Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Terephthalic acid is a solid.  It sublimes at 402-404 degrees C at atmospheric pressure, without undergoing a transition to the liquid phase.  Its boiling point cannot therefore be determined except under artificial physical conditions that have no practical relevance.  A study to determine the boiling point of terephthalic acid is therefore scientifically unjustified.  

Key value for chemical safety assessment
