- Validity criteria fulfilled:
- not applicable
- Conclusions:
- The authors tested the hydrolysis of benzotrichloride in light and heavy water following a methodology described by Robertson R.E. in 1955 (Canadian Journal of Chemistry, 33, 1536). In the test conditions, the hydrolysis rate of the test substance was 387 +/- 5 (kH20X 10E5 sec-1) for hydrogen oxide and 307 +/- 15 (kD20X 10E5 sec-1) for deuterium oxide. Using the formula t1/2 = ln 2 / (kH20) the half-life was calculated which are 2.99 min in hydrogen oxide and 3.76 min in deuterium oxide. The relation of rate ratios (kD20 / kH2O) is 0.79.
- Executive summary:
The authors tested the hydrolysis of benzotrichloride (CAS n° 98-07-7) in light and heavy water following a methodology described by Robertson R.E. in 1955 (Canadian Journal of Chemistry, 33, 1536).
In the test conditions, the hydrolysis rate of the test substance was 387 +/- 5 (kH20X 10E5 sec-1) for hydrogen oxide and 307 +/- 15 (kD20X 10E5 sec-1) for deuterium oxide at 5.10°C. Hence, using the formula t1/2 = ln 2 / (kH20), the half life values for the test substance in hydrogen oxide and deuterium oxide are 2.99 min and 3.76 min respectively. The relation of rate ratios (kD20/kH20) is 0.79.
GLP standards are not specified but this study should be considered as reliable with restrictions as it is well documented, meets generally accepted scientific principles and is acceptable for assessment.
