Description of key information

Henry's Law constant was calculated using experimental values for vapour pressure and water solubility. The value determined is 0.870696 Pa m3/mole at 20°C (equivalent to Log H value of -0.06013). 
The resulting value indicates that dimethyl terephthalate is unlikely to partition from aqueous systems to the atmosphere.
