Endpoint:
melting point/freezing point
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
weight of evidence
Study period:
11 May 2011
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Guideline study. According to the ECHA guidance document "Practical guide 6: How to report read-across and categories (March 2010)", the reliability was changed from RL1 to RL2 to reflect the fact that this study was conducted on a read-across substance.
Justification for type of information:
See IUCLID section 13.2 for analogue justification.
Reason / purpose for cross-reference:
read-across source
Qualifier:
according to guideline
Guideline:
other: ASTM D 97-02
Deviations:
no
GLP compliance:
no
Type of method:
pour point
Melting / freezing pt.:
-57 °C
Atm. press.:
ca. 1 013 hPa

There are no values given for pressure but assumed to be measured at normal pressure (1013 hPa). No information is given on specification on decomposition/sublimation temperature.

Conclusions:
The Pour Point of TEGDA was determined to be -57 °C.
Executive summary:

The Pour Point of TEGDA was determined to be -57 °C.

Description of key information

<-20 °C at ca. 1013 hPa

Key value for chemical safety assessment

Additional information

The melting/freezing point of the substance 1,3 -butylene diacetate (CAS 1117 -31 -3) was deduced from similar substances: Ethylene diacetate (CAS 111 -55 -7) has a melting point of -78 °C, the 2,2'-[ethane-1,2-diylbis(oxy)]bisethyl diacetate (Ethylenetriglycol diacetate) (CAS 111 -21 -7) has a melting point of -57 °C.

Therefore the melting point of the substance 1,3 -butylene diacetate (CAS 1117 -31 -3) was deduced to be <-20 °C.
