- Executive summary:
A study was conducted to determine the density of the test substance, trichloro(N,N-dimethyloctylamine)boron according to OECD Guideline 109 and EU method A.3 in compliance with GLP (pycnometer method). Glass vessel was placed in the sample cell, weighed and placed into the pycnometer. Triplicate pressure readings (P1(sample) and P2(sample)) were taken after pressurizing the reference cell of known volume (Vref) and then switching to the sample cell (Vcell). These readings were used to calculate the volume of the glass vessel. The ambient temperature was recorded. Under the study conditions, the density of the test substance was determined to be 1.148 x 103 kg/m3 at 20.0 ± 0.5 ºC. The corresponding relative density calculated to be 1.148 (Harlan, 2014).
Reference
Results
Calibration:
The pressure readings and the calculated volume for the reference and sample cells are shown in the following table:
Determination | P1 (psi) | P2 (psi) | P3 (psi) | P4 (psi) | Reference Cell Volume (cm3) | Sample Cell Volume (cm3) |
1 | 17.216 | 6.511 | 17.246 | 8.537 | 90.640 | 149.026 |
2 | 17.101 | 6.472 | 17.206 | 8.521 | 90.776 | 149.082 |
3 | 17.296 | 6.548 | 17.245 | 8.542 | 90.848 | 149.119 |
Mean reference cell volume: 90.755 cm3
Mean sample cell volume: 149.076 cm3
As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm3and 149.225 ± 1.0 cm3, respectively) the gas comparison pycnometer was therefore considered acceptable for use.
Sample:
The pressure readings and volumes obtained for the vessel and the vessel containing test item are shown in the following table:
Determination | Test | Vessel | Vessel and Test Item | ||||
P1(sample) | P2(sample) | Volume | P3(sample) | P4(sample) | Volume | ||
1 | A | 17.303 | 6.959 | 14.176 | 17.134 | 7.786 | 40.114 |
B | 17.280 | 6.951 | 14.216 | 17.161 | 7.799 | 40.133 | |
C | 17.139 | 6.894 | 14.207 | 17.141 | 7.790 | 40.135 | |
2 | A | 17.134 | 6.902 | 14.534 | 17.213 | 7.849 | 40.804 |

C | 17.226 | 6.937 | 14.468 | 17.202 | 7.844 | 40.804 |
The calculated mean volumes and calculated densities are shown in the following table:
Determination | Mean Volume | Mean Volume | Volume of | Density (kg/m3) |
1 | 14.200 | 40.127 | 25.928 | 1.1480 x 103 |
2 | 14.522 | 40.827 | 26.304 | 1.1489 x 103 |
Mean density: 1.148 x 103kg/m3
Relative density: 1.148
Temperature: 20.0 ± 0.5 ºC
Discussion:
The test item had to be melted to aid sampling. The Sponsor had specified that the test item could be heated to a maximum of 80 °C.
Two determinations were performed to ensure a reproducibility of less than ± 20 kg/m3was obtained.
Description of key information
The density was determined according to OECD Guideline 109 and EU method A.3 (Harlan, 2014).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.148
