EC number: 260-135-8
CAS number: 56375-79-2
both the first and second analysis of the test substance, the weight
losses of the test substance at 110°C, 120°C, 130°C and 140°C were lower
than the weight losses of hexachlorobenzene at the same temperatures.
From this it was concluded that vapour pressure of the substance at 20°C
(25°C) is lower than the vapour pressure of hexachlorobenzene at 20°C
Using the isothermal thermogravimetric effusion method, the vapour pressure of MTBAC at 25°C has been determined as < 7.0E-03 Pa. The vapour pressure of MTBAC at 20°C has been determined as < 1.5E-03 Pa. The study was performed in accordance with EC A.4, OECD 104 and EPA OPPTS 830.7950 guidelines and in compliance with GLP.
Key value for CSA: < 0.007 Pa at 25°C
