- Executive summary:
This boiling-point study was conducted according to GLP, to OECD guideline 103 (a modification of the Siwoloboff procedure) and to OPPTS 830.7220.
The definitive boiling point testing did show an initial emergence of bubbles (start of boiling range) at a corrected or normalized temperature of 210.3 ± 0.7°C (483.4 K). However, no definitive boiling point was observed.
Reference
A boiling point approximation test (Rapid Scan) did result in a measurable boiling point of approximately 240°C (513 K) and a boiling range of 220 (493 K) to 240°C (513 K). These results were used to determine the range of temperatures used in the definitive test. The Rapid Scan testing was performed at a temperature gradient of 5°C per minute; the definitive testing was performed using a gradient of 1°C per minute. During the definitive testing the barium sulfonate test substance samples did display an initial emergence of bubbles (start of boiling range) at a mean corrected or normalized temperature of 210.3 ± 0.7°C (483.4 K) - for the three tests. An increase in the bubble frequency was observed at approximately 300°C for each sample. However, the rate of bubble production did not approach that of a true boiling point. The testing was discontinued at 350°C as the samples underwent thermal degradation and rendered a visible boiling point endpoint impossible. Upon removal from the instrument (at test termination), the barium sulfonate test substance was almost black in color. Results of the normalized (normal) boiling point data, corrected to standard barometric pressure, for the barium sulfonate test substance are presented in Table below.
