EC number: 223-267-7
CAS number: 3794-83-0
Vapour pressure: 7.7E-11 Pa at 25°C
A predicted vapour
pressure value of 7.7E-11 Pa
at 25°C was obtained for the substance using an accepted calculation
method (MPBPVP program, USEPA/Syracuse Research, v1.43). The result is
considered to be a reliable indication of involatile nature of the
In a disregarded study, measured
vapour pressure of 210 Pa at 20°C was obtained for the substance using
the dynamic method. The submission substance is a fully
neutralised phosphonic acid salt, involatile and with a melting
temperature of >500°C. The measured result might be influenced
by presence of volatile impurities and as such the result is disregarded
and not used for assessment purposes.
