Key result

Flash point:

194.5 °C

Atm. press.:

101 325 Pa

 Pre-test for safety

All observations of the Pre-test following Siwoloboff are presented in the following table.

 Pre-test following Siwoloboff

Observations	Temperatures in °C
Test item got darker	Since 240
A lot of small bubbles	385
Gas burner turned off (lots of small bubbles)	400

 

After cooling down the test item was darker ( dark brown) than the original test item.

      

Determination of the Flash Point

The results of the determinations are presented in the following tables.

 Findings

Program	Expected flash point (setting) in °C	Flash point (found) in °C	Mean in °C	Notes
Search	365	190.8		not used for calculation(pre-test)
EN ISO 2719-A	191	195.5	194.5	difference < 2 K
EN ISO 2719-A	191	193.5

Interpretation of results:

GHS criteria not met

Conclusions:

First, a safety test was performed: approx. 3 mL of the test item was heated with a Bunsen burner up to the temperature of 400 °C. The colour of the test item got darker (dark-brown) after cooling down.
Then, a pre-test and a main test with two experiments were performed using a flashpoint tester.
The flashpoint of 7-(4-ethyl-1-methyloctyl)quinolin-8-ol is stated as 194.5 ± 1.0 °C (corresponding to 467.7 K ± 1.0 K). The flash point is given as the mean value of the duplicate determination.

Description of key information

One key study is performed in accordance with EU Test Method A.9 under the conditions of GLP.
