Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
