Description of key information

The calculated boiling range of α,α,α',α'-tetramethyl-m-xylene-α,α'-diol is 275.6-315.6°C at 760 Torr.

Key value for chemical safety assessment

Additional information

Calculation is not considering the possibility of degradation, which often occurs with organic compounds.

Since a,a,a',a'-tetramethyl-m-xylene-a,a'-diol is a transported intermediate, no testing is required.

The two models calculate similar boiling points.
