Applicant's summary and conclusion
- Conclusions:
- In a study conducted according to guideline no boiling point was found prior to decomposition which started at 124,2°C.
- Executive summary:
The boiling point of Neodecanoic acid, tin(2 +) salt (2:1) was investigated in a study conducted according to OECD Guideline 103 (Boiling point/boiling range) and EU Method A.2 (Boiling Temperature) and using the DSC method.
In the TGA test, a sample of the test item was heated from 30 °C to 300 °C in an inert gas
atmosphere (N2). A first drop was detected beginning at 124.2 °C (onset). The main drop was
detected beginning at 245.2 °C (onset). Up to 124.2 °C the weight loss was below 5 %, at 245. °C
the total weight loss of 27.3 % was recorded.
Above 245.2 °C (onset) the weight continuously decreased and reached a loss of approx. 93 % at
300 °C.
The recorded main weight loss above 245 °C (estimated onset on TGA) may indicate a beginning
evaporation (boiling), however, with respect to the chemical nature a decomposition of the test
item appears to be more likely.
In order to provide evidence for this assumption, a degradation test was performed during which
an aliquot of the sample was heated to 220°C for 15 minutes and the remaining residue war
characterised by NMR spectroscopy. The NMR analysis confirms the decomposition of the
product as in increased amount of free neodecanoic acid was detected. The appearance of free
acid explains the weight loss drop at 245.2 °C as begin of the boiling range of the used
neodecanoic acid.
Consequently, Zinn-Neodekanoat does not provide a boiling point until disintegration at about
220 °C.
