Description of key information
GLP Study according to EU Method A.16.
General Physical Chemistry, Schering AG, Berlin.Study report No. NJ24EY10 (APC 102/99), dated 1999-11-08.
No self-heating was observed below 181 °C.
Key value for chemical safety assessment
Additional information
Method:
The substance was filled in a cube (20 x 20 x 20 mm3) made of a piece of stainless steel wire mesh with 0.045 mm openings. The cube was placed on a rack with a wide open mesh of steelwire. To measure the sample- and oven-temperature one thermocouple was placed directly in the middle of the substance-filled cube, the second thermocouple was placed approximately 20 mm next to the cubewall. The oven was heated by a rate of 0.5 K / minute from room temperature to 181 °C. The ramp wasn’t completed up to 400 °C because the melting point of the substance was obtained at 185.5 °C (Report No. NC46EY10 ( APC 70/99), melting point by DTA according to EU Method A.1). The signals of the thermocouples were recorded on a multi channel dot-recorder.
Results:
- Between 60 °C and 168 °C the oven- and sample-temperature increased with the same rate (0.5 K / minute).
- Above 168 °C the sample-temperature increased with a rate < 0.5 K / minute and the substance started melting and the lightly brown melt dropped from the stainless wire mesh cube.
- The heating ramp was stopped at 181 °C (melting point 185.5 °C, see above)
Therefore, no self-heating or a self-ignition temperature of solid Hydroxydropirenone exist below 181°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
