Key result

Atm. press.:

1 013 hPa

Decomposition:

yes

Remarks:

The test item loses its identity at an average temperature of 230.0°C, arrived from three replicate determinations, i.e., the test item decomposed fully at 230°C

Decomp. temp.:

230 °C

The individual melting point of reference standard Viz., azobenzene, benzoic acid and caffeine was found to match with literature values. This augments that the performance of the melting point apparatus was suitable enough to determine melting point of the test item.

Instrument performance check
Reference Item
Reference Item	Melting point °C
Azobenzene	68.4
Benzoic acid	121.5
Caffeine	234.4

Test item
Test item	Decomposition Temperature °C
Preliminary	230.8
Replicate 1	228.2
Replicate 2	230.2
Replicate 3	231.6
Mean*	230.0

Conclusions:

The test item decomposes at temperature of 230°C, (average of three replicate determined values).

Executive summary:

The test item decomposed at 230.0°C, during experimentation on melting point determination. This clearly reveals that the test item loses its identity at 230.0°C (average of three replicate determined values). The measurement was carried out at one atmospheric pressure.

Description of key information
