Endpoint:
auto-flammability
Type of information:
experimental study
Adequacy of study:
key study
Study period:
06-Oct-2008
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Remarks:
no GLP
Qualifier:
according to
Guideline:
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
Version / remarks:
DIN 51794
Deviations:
no
Principles of method if other than guideline:
The auto-ignition temperature is the lowest temperature at which the test item will ignite when mixed with air under the conditions defined in the test method. The test method determines the minimum temperature of the inner surface of an enclosure that will result in ignition of gas, vapour or liquid injected into the enclosure.
GLP compliance:
no
Specific details on test material used for the study:
- Name of test material (as cited in study report): Isodecyl methacrylate (IDMA)
- Substance type: organic
Key result
Auto-ignition temperature:
295 °C
Atm. press.:
1 003 hPa

Lowest value of the initial experiment: 75 - 650 °C

Lowest value of the main experiment:  303   °C

Lowest value of the 1st repeat:           300   °C

Lowest value of the 2nd repeat:         285   °C

Autoignition temperature:              295       °C *

* The autoignition temperature (result of all measurements) is lowest of all low values, rounded down to a multitude of 5 °C.

Conclusions:
The auto- ignition temperature was determined to be 295 °C at 1003 hPa according to DIN 51794.
Executive summary:

The auto- ignition temperature was determined to be 295 °C at 1003 hPa according to DIN 51794.

Description of key information

No study exists for the auto flammablity for n-Dodecyl methacrylate.

Read across to the individual substance i-Decyl methacrylate (IDMA, CAS: 29964 -84 -9) and structural analogue UVCB substance

C12 -C16 methacrylate (LIMA, CAS: 90551 -76 -1):

i-Decyl methacrylate: Auto flammability: 295 °C at 1013 hPa, DIN 51794 equal to EU Method A 15, experimental data (Rediske N (2008)

C12 -C16 methacrylate: Auto flammability: 240 °C at 994 hPa, DIN 51794 equal to EU Method A 15, experimental data (Rediske N (2008)

In analogy to the related substance Isodecyl methacrylate the auto ignition temperature of Dodecylmethacrylate is approximately 295 °C at normal pressure.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
295 °C

Additional information

In analogy to the related substance Isodecyl methacrylate the auto ignition temperature of n-Dodecyl methacrylate is approximately 295 °C at normal pressure. (Evonik RohMax (2008)).
