Additional information

There are several published values available from handbooks or internet databases, all assessed with reliability 2, in the range of 131 -138°C, three of them confirmed to be measured at atmospheric pressure. Hence, it can be concluded that the other values were also derived at atmospheric pressure, leading to the implication that the real value can be taken as 131°C at 760 Torr.

Further values are available in the temperature range of 68 -100°C, measured at a pressure of 5 -65 Torr. Since these low values are generally less relevant for risk assessment, where the usual atmospheric pressure of 1.013 bar is relevant, these values can so be regarded to a lesser extent, which is also applicable for the two values derived from QSAR estimation. Hence, 137°C at 760 Torr are left as the proper value for further risk assessment.
