Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

August - November 2014

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

test procedure in accordance with national standard methods with acceptable restrictions

Qualifier:

equivalent or similar to guideline

Guideline:

DIN EN 15188 (Determination of the spontaneous ignition behaviour of dust accumulations)

Principles of method if other than guideline:

Deposited dust: This test determines the ignition temperature of a dry product on a hot surface. For a description of the method see "any other information on materials and methods".

GLP compliance:

not specified

Key result

Relative self-ignition temperature:

> 360 °C

Remarks on result:

preliminary test

At all of the tested temperatures (240, 270, 300, 330 and 360 °C) no ignition of desposited 2',4'-Bis(methoxycarbonyloxy)-2-brom-acetophenone was observed. Only melting and foaming of the test substance occured.

Conclusions:

No auto-ignition of deposited 2',4'-Bis(methoxycarbonyloxy)-2-brom-acetophenone dust occurred on surfaces until 360°C.

Executive summary:

The test determines the ignition temperature of a deposited dusty test substance on hot surfaces. The test is conducted according to the test protocol. The surface area of the substance is increased intentionally in this test by preparing the test substance accordingly to simulate the deposited dusty properties. The ignition temperature of deposited dusty test material is expected to be lower than the ignition temperature of the solid with larger particle diameters. At the hottest temperature in this test (360°C) there was no auto-ignition of deposited 2',4'-Bis(methoxycarbonyloxy)-2-brom-acetophenone dust observed.

Description of key information

Two tests for dusty 2',4'-Bis(methoxycarbonyloxy)-2-brom-acetophenone are available evaluating the auto-flammability on a hot surface for deposited and dispersed 2',4'-Bis(methoxycarbonyloxy)-2-brom-acetophenone. No auto-ignition of deposited 2',4'-Bis(methoxycarbonyloxy)-2-brom-acetophenone dust occurred on surfaces until 360°C. Nevertheless the autoflammabilty temperature of dispersed dust of 2',4'-Bis(methoxycarbonyloxy)-2-brom-acetophenone was tested to be 425 °C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

425 °C

Additional information

No auto-ignition of deposited 2',4'-Bis(methoxycarbonyloxy)-2-brom-acetophenone dust occurred on surfaces until 360°C.

The autoflammability temperature of dispersed dust of 2',4'-Bis(methoxycarbonyloxy)-2-brom-acetophenone was tested to be 425 °C.
