Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

See category for PI, PAM and their salts.

The density was calculated by using linear regression of the measured densities for PI, PDPI and PPI (y-values) versus the weight percentage of PAM (x-values) in each of the substances:

weight%       density (g/cm3)

PI              0        1.15

PDPI       46.5       1.38

PPI          63.5       1.54       

PAM       100       calculated

r2=0.97

density=0.0059*weight%+1.14

PI = 2-phenyl-2 -imidazoline, CAS 936-49 -2

PAM = benzene-1,2,4,5 -tetracarboxylic acid, CAS 89 -05 -4

PDPI = 1 mol PAM plus 2 mol PI, CAS 54553 -91 -2

PPI = 1 mol PAM plus 1 mol PI, CAS 54553 -90 -1
