Description of key information

The vapour pressure of HMTBA was determined by QSAR EPIWIN to be 0.0353 Pa at 25°C.

Key value for chemical safety assessment

Vapour pressure:
0.035 Pa
at the temperature of:
25 °C

Additional information

The influence on vapour pressure measurements of potential impurities more volatile than water, and of water itself, that are present in the substance placed on the market, make the laboratory measurement questionable from a metrology standpoint. This justifies that the vapour pressure of HMTBA be evaluated by means of a QSAR.

The vapour pressure of HMTBA was determined by QSAR EPIWIN to be 0.0353 Pa at 25°C.
