Description of key information
Bis-(2-ethylhexyl) peroxydicarbonate is moderately soluble (100-1000 mg/L, 24 hours equilibration). Hydrolysis occurs
rapidly; the data show that at any time intact peroxide is present at significantly lower concentration than the major breakdown product.
At pH 7, 1 h reaction time, peroxide was present at approx. 1 mg/L, compared to 6.6 mg/L (mean value) 2-ethyl-1-hexanol. In the further course of the experiment the concentration of degradation product increased whereas peroxide was no longer detectable at 24 h.
These findings support the conclusion that the hydrolytical half-life (DT50) of bis-(2-ethylhexyl) peroxydicarbonate at 5 °C is less than 1 hour, although this could not be determined by kinetic calculations.
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 1 h
- at the temperature of:
- 5 °C
Additional information
Hydrolytical activity of the test item was determined at pH 4.0 and 7.0. Experimental investigations at pH 9 were not feasible due to insufficient accuracy of the analytical method (possible reaction between the target molecule and borate). In the course of the hydrolysis experiment, the following reaction products were detected:
2-ethylhexanoic acid (CAS No. 149-57-5) amounting to maximally 3.2 %, 2-ethyl-1-hexanol (CAS No. 104-76-7, main transformation product amounting to approximately 96 %), 2-heptanone (CAS No. 110-43-0) amounting to maximally 3.9 %, and 3-heptanol (CAS No. 589-82-2) amounting to maximally 1.4 %. Only the main degradation product 2-ethyl-1-hexanol was quantified against an external standard. However, determination of the relative amounts of the minor products is considered to be reliable due to the properties of the FID detector used.
Hydrolysis of bis-(2-ethylhexyl) peroxydicarbonate takes place instantly. From the data it can be concluded that bis-(2-ethylhexyl) peroxydicarbonate is moderately soluble (100-1000 mg/L, 24 h) but hydrolysis takes place rapidly and the intact peroxide is not detectable in aqueous solutions after 24 hours reaction time. The hydrolytical half-life (DT50) of bis-(2-ethylhexyl) peroxydicarbonate is less than 1 hour at 5 °C.
