Description of key information
The vapour pressure of two representative molecules of Amines, N-C12-18-alkylbis(trimethylene)tri, reaction products with N-C-12-18-alkyltrimethylenediamines and formic acid was calculated to be 8 x 10^-5 Pa and 2 x 10^-2 Pa at 25°C, study "CRRA 2010/K2 KS/Theoretical estimation of vapour pressure"
Key value for chemical safety assessment
- Vapour pressure:
- 0.02 Pa
- at the temperature of:
- 25 °C
Additional information
The vapor pressure two selected molecules contained in Amines, N-C12-18-alkylbis(trimethylene)tri, reaction products with N-C-12-18-alkyltrimethylenediamines and formic acid was calculated using SPARC and MPBPVP v1.42 (EPIwin) as recommended in the Technical Guidance document for preparing the chemical safety assessment. Chap R.7 : Endpoint specific Guidance. The molecules are N-[3-(dodecylamino) propyl]formamide (smiles code: [H]C(=O)NCCCNCCCCCCCCCCCC )and 1-dodecyl-1,4,5,6-tetrahydropyrimidine (smiles code: CCCCCCCCCCCCN1CCCN=C1 |c:16| ).
The estimations of the vapor pressure of these two selected molecules lead to a range of of 8 x 10^-5 Pa and 2 x 10^-2 Pa at 25°C. Because of the relative weakness of the models, uncertainty can be important.
