Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
25-04-2017 – 25-04-2017
Reliability:
1 (reliable without restriction)
Justification for type of information:
Experimental result performed using standard methods of analysis
Reference:
Composition 0
Qualifier:
according to
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Principles of method if other than guideline:
A sample is heated gradually in a tube which is immersed in a liquid bath. The sample tube is held in close contact with a thermometer and it contains a boiling capillary which is fused about1 cm above its lower end. Upon approach of the boiling temperature bubbles emerge rapidly from the lower open end of the capillary. The boiling temperature is that temperature at which, on momentary cooling, the string of bubbles stops and liquid suddenly rises in the capillary.
GLP compliance:
no
Type of method:
method according to Siwoloboff
