1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
Experimental test result performed using standard test guidelines
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Principles of method if other than guideline:
The boiling point of a liquid is the temperature at which that liquid is converted to a gaseous state. It can be defined as the temperature at which the vapour pressure of the liquid becomes equal to the pressure at the surface of the liquid. The boiling point determination of Test item Potassium hydrogen phthalate (CAS No. 877-24-7 ) was done as per the test guideline OECD 103. The method followed was according to Siwoloboff.
GLP compliance:
no
Type of method:
