GLP compliance:
Type of method:
pour point
Melting / freezing pt.:
ca. 253 K
Atm. press.:
1 013 other: hPa
Remarks on result:
other: ± 3°C
The melting point of the substance as determined by pour point is -20 ±3°C (253K).
Executive summary:

A package of testing, including a determination of the freezing point, was conducted to determine the physico-chemical properties of the test material DPGDB. The determination of freezing point was conducted according to ASTM guidelines, and in compliance with GLP.

The freezing point of the test material DPGDB was determined by pour point to be -20°C (253K).

Description of key information

The freezing point of DPGDB was determined by pour point to be -20°C (253K) (HLS 1999, VCL249/972399).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-20 °C
