Conclusions:
The melting range of α,α,α',α'-tetramethyl-m-xylene-α,α'-diol is 133.8 - 137.5°C.
Executive summary:

The study was performed according to the guideline. No details were given on the method that was used.

The underlying study is not in our possession, but the studies 1999-85-5,Partition coefficient, Xu Laiwei, 2012, RS and 1999-85-5, Water solubility, Xu Laiwei, 2012, RS from the same institute are very well performed, so this indicates a reliability of 2 for this endpoint.

The melting range of α,α,α',α'-tetramethyl-m-xylene-α,α'-diol is 133.8 - 137.5°C.
