- Executive summary:
BOILING POINT
In compliance with Commission Directive 92/69/EEC - A2 method (1992) OECD Guideline No. 103 (1995)
AMENDMENTS No amendment to the study plan was requested.
DEVIATIONS No incident, which could have affected the quality or the interpretation of the results obtained, was observed.
RESULTS The test item was melted at approximately 70°C before the assay. At 82.6°C, it turned from brown / orange to yellowish. Then, at 98.5°C, it produced black solid particles, rising in the test tube. Remark: the temperature recorded are the vapour’s one.
CONCLUSION No boiling range could have been determined in our experimental conditions because of the test item degradation before coming to boil, as early as 98.5°C.
Reference
No boiling range could have been determined in our experimental conditions because of the test item degradation before coming to boil, as early as 98.5°C.
