Reference
Endpoint:
vapour pressure
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
QSAR prediction
Principles of method if other than guideline:
The result was obtained using an appropriate QSAR method (see attached QMRF and QPRF for details).
Temp.:
25 °C
Vapour pressure:
< 0 Pa
Remarks on result:
other: Since the vapour pressure is outside the applicability domain (the episuite vapour pressure is too low), the value is taken as “less than the upper limit" for all components.
Conclusions:
A vapour pressure < 2.8E-04 Pa at 25°C was obtained using an accepted calculation method. The result is considered to be reliable.

Key value for chemical safety assessment

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

Additional information

Vapour pressure values (Pa at 25°C) for the individual components (single ionised salt form) were determined using an appropriate calculation method which is considered to be reliable:

N-[3-(trihydroxysilyl)propyl]ethylenediamine monohydrochloride: < 2.8E-04 Pa

(2-aminoethyl)[(4-vinylphenyl)methyl][3-(trihydroxysilyl)propyl] amine hydrochloride: < 2.8E-04 Pa

N-[3-(trihydroxysilyl)propyl]-N'-(4-vinylbenzyl)-1,2-ethanediamine hydrochloride: < 2.8E-04 Pa

N-[3-(trihydroxysilyl)propyl]-N,N'-di(4-vinylbenzyl)-1,2- ethanediamine hydrochloride: < 2.8E-04 Pa

N-[3-(trihydroxysilyl)propyl]-N’,N'-di(4-vinylbenzyl)-1,2- ethanediamine hydrochloride: < 2.8E-04 Pa

N-[3-(trihydroxysilyl)propyl]-N,N’,N'-tri(vinylbenzyl)-1,2- ethanediamine hydrochloride: < 2.8E-04 Pa

Since the vapour pressure is outside the applicability domain (the episuite vapour pressure is too low), the value is taken as “less than the upper limit" for all components.
