Description of key information

Tertiary butyl alcohol was estimated to lose the first proton (HL/H+L) at a pKa of 19.2 at 25 °C.
The dissociation constant for Poly[oxy(methyl-1,2-ethanediyl)], alpha-hydro-omega-hydroxy is estimated to be pKa1 of 14.43 (pKa1) and 14.41 (pKa2).

Key value for chemical safety assessment

pKa at 20°C:
