Executive summary:

Test item tall oil, maleated was tested to determine its boiling point according to OECD Guideline for the Testing of Chemicals. Test No. 103 (July 27 1995) Boiling Point.

An initial observation of the test item behaviour at elevated temperatures up to 300 °C was conducted using the Kofler Hot Bar Method, slightly modified. The test item was placed on the bar in a thin layer and then heated to above 300 °C. The test item was observed for any decomposition or change of state. No signs of decompostion were observed. The boiling point was measured according to the Siwoloboff method. This technique employs a 5 mm ID glass sample tube and an inner capillary tube (1 mm ID) with a fused section 1 cm from the end. Duplicate sample tubes contained 0.1 grams of test item each. The sample tube and capillary were immersed in silicone oil in the Thiele apparatus, along with a calibrated thermocouple, and heated by a propane torch. The boiling point was judged as described in OECD Test No. 103.

The test item did not boil below 300 °C. Therefore, tall oil, maleated has a boiling point greater than 300 °C (573 K).

Description of key information
