Atmospheric pressure: Determination 1 and 2: 100.2 kPa

Determination 3 and 4: 102.2 kPa

Decomposition temperature (determinations 1 and 2): 250.6 °C (523.7 K)

Overall result: Decomposition at approximately 250.6 °C (523.7 K) at 101.2 kPa.

Conclusions:
The test item has been determined to decompose at approximately 250.6 °C (523.7 K) at 101.2 kPa. As the test item decomposed, no value for boiling point could be determined.
Executive summary:

The general physico-chemical properties of Formaldehyde, reaction products with aniline, 4,4'-methylenebis[phenol] have been determined.

Boiling Point. Decomposed from approximately 250.6 °C (523.7 K) prior to boiling at 101.2 kPa, by differential scanning calorimetry, designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008, and Method 103 of the OECD Guidelines for Testing of Chemicals. As the test item decomposed, no value for boiling point could be determined.
