- no
- Remarks on result:
- other: The test item did not melt but showed colour change from green to black.
- Conclusions:
- The test item does not melt but showed colour change from green to black. The mean decomposition temperature of Formaldehyde, reaction products with N, N-dimethylbenzenamine and N-methylbenzenamine, oxidized, hydrochlorides (CAS No. 83968-28-9) was found be 186.8 °C at 978.5 hPa.
- Executive summary:
The melting point determination of Test item Formaldehyde, reaction products with N,N-dimethylbenzenamine and N-methylbenzenamine, oxidized, hydrochlorides(CAS No. 83968-28-9) was done as per the test guideline OECD 102. The method followed was according toCapillary/metal block. The test item did not melt but showed colour change from green to black. Thus, the decomposition temperature was found to be 186.8 °C at 978.5.hPa.
