EC number: 252-744-2
CAS number: 35836-73-8
Two experiments were performed at 984 hPa:
- boiling point measured in the first
experiment: 511 K (238°C)
- boiling point measured in the second
experiment: 513 K (240°C)
- mean: 512 K (239°C)
The two results showed a difference of 1 K
(within the required limit of 2 K max).
For high boiling temperatures, the mean
measurement error with this method is +/- 5 K. Therefore the boiling
temperature at standard pressure was not calculated with the Sidney
Young equation, as the possible correction of +/- 1.5 K is lower than
the measurement error.
The boiling point was measured twice
according to Siwoloboff's method. Results were 238°C and 240°C at 984
hPa (+/- 5°C).
From these results, the boiling point at 984
hPa was stated as 239°C +/- 5°C.
No observations were made which might cause
doubts on the validity of the study outcome. Therefore, the result of
the study is considered as valid.
The boiling point was determined according to Siwoloboff's method.The boiling point of nopol is 239°C +/- 5°C at 984 hPa.
Key study conducted according to OECD 103
Guideline and EU Method A.2. The result is thus scientifically
acceptable but not obtained under GLP.
The Siwoloboff method recommended for pure
substances and mixtures in the OECD guideline does not allow to
determine a boiling point range. This is considered as acceptable for
the purpose of REACH registration.
A reliability of 2 (reliable with
restrictions) is assigned to the study.
