Administrative data

Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1931 - 1943
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Studies are old and the purity of the samples is not known, but nevertheless a good standard deviation of the data of +- 0.3 m/s² was obtained and the results are therefore considered reliable.

Results and discussion

Surface tension
Surface tension:
> 22.6 - < 23.1 mN/m
Temp.:
20 °C

Any other information on results incl. tables

Data from between 14°C up to 41°C are given in the reference documents as follows (in g/s² = mN/m):

23.46 at 14.1°C
 22.46 at 23.3°C
 20.3 at 41.2°C
 23.56 at 15°C
 22.9 at 20°C
 21.74 at 30°C
 23.1 at 20°C
 22.5 at 25°C
The

standard deviation on the basis of three data points at 20°C is 0.25 g/s²

Applicant's summary and conclusion

Conclusions:
A surface tension of 23 mN/m can be concluded from the Beilstein publication database.
Executive summary:

A summary of published data on the surface tension of 2 -bromopropane yields 23 m/ s² as average at a temperature of 20°C. The standard deviation is estimated to be +- 1 m/s².

It should be noted, that in accordance with column 2 of REACH Annex VII, the surface tension study (required in section 7.6) does not need to be conducted as, based on structure, surface activity is not expected from 2 -bromopropane.
