Description of key information

According to theoretical considerations based on chemical structure, terephthalic acid does not to possess explosive or oxidising properties.  Terephthalic acid is unlikely to undergo rapid decomposition accompanied by the evolution of gases or release of heat and therefore does not present a risk of explosion.  

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

Based on chemical structure, terephthalic acid does not contain any of the groups associated with explosive properties. The molecular weight of TPA is 166 and the calculated oxygen balance value is -145%. Terephthalic acid is not classified for transport as an explosive or oxidising substance. Terephthalic acid is predicted not to possess explosive or oxidising properties. TPA is unlikely to undergo rapid decomposition accompanied by the evolution of gases or release of heat and therefore does not present a risk of explosion.
