gases should handle disposal. Neutralization or controlled decomposition under appropriate conditions may be required. Always consult with qualified waste disposal experts and regulatory authorities before disposal.

Carbonyl difluoride is classified under ADR Class 2 (gases) for transportation purposes. Transport requires specialized pressure vessels designed for reactive gases and compliance with dangerous goods regulations. Vehicles must be properly marked and equipped with appropriate safety equipment. Drivers require hazardous materials training and certification. Emergency response information must accompany shipments, and transport should avoid extreme temperatures and rough handling that could compromise container integrity.

Carbonyl difluoride is subject to various chemical regulations including REACH registration requirements in Europe for commercial use. The compound must comply with CLP regulation for classification, labeling, and packaging. Transport is regulated under ADR/RID dangerous goods legislation. Users must maintain safety data sheets and implement appropriate risk management measures. Industrial use may require additional permits and compliance with occupational health and safety regulations depending on jurisdiction.

Carbonyl difluoride is available through specialized chemical distributors in Europe, including OYSI, which supplies high-quality chemical products to industrial and research customers. Due to its reactive nature and specialized applications, the compound typically requires custom ordering and may have specific packaging and delivery requirements. Professional chemical suppliers can provide technical support, safety documentation, and regulatory compliance assistance for carbonyl difluoride procurement.
