The DSC measurement was combined with a
thermogravimetric (TG) measurement. The heat flow curve shows a larger
endothermic effect starting at 560 °C (extrapolated onset) with peak
maxima temperatures at 623 and 677 °C. Simultaneously to the endothermic
heat flow, however, a significant mass loss is observed. After cooling
down, the sample holder, the reference crucible as well as the sample
crucible are covered with a grey precipitation (sample crucible inside
and outside). As residue remains a dark-grey powder. Therefore the
endothermic peak cannot be related to melting, but to decomposition
and/or sublimation. No melting point was determined prior to the
decomposition and/or sublimation of the test item, starting at approx.
The melting point of tin disulfide was
determined with the DSC method combined with the TG method according to
EU method A.1 and OECD 102 to be above 515°C. Above this temperature
decomposition and/or sublimation was observed. For the risk assessment
the most conservative value, i.e., 515 °C, will be used.
This melting temperature is considered to be
relevant and reliable for the further risk assessment.
> 515°C, decomposition and/or sublimation starts at 515°C
non-GLP Klimisch 1 key study (Paß 2011), the melting point of tin
disulfide was determined with the DSC
method combined with the TG method according to EU method A.1 and OECD
102 to be above 515°C. Above this temperature decomposition and/or
sublimation was observed. For the risk assessment the most conservative
value, i.e., 515 °C, will be used.
