Description of key information

Basing on the chemical structure of 1,2-dichloro-1-[difluoro(trifluoromethoxy)methoxy]-1,2,2-trifluoroethane molecule, Hydrolysis is not expected to occur at any pH in the range from 4 to 11.

Key value for chemical safety assessment

Additional information

Hydrolysis is not expected to occur basing on the chemical structure of 1,2-dichloro-1-[difluoro(trifluoromethoxy)methoxy]-1,2,2-trifluoroethane molecule.

1,2-dichloro-1-[difluoro(trifluoromethoxy)methoxy]-1,2,2-trifluoroethane does  not contain any functional group associated with hydrolysis properties  at relevant environmental conditions and therefore is not expected to hydrolyze. Particularly the Carbon-fluorine bond is the strongest bond in organic chemistry. Substitution of hydrogen atoms with fluorine results in increased bond strengths for both C-F and adjacent C-C bonds over the corresponding hydrocarbon and would increase the resistence to hydrolysis . Therefore, hydrolysis is not a relevant degradation mechanisms for this substance.

Moreover the water solubility of the substance 1,2-dichloro-1-[difluoro(trifluoromethoxy)methoxy]-1,2,2-trifluoroethane is very low and it is not expected to change ranging the pH from 4 to 11 as well as the reactivity with water.
