In-house test procedure VTA(S)31X93002.02: "Boiling temperature determination(Tb) of solid and liquid substances by means of DSC"

GLP compliance:

no

Type of method:

differential scanning calorimetry

Boiling pt.:

ca. 187 °C

Atm. press.:

1 036 hPa

Decomposition:

yes

Decomp. temp.:

ca. 187 °C

Remarks on result:

other: possibly decomposition during boiling

A defined value for the boiling point of test item Alcohols, C10 -12, Ethoxylated (EO < 2.5) could not be determined based on the effects observed in the DSC experiments. The DSC curve, i.e. the peak shape and peak magnitute, indicates boiling and/or thermal decomposition starting at ca. 187 °C (at 1036 hPa).

190 °C (from first measurement)

185 °C (from second measurement)

187 °C (from third measurement)

192 °C (from fourth measurement)

182 °C (from fifth measurement)

Description of key information

boiling and/or thermal decomposition starting at ca. 187 °C at 1036 hPa (OECD 103, DSC)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

187 °C

Additional information

The boiling point of the substance was determined with differential scanning calorimetry according to OECD Guideline 103. The DSC curve shows various effects attributed to boiling and/or thermal decomposition starting at ca. 187 °C (at 1036 hPa).
