- EC Number:
- 205-528-7
- EC Name:
- Diallyl 2,2'-oxydiethyl dicarbonate
- Cas Number:
- 142-22-3
- Molecular formula:
- C12H18O7
- IUPAC Name:
- diallyl 2,2'-oxydiethyl dicarbonate

Study design
Batch equilibrium or other method
- Analytical monitoring:
- not required
- Computational methods:
- The organic-normalized sorption coefficient for soil (soil adsorption, Koc) of Diallyl-2,2`-oxydiethyl dicarbonate was determined by calculation. This calculation was performed by the computer program from US-EPA (EPIWIN software KOCWIN v2.00).
This tool uses two different models: the Salbjic molecular connectivity (MCI) method with improved correction factors and therefore taken into account more seriously as well as the traditional method which is based on the logarithmic octanol-water partition coefficient, logKow.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- For the active substance Diallyl-2,2`-oxydiethyl dicarbonate the traditional method gives a Koc of 16.9 L/kg; whereby the MCI method resulted in a value of 20.69 L/kg.
Since the multi-constituent to be registered (EC 700-483-4) contains as main ingredient 'diallyl 2,2'oxydiethyl dicarbonate', the experimental data from this substance were used in a read-across approach. - Executive summary:
The organic-normalized sorption coefficient for soil (soil adsorption, Koc) of Diallyl-2,2`-oxydiethyl dicarbonate was determined by calculation. This calculation was performed by the computer program from US-EPA (EPIWIN software KOCWIN v2.00).

For the active substanceDiallyl-2,2`-oxydiethyl dicarbonate the traditional method gives a Kocof 16.9 L/kg; whereby the MCI method resulted in a value of 20.69 L/kg. The MCI method is taken more seriously into account due to the fact, that it includes improved correction factors.
Since the multi-constituent to be registered (EC 700-483-4) contains as main ingredient 'diallyl 2,2'oxydiethyl dicarbonate', the experimental data from this substance were used in a read-across approach.
