Description of key information

Key value for chemical safety assessment

Vapour pressure:
5.7 Pa
at the temperature of:
20 °C

Additional information

The vapour pressure has been determined in compliance with the EC A4 method, the OECD Guideline No 104 and the GLP. The method used in this study is the Knudsen cell effusion method coupled to a micro-balance.

The major part of the test item was evaporated after the experimentation. No degradation of the test item was observed.

The vapour pressure of O-Diethoxybenzene extrapolated at 20°C is P = 5.7 Pa.

The vapour pressure of O-Diethoxybenzene extrapolated at 25°C is P = 13 Pa.

The volatility of the test item at 20°C is H= 1.5 Pa.m3.mol-1(calculated value).

Based on these results, the test item has a low volatility.
