Vapour pressure:
0
Remarks on result:
not measured/tested
Remarks:
calculated by QSAR program MPBPWIN
Conclusions:
Based on the calculations by QSAR program MPBPWIN (version 1.43) the vapour pressure of Dimethylbis[2-[(1-oxohexadecyl)oxy]ethyl]ammonium chloride was estimated to be 2.3· 10^-16 Pa.
Therefore , the vapour pressure needs not to be determined experimentally.
