Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- ABC Protocol GC-1250 Determination of Air-water Henry's Law costant for the Piperonil butoxide "
the method measures the relative concentration in the liquid phase while isothermally stripping the compound from solution by bubbling gas at a known flow rate.
-V dc/dt= PG/RT = HGC/RT
V=volume of the test solution (ml)
P=vapour pressur of the test compound (atm)
R=gas costant 0.0821 l.atm.mol^-1.k^-1
T=temperature (K)
G=flow rate of stripping gas (mL/hr)
H=Henry law costant (l.atm.mole)
C=concentration of the test compound in solution (ug/ml)
t=time (hr) - GLP compliance:
- no

Results and discussion
- Results:
- Duplicate test systems stripping 14C-piperonyl butoxide from deionized water with nitrogen gas provided en estimated value for the Henry's Law Constant of 2.35 x 10-4 1-atm/mole.
Any other information on results incl. tables
Seven data points from each test system were collected in triplicate over a
21 day period.
The mean flow rates of each system were 300 ml/min for system A and 300 ml/min
for system B for the 21 day period.
The results suggest that the substance would have little tendency to volatilize from aqueous solution under conditions similar to this study.
Applicant's summary and conclusion
- Conclusions:
- The Henry's Law Constant of 14C-piperonyl butoxide in deionized water was estimated to be less than 2.35 x 10-4 1-atm/mole.
