EC number: 270-128-1
CAS number: 68411-46-1
The solubilities at 20°C and at pH 5.6 were found as
1.6 mg/l with a loading rate of ca. 1 g/L
2.3 mg/l with a loading rate of ca. 10 g/L
Additionally, the estimated values of the individual
constituents are as follows:
Group A= 0.014 mg/L
Group B= 1.544E-4 mg/L
Group C= 1.939E-6 mg/L
Group D= 1.167 mg/L
The test item is a mixture of compounds. Every
constituent contributes to a different degree to overall solubility,
depending on its own individual solubility and its mass fraction in the
test item. Thus, analytical results depend on the proportions of test
item and water used in the experiment.
The determinations were carried out by flask method in
accordance with the OECD Guideline 105. Although the water solubility is
<10 mg/L, the flask method was carried out because tests according to
the column elution method had shown that the different constituents have
different solubilities in water. The quantification was analyzed by TOC.
In addition, the solubilities of the individual
constituents have been generated using recommended WSKOW (v1.42) module
of software EPI Suite v.4.11.
