EC number: 219-799-4
CAS number: 2536-05-2
From 10 °C up to 280 °C no boiling point could be observed. The
decomposition if the test item starts before a boiling point could be
According to OECD Guideline for Testing of Chemicals No. 103 (Boiling
Point) which conforms with the EU Method A.2 (Boiling Temperature) no
boiling point could be observed up to the decomposition of the test item
at approx. 270°C.
screen a sample of 2,2'-MDI (EC Number: 219-799-4) in order to
determine the boiling point and / or the onset temperature and
magnitude of any exothermic activity.
sample of 2,2'-MDI (EC Number: 219-799-4) was charged to an open
aluminium DSC crucible which was then placed in the furnace. In
the screening test the sample was then ramped from -50C
at 10 K.min-1.
Result : 284 - 340°C Boiling with decomposition
No boiling point could be observed up to the decomposition of the test item.
Exothermal decomposition starts at approx. 270 °C. A second key study reported a decomposition range at 284-340°C
