phototransformation of AAPB consisting of C8-, C10-, C12-, C14-,
C16-, and C18-fatty acids was calculated
using EPIWIN v3.11, AOPWIN v1.91. Half-lives ranging from 6.8 h
(C18 derivate) to 9 h (C8 derivate) were calculated. The results
indicate theoretically a rapid photodegradation (t1/2<10 h) of
the components (C8-C18 derivates) of AAPB. Due to the ionic
character of the compound and the low vapor pressure, however,
the occurrence of gaseous AAPB in air is expected to be
negligible and therefore the photodegradation in air is only of
information on hydrolysis is available from an EPIWIN
calculation. Hydrolysis is not to be expected under
environmental conditions: the calculated hydrolysis half-life
time (t1/2) for AAPB consisting of C8-C18 fatty acids was found
to be > 1 year.
