Description of key information

1,1,1,2-tetrafluoroethane (HFC 134a) will not dissociate into a conjugate base and proton or conjugate acid and hydroxyl ion.

Key value for chemical safety assessment

Additional information

According to REACH Annex IX, 7.16, Column 2, the study does not need to be done if scientifically not possible. 1,1,1,2-tetrafluoroethane (HFC 134a) will not dissociate into a conjugate base and proton or conjugate acid and hydroxyl ion. Therefore it is not possible to measure a dissociation constant.
