Water carbonyl difluoride

Carbonyl difluoride reacts vigorously with water, to produce carbon dioxide and hydrogen fluoride [1756]. A similar reaction is observed with concentrated sulfuric acid, and it is completely absorbed by sodium hydroxide solution [1756]. Indeed, the reaction between COFj and D O at 0 C has been used to prepare DF in purities >99.5% and yields of 90% [1554], A recent ab initio study [677aa] of the mechanism and energetics of the gas-phase reaction of carbonyl difluoride with water indicates that the reaction proceeds through two transient intermediates - CFj(OH)j and FC(0)0H. The former dissociates to the latter and HF, and the FC(0)0H then dissociates into COj and HF, consistent with the overall stoicheiometry ...

CARBONYL DIFLUORIDE (353-50-4) Reacts with water or steam, producing hydrogen fluoride gas and carbon dioxide. Violent reaction with strong oxidizers, dinitrogen tetraoxide. 

Caution. Carbonyl fluoride is a water-sensitive and highly poisonous gas. It should be handled in a well-ventilated hood and in a well-constructed vacuum line. Chromium difluoride dioxide is a strong oxidizer. Organic materials must be absent.
