Tetramethyl 2,2'-[1,4-phenylenebis[imino(1-acetyl-2-oxoethane-1,2-diyl)azo]]bisterephthalate

Melting point / freezing point

Link to relevant study record(s)

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2011

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

test procedure in accordance with national standard methods with acceptable restrictions

Principles of method if other than guideline:

measurement by DSC

GLP compliance:

no

Type of method:

differential scanning calorimetry

Key result

Decomposition:

yes

Decomp. temp.:

> 311 °C

The product starts to decompose in the sealed vial at 311 °C with a mean energy of 334 J/g.

The minor exothermic process in the 246 - 304°C region may lead to a pressure increase in closed systems, if it is due to a partial decomposition.

Conclusions:

The test substance decomposed at >311°C.

Description of key information

Decomposed at >311°C without melting.

Additional information

Nanoform:

The determination was conducted by DSC with a heating rate of 3 K/min.
