EC number: 903-919-3 | CAS number: -
Using the correlation log k’ / log KOC, the log KOC corresponding to the peaks of the test item of reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) was in the range of 0.968 – 2.120.
The chromatogram of the test item gave three peaks. With the help of the calibration, the log KOCwas determined in the range of 0.968 –2.120.
Variations in the retention times of reference items and test item are very small. Therefore a stable configuration of the HPLC-column can be assumed.
The correlation log k’/log KOCis sufficiently accurate, as calibration gave a coefficient of determination r2= 0.9541.
No observations were made which might give doubts concerning the validity of the study outcome.
The result is considered as valid.
Literature / (Q)SAR log Koc values of the main components of the reaction mass lie within the same range as the experimentally determined values discussed above: DSBE: 2.2 (1); DIPE: 1.5 (1); SBA: 0.63 (1); TBA: 0.48 (1), thus confirming the validity of the measured data.
