Referenceopen allclose all
The test substance is composed of several compounds. No simple boiling temperature can therefore be expected.
The colour of the test substance changed from yellowish to yellowish-brown at 205 °C, to brown at 220 °C, to dark brown at 240 °C and to black at approximately 265 °C. At about 220 °C the test substance started boiling and bubbles. Identical observations were made in both samples.
The test substance decomposed before and during boiling. Decomposition was indicated by change of colour starting at about 205 °C. The decomposed test substance boiled from about 220 °C on.
The calculated boiling temperatures of the three main components of the test substance are in approximative agreement with the experimentally determined results.
The calculated boiling temperatures of the three main components are in approximative agreement with the experimentally determined results.
